Year End Summary for 2020

YEAR END SUMMARY
STATION NAME: Little Cannon River nr Cannon Falls, CR24
STATION NUMBER: H39016001
YEAR: 2020
PREPARED BY: Fred Bowen, fred.bowen@state.mn.us

CLIMATE SUMMARY: 
Division 9, 2020: Mild conditions and near-normal snowfall January through into April topped off a moderately snowy early winter, leading to normal to slightly above-normal seasonal snowfall totals of 35-55 inches. The May-September growing season was warm and slightly wet, punctuated by very warm June through August conditions, and occasional bouts of heavy rainfall. A widespread heavy rainfall event on June 28-29 produced 4-6 inches near the Cannon and Vermillion rivers, with other 2-4-inch rains falling on May 17 and June 10. Temperatures fell below freezing in early October, but with little precipitation falling, the liquid precipitation season extended to October 15. Snow fell occasionally from mid-October into early November, with most of the area seeing totals of 4-8 inches by the end of November. Extreme warmth melted much of the snow during early-mid November, and the rest was melted by persistently mild conditions during the remainder of the month. No snow was on the ground as of December 1.

STATION OPERATION SUMMARY: 
Is this site monitored year round? No 
Open water dates - estimated Ice out and Ice in: Ice out 3/8/2020, Ice in 12/1/2020
Open water sites ONLY. Period of data record (if different from ice out/ice in dates): 3/8/2020 - 11/1/2020
Summary of equipment - related factors that impacted data collection: Station was down from  5/25/2020 - 6/10/2020 with no data being logged or transmitted. This period was estimated in daily Qs.

DISCHARGE SUMMARY:
Number of flow measurements for monitoring season: 3
Was the full range of flows measured for the season? NO, highest calculated discharge = 1390 cfs, highest measured discharge = 179 cfs, 13% of highest calculated discharge 
Was a new rating developed? YES. Created Rating 9.0. Low flows over the last couple years were showing scour. Adjusted rating below 540 cfs to account for this trend. Used 3/3/2021 msmnt to define low end and changed log offset to 6.95 ft.
General summary of control changes/shifts needed: Deposition shift applied end of July through the end of the year based on the 9/2/2020 measurment.
Quality of computed daily discharges: Estimated due to COVID and a regression to estimate the discharges during equipment issues. The rest are mostly good and fair due to rating quality.

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this site? YES 
Climatological liquid precipitation period: 4/16/2020 - 10/16/2020
Was there a complete and acceptable precipitation record for this period? NO, station data between 5/25 - 6/10 was non-existent and missed a large event.


DISCLAIMER: In the spring and summer of 2020, field work was limited due to the COVID 19 related travel and work restrictions. Because of this, there are less frequent discharge measurements, which can lead to more uncertainty and data estimation. This is reflected in the quality codes of the discharge data.

YEAR END SUMMARY
STATION NAME: Little Cannon River nr Cannon Falls, CR24
STATION NUMBER: H39016001
YEAR: 2019
PREPARED BY: Erin Spry; erin.spry@state.mn.us

CLIMATE SUMMARY: : The wettest year on record, with annual surpluses of 12 to over 20 inches (35-70%). Cold and stormy conditions from the end of January through April contributed to seasonal snowfall totals of 65 to 85 inches, generally 45 to 70% above 1981-2010 averages. The first four months of the year were 4.3 degrees F below average, with a deficit of 8.8 degrees F in February. The May - September growing season was mild and extremely wet, with notable surpluses every month except August. Excessive rains of 4-6 inches with severe flooding occurred in the Rochester area on June 28, and near Harmony and Mabel on September 19. At least four other events led to localized daily totals in excess of three inches. The wet, cool conditions prevailed through the remainder of the year, with October receiving more than two times its average precipitation, and the seasonal snowpack forming during the end of November.

GAGE OPERATION SUMMARY:
Is this site monitored year round? NO
Open water dates - estimated Ice out and Ice in: 03/14/2019 - 11/14/2019
Open water sites ONLY. Period of data record (if different from ice out/ice in dates): same
Summary of equipment - related factors that impacted data collection: Performed well.
Number of flow measurements for monitoring season: 7
Was the full range of flows measured for the season? YES. Highest measured flow this season (2710.0 cfs, 03/14) is 83% of highest calculated flow (3250 cfs)

DISCHARGE SUMMARY:
Was a new rating developed? NO
General summary of control changes/shifts needed: Event based shifting due to changing scour/deposition controls
Quality of computed daily discharges: good (majority) to estimated due to sensor corrections and rating qualities

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this station? YES
Climatological liquid precipitation period: 05/01/2019 - 10/31/2019
Was there a complete and acceptable precipitation record for this period? NO
Rain bucket tracked poorly throughout all of July, rejected entire month per SCO's recommendation. Logger reset occurred 05/08/2019 during a precip period - totals were off for the day due to lack of data. Data was rejected per SCO's review and recommendation. Data was kept for remainder of month because rain bucket tracked well for that period.

Precipitation Data Summary
--------------------------------------------------------------------------------
The precipitation record tracked correctly and was complete for the monitoring
season.
At least three field visits were made to check the rain gage for obstructions
during the monitoring season.
There was no visual evidence or an indication from analysis of the precipitation
data that the rain gage was plugged at any time during the monitoring season.
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values.
The rain gage was not calibrated within the last three years. Rain bucket was
installed in 2009 but we don't know if it had been recalibrated since the bucket
was manufactured in 1999. Although the bucket has not been recently calibrated,
it does not appear to affect the data.

Flow Data Summary
--------------------------------------------------------------------------------
Site visits to determine if the logger was tracking stage correctly were done at
a frequency of 8 weeks or less.
The stage record either did not track correctly or was not complete for some
parts of the monitoring season. Orifice line was buried through 7/23/15 site
visit causing questionable data and a period of estimated data from 5/19/15 to
7/1/15.
Stage either did not track correctly or was not complete during some or all
moderate to high flow periods this season.
Incorrect or missing stage values were not accurately adjusted or estimated using
a technique that introduced less than 15% error in total seasonal flow volume.
Summation of questionable/estimated discharge based on daily mean is 7,736 cfs
which is 56% of the sum of the total year flow of 13,880 cfs.
Other stage data collection factors: Buried orifice line for half the year was
the only issue.
8 flow measurements were taken during the monitoring season.
All recorded stage values were within the rating or less than 1 foot above the
rating with no change in channel control. Highest recorded stage = 9.299 ft on
7/19/2015, highest measured stage on rating = 13.760 ft from 6/8/2005.
Flow measurements were taken this year with a maximum frequency of 4-5 weeks or
with a frequency that accurately reflects seasonal conditions.
Flow measurements cover less than 70% of the highest recorded seasonal/annual
discharge.
Flow measurements cover less than 40% of the highest recorded seasonal/annual
discharge.
Flow measurements cover less than 15% of the highest recorded seasonal/annual
discharge. Max calculated flow = 320.021 cfs on 7/19/2015, Max measured flow =
46.8 cfs on 3/13/2015 which is 14% of max calculated flow.
Site visits to determine if the physical characteristics of the control changed
during the monitoring season were done at a frequency of 5 weeks or less.
A change in the physical characteristics of the control occurred at some time
during the monitoring season.
Change in control: Deposition effected flows early May through early July.
Deposition was washed out during July to mid August. Deposition once again
effected flows from mid August to mid September. Flows remained uneffected from
mid September to ice in.
Adequate flow measurements were taken to confidently adjust stage during
period(s) of altered control.

Precipitation Data Summary
--------------------------------------------------------------------------------
The precipitation record tracked correctly and was complete for the monitoring

There was no visual evidence or an indication from analysis of the precipitation
data that the rain gage was plugged at any time during the monitoring season.
Rain bucket wiring was found disconnected during 7/23/2015 visit but July still
considered "good" by comparing well with climatology data.
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values.
The rain gage was not calibrated within the last three years. The bucket was
installed in 2009, but we don't know if it had been recalibrated since it was

Flow Data Summary
--------------------------------------------------------------------------------
Site visits to determine if the logger was tracking stage correctly were done at
a frequency greater than 8 weeks.
The stage record tracked correctly and was complete for the entire monitoring
season. Site only checked a few times this year so data quality is unknown due
to it being a Limited Flood Warning Gage.
Other stage data collection factors: Stage data spikey at times most likely due
to a buried orifice line.
2 flow measurements were taken during the monitoring season.
All recorded stage values were within the rating or less than 1 foot above the
rating with no change in channel control. Highest recorded stage was 12.139 ft
on 3/31/2014, highest measurement on rating = 13.760 ft on 6/8/2005
Flow measurements were taken this year with a frequency greater than 4-5 weeks
and do not accurately reflect seasonal conditions. This is a flood gage site and
measurements are taken 1 - 2 times a year
This site does not have a permanent fixed type control structure.
Flow measurements were taken with a frequency greater than 7 weeks and do not
capture moderate flows (50% of maximum seasonal discharge).
Flow measurements were taken with a frequency greater than 7 weeks and do not
capture moderate to low flows (25% of maximum seasonal discharge). There were
two flow measurements taken this year. The highest measurement was taken on
4/8/2014 which had a stage of 8.40 ft and a discharge of 115 cfs. The highest
recorded stage was on 3/31/2014 of 12.139 ft. This gage is visited minimally
during the year, usually just in the spring during high flow and again in the
fall for a maintenace check. If there are high flow events throughout the summer,
gages are visited as needed. These minimal site visits do not meet our criteria
to calculate a reliable discharge record or have confidence in the precipitation
data. There is too much uncertainty in the record and any computation would not
meet our quality standards for a computed discharge record.
Site visits to determine if the physical characteristics of the control changed
during the monitoring season were done at a frequency of greater than 5 weeks.
A change in the physical characteristics of the control occurred at some time
during the monitoring season.
Change in control: Both measurements within banks, April measurement notes a
clear control, October measurement notes heavy debris.
Adequate flow measurements were not taken to confidently adjust stage during
period(s) of altered control. This is a limited flood warning gage so site was

June
rainfall totals were well above historical averages in most Minnesota counties.
July rainfall totals were generally below historical averages in most Minnesota
counties, except in far northern Minnesota and portions of east central Minnesota
where monthly precipitation totals were above average. In the early morning
hours of July 13, continuously redeveloping thunderstorms quickly dropped four or
more inches of rain on portions of east central and south central Minnesota. The
deluge led to numerous reports of rural and urban flooding. In many communities,
especially in east central Minnesota counties, August precipitation totals fell
short of long-term averages by two or more inches. The heaviest rainfall event
of September occurred on the 19th when severe thunderstorms rumbled through
southwest, central, and east central Minnesota. Heavy downpours, hail, and
damaging winds were reported. Isolated locations in Sherburne and Isanti
Counties received two to three inches of rain in less than an hour.

Flow Data Summary
--------------------------------------------------------------------------------
Site vists to determine if the logger was tracking stage correctly were done at a
frequency greater than 8 weeks.
The stage record tracked correctly and was complete for the entire monitoring
season. Site was only checked a few times so data quality is unknown due to it
being a limited flood warning gage.
Other stage data collection factors: Battery was not charging for a period, but
did not affect data collection.
2 flow measurements were taken during the monitoring season.
Some recorded stage values were above the rating by a value greater than 1 foot,
or less than 1 foot with a change in channel control. Highest recorded stage =
15.310 ft on 3/30/2013, Highest stage on rating = 13.76 ft on 6/8/2005
The present rating can be accurately extrapolated or modeled to the highest
recorded stage values.
Flow measurements were taken this year with a frequency greater than 4-5 weeks
and do not accurately reflect seasonal conditions. This is a flood gage site and
measurements are taken 1 - 2 times a year
This site does not have a permanent fixed type control structure.
Flow measurements were taken with a frequency greater than 7 weeks and do not
capture moderate flows (50% of maximum seasonal discharge).
Flow measurements were taken with a frequency greater than 7 weeks and do not
capture moderate to low flows (25% of maximum seasonal discharge). Two flow
measurements were taken this year. The highest flow measurement was taken on
4/18/2013 which had a stage of 9.49 ft and a discharge of 395 cfs. The highest
recorded stage was 15.31 ft on 3/30/2013. This gage is visited minimally during
the year, usually just in the spring during high flow and again in the fall for a
maintenance check. If there are high flow events throughout the summer, gages are
visited as needed. These minimal site visits do not meet our criteria to
calculate a reliable discharge record or have confidence in the precipitation
data. There is too much encertainty in the record and any computation would not
meet our quality standards for a computed discharge record.
Site visits to determine if the physical characteristics of the control changed
during the monitoring season were done at a frequency of greater than 5 weeks.
A change in the physical characteristics of the control occurred at some time
during the monitoring season.
Change in control: All measured flows were within banks. April measurement was
clear control, November measurement was heavy debris affected.
Adequate flow measurements were not taken to confidently adjust stage during
period(s) of altered control. Only 2 measurements were taken this year since the
site is a limited flood warning gage.
The potential error in cumulative flow volume introduced by changing channel
control is less than 15%.
The potential error in cumulative flow volume introduced by changing channel
control is between 5-15%. Flows were not calculated for this year due to minimal
visits and unknown quality because this is a limited flood warning gage.

The
first half of 2012 was warmer on average and saw temperatures that were up to
sixteen degrees warmer than normal in South East Minnesota. The second half of
the monitoring season saw temperatures that varied from average historical temps
with July and November being notably warmer and October being notably colder.
Precipitation was not far off of past averages during the first part of the year
with the exception of May being slightly wetter. Average totals during the
second half of the year were lower than normal with September being much drier
than normal. February? monthly precipitation totals topped the historical
average by more than one inch over most of southern Minnesota. For numerous
southern Minnesota locales, it was among the five wettest Februaries in the
historical record. A large, moisture-laden storm swept across the southern
two-thirds of Minnesota on February 28 through March 1. Rainfall amounts of over
one and one-half inches were reported in many southern Minnesota communities.
Large sections southern Minnesota received three or more inches of rain from May
4 through May 6. On May 23 and 24 over four inches of rain fell in some southern
and eastern Minnesota communities. Heavy thunderstorms on June 14 dropped
rainfall totals of six to eight inches on portions of Rice, Dakota, and Goodhue
Counties. The axis of the heaviest rainfall totals aligned nearly perfectly with
the axis of the Cannon River watershed, amplifying the river flooding. The state
experienced widespread rain on October 23-25.

Data is only collected for a partial year at this site. This is a limited flood
warning gage visited minimally during the year
Data collection began on 03/15/2011.
Data collection ended on 11/26/2011.
The ice out date was 03/15/2011.
Snowmelt conditions: Starting off the year, snow depths varied greatly across
the region and were as much as 16 inches in the southwestern portion of the
region and as little as around 4 inches in the southeast area of the region.
Snow water equivalencies were between 2 and 4 inches of water for almost the
entire area. The bulk of February precipitation in the southern two-thirds of
Minnesota was dropped by a major winter storm that roared through the Midwest on
February 20-21 with 8 to 18 inches of snow falling mostly in the northern part of
the region. A large and intense early-spring storm on March 22-23 brought 6
inches of snow to the most northern part of the region. By April 1st only a
trace of water was left in the southern half of the region with less than an inch
remaining in the little snow that was left. By April 4th the region was snow
free.
Periods the stream was out of its banks: Based on stage data and the rating, the
stream was out of banks from 3/23, 6/22 - 23 and 7/15 -16.
Periods of low or no flow: September through the end of the year stages were
lower

The
first half of 2011 saw temperatures that were one to nearly two and a half
degrees cooler than normal in South East Minnesota. July and October were
notably above average with 4.7 and 4.6 degrees respectively above average.
Precipitation was near or above average for most of the year with more than an
inch more rainfall than normal in April, June, and July. Departures below
average occurred in August through October with August having the greatest
disparity of 2.63 inches. Starting off the year, snow depths varied greatly
across the region and were as much as 16 inches in the southwestern portion of
the region and as little as around 4 inches in the southeast area of the region.
Snow water equivalencies were between 2 and 4 inches of water for almost the

trace of water was left in the southern half of the region with less than an inch
remaining in the little snow that was left. By April 4th the region was snow
free. Thunderstorms on April 10 produced rainfall totals in excess of one inch
in some southeast, northwest, and north central Minnesota locations. The April 10
rainfall total for Grand Meadow (Mower County) was 2.40 inches, a state-wide
record for the date. On April 26 and 27, the same storm that spawned the
devastating tornadoes in the Gulf states generated large amounts of rain (and
some snow) in the eastern one-half of Minnesota. Totals in the region ranged
from one inch to an inch and a half. Significant flooding was reported across
Minnesota during much of the month of April. River levels reached major flood
stage along the Mississippi and St. Croix Rivers as well as their tributaries in
April. Monthly average stream flow maintained levels above the 75th percentile
through the month of August. July 2011 ranked among the ten warmest Julys in
Minnesota's modern record. The month of July was also notable for the intensity,
geographic extent, and duration of high dew point temperatures. Multiple days of
very high dew point temperatures were reported at many locations with dew point
temperatures in excess of 75 degrees. The remainder of the year was warm and dry
as the U. S. Drought Monitor, released on October 27, depicted nearly every
Minnesota county as experiencing some level of drought. The month of September
saw the second driest September on record, going back to 1882.

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site.
The ice out date was 03/04/2010.
Snowmelt conditions: 2010 started out cold with the first two months of the year
being well below average. A potent Alberta Clipper dumped several inches of snow
in the area on January 6th and 7th, while precipitation for the first quarter of
the year was within a half inch of average. The water content of the 15 inch or
more snow pack was modeled to be between two to four inches. Soil frost depths
under sod range measured from three to twelve inches due to the heavy blanket of
snow cover impeding frost penetration in spite of cold December, January, and
February temperatures. March and April showed a complete reversal with much
higher than average temperatures and below average precipitation through May
leaving all ground in Minnesota void of snow cover by April 1st and most of
Minnesota without soil frost. [source: State Climatology Office ?DNR Waters]
The stream was in its banks during the entire year. nothing noted and from cross
section info it does not appear to have been out of bank during september event.
Periods of low or no flow: periods during june july and august were low flow
Significant climatic events: . June, July, and September were above average
months for precipitation with June and September being very wet months with
averages more than three and eight inches respectively above normal. Comparing
monthly rainfall totals with previous years reveals that June precipitation
ranked above the 90th percentile over much of the southern one-third of
Minnesota, and ranked above the 95th percentile in many locales. In addition to
large totals, June rainfall was also unusually frequent in southern Minnesota.
September rainfall totals compared with other Septembers in the historical record
ranked near or above all-time high values for nearly every location in the
southern three tiers of Minnesota counties. September's heavy rainfall totals
were primarily the result of an extraordinary rainfall event that occurred on
September 22 and 23. More than six inches of rain fell over a 5000 square mile
area of southern Minnesota. Rainfall totals of more than eight inches were
reported in portions of 10 counties. The heavy rain, falling on soils already
sodden from a wet summer, led to numerous reports of major rural and urban
flooding. August and October were both warm months being 4 degrees above average
with below average precipitation. November? temperatures were several degrees
higher than average as well, but winter arrived with a vengeance on November
13-14 with a classic winter storm dumping six to ten inches. Later in the month
large snow falls of up to 10 inches fell on November 28th and by December ice was
beginning to occur in slower moving channels. Ice-in around the state occurred
in early December.

Data is collected year round at this site.
The ice out date was 03/05/2009.
Snowmelt conditions: The year began with the coldest January statewide since
1994. Winter precipitation totals were generally near average in southeast MN
following late February snowstorms. In sharp contrast with the rest of the
state, March and much of April were dry months in southeast MN. Rain events
towards the end of April decreased the precipitation shortfalls. At this site it
seems that the ice starts to break up in late February\092early March as the data
shows increases\092decreasing stages without precip. It is assumed ice out around
3/5 before peak runoff event on 3/6. JEG
The stream was in its banks during the entire year.
Periods of low or no flow: July was a dry month for 2009 - low flows at Little
Cannon were experienced in early August. August 6th and 7th brought in precip
totals around 3 inches. Low flows returned in late September. Lowest flow of

The year
began with the coldest January statewide since 1994. Winter precipitation totals
were generally near average in southeast MN following late February snowstorms.
In sharp contrast with the rest of the state, March and much of April were dry
months in southeast MN. Rain events towards the end of April decreased the
precipitation shortfalls. Monthly mean temperatures for May and June 2009 were
well below historical averages in most of the region. Significant precipitation
events in June caused sharp increases in river discharges. In contrast, July was
a dry month across nearly all of Minnesota and continued the cooler than normal
trend of the previous two months, partially slowing precipitation deficits in the
region. However, September temperatures were relatively warm and precipitation
totals were well below normal, amplifying drought conditions in the area. In
southeast Minnesota, 16-month precipitation deficits led to a significant impact
on hydrology. In contrast, October 2009 precipitation was very heavy across most
of Minnesota. Monthly precipitation totals in the southern two-thirds of the
state ranged from five to eight inches, topping historical October averages by
three to five inches. On a statewide basis, October 2009 will rank among the
wettest Octobers ever. It was also among the coldest Octobers of the modern
record, averaging four to seven degrees below historical averages across the
region, improving drought conditions. November 2009 precipitation was quite
light across most of Minnesota. Monthly precipitation totals fell short of
historical averages by one-half inch to one and one-half inches in most locales.
In contrast to a very cold October, monthly mean temperatures for November 2009
were quite mild. November mean temperatures across Minnesota ranged from nine to
twelve degrees above historical averages, making November 2009 the third warmest
November in history on a statewide basis. Ice-in occurred in late November
throughout most of the state.

Precipitation Data Summary
--------------------------------------------------------------------------------
At least three field visits were made to check the rain gage for obstructions
during the monitoring season.
There was no visual evidence or an indication from analysis of the precipitation
data that the rain gage was plugged at any time during the monitoring season.
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values.
The rain gage was not calibrated within the last three years. Calibrated rain
gage placed on the site on 4/20/07 but calibration process questionable.

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site.
The ice out date was 03/10/2008.
Snowmelt conditions: Precipitation totals were below the historical average in
most Minnesota locations. Lower than average snowfall meant that precipitation
totals finished one half inch to one inch below the March average. This continued
a pattern of below-normal snowfall that was prominent across most of Minnesota
during the past winter. Keeping with a season-long trend, monthly mean
temperatures for March 2008 were below historical averages. March temperatures
ranged from three to five degrees below normal across Minnesota.
The stream was in its banks during the entire year.
Periods of low or no flow: Mid august through the end of the year were the low
flow periods for 2008.
Significant climatic events: In January Precipitation totals were well below
historical averages across most of Minnesota. Many locations reported less than
one quarter of an inch of liquid precipitation, and less than four inches of
snow. For February Precipitation totals were below the historical average in
most Minnesota locations. Monthly mean temperatures for February 2008 were well
below historical averages. February temperatures ranged from five to seven
degrees below normal across Minnesota. In March Precipitation totals were below
the historical average in most Minnesota locations. Lower than average snowfall
meant that precipitation totals finished one half inch to one inch below the
March average. This continued a pattern of below-normal snowfall that was
prominent across most of Minnesota during the past winter. Keeping with a
season-long trend, monthly mean temperatures for March 2008 were below historical
averages. March temperatures ranged from three to five degrees below normal
across Minnesota. April brought precipitation totals were above historical
averages across nearly all of Minnesota. Precipitation totals in most northeast,
east central, and southeastern Minnesota counties topped five inches for the
month. Total April precipitation in some southeastern Minnesota locales exceeded
seven inches. May 2008 precipitation totals were near historical averages in
most Minnesota communities. Monthly mean temperatures for May 2008 were below
historical averages. May temperatures ranged from three to six degrees below
normal across Minnesota. The cool temperatures in May delayed many of the normal
signs of spring. June rainfall totals varied greatly across Minnesota. Extremely
wet conditions were reported in northeastern and southeastern Minnesota, while
below-normal precipitation totals were common in central, east central, and south
central counties. The first half of June produced numerous rounds of severe
weather and flooding in Minnesota. June mean monthly temperatures were again
below normal. July rainfall totals were short of average by one to two inches in
most locales. July mean monthly temperatures were near historical averages.
Most of Minnesota continued to experience a mid-summer dry spell. August rainfall
totals were short of average by two or more inches in most locales. September
rainfall totals were highly variable across Minnesota: short of average by one to
three inches in the south. October precipitation totals were larger than average
over much of the western one-half of Minnesota. In some west central and
northwestern Minnesota locales, October monthly precipitation totals were among
the largest in the historical October record. Monthly mean temperatures for
October 2008 were close to historical averages. Portions of Minnesota, most
notably southeastern Minnesota, remained impacted by a long-term dry spell.
Rainfall deficits in these areas were greater than five inches since mid-June.
November 2008 precipitation totals were variable across Minnesota. Monthly mean
temperatures for November 2008 were two to four degrees above historical
averages. Portions of east central and southeastern Minnesota remained in a
Moderate Drought condition. December 2008 precipitation totals were well above
average across Minnesota. The total water content of December's snowfalls topped
historical averages by one-half inch to one and one-half inches in many locales.
December 2008 was also marked by frequent, and often heavy, snowfall events.
Monthly mean temperatures for December 2008 were four to eight degrees below
historical averages across Minnesota.

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site.
Ice out determined to be around 3/10 because max temperature is above freezing for several consecutive days.
The ice out date was 03/10/2008.
Snowmelt conditions: Maximum daily temperature above freezing for the site around 3/10, minimum daily temperatures above freezing around March 25th.
The stream was in its banks during the entire year.
Periods of low or no flow: The periods of low flow were from approximately 6/25 until 8/10. There were no periods of no flow.
Significant climatic events: 2007 started out with warmer than normal temperatures in mid March. Warm temperatures were reported through May where the Rochester area reported its 5th warmest month of May. Topsoil moisture depths were reported as very shallow for the month of July causing watersheds to remain very low in some areas including the Rochester area. Duel climatic disasters occurred in August. The USDA declared 24 Minnesota Counties to be in severe drought and eligible for federal assistance, and FEMA declared 7 southeastern Minnesota Counties to be flood disasters and eligible for federal assistance as well. The Rochester area reported around fourteen inches of rainfall in August. (Sources are Mark Seeley's Weather Talk for 2007)

Flow Data Summary
--------------------------------------------------------------------------------
Site vists to determine if the logger was tracking stage correctly were done at a frequency of 8 weeks or less.
Stage tracked correctly during the entire monitoring season. Only minor adjustments made to stage entire year.
Other stage data collection factors: Orifice line unplugged on 3/21. Rain bucket replaced on 4/20.
8 flow measurements were taken during the monitoring season.
All recorded stage values were within the rating or less than 1 foot above the rating with no change in channel control.
Flow measurements were taken with a maximum frequency of 4-5 weeks or with a frequency that accurately reflects seasonal conditions.
Flow measurements cover a wide range of flows, up to at least 70% of the highest recorded seasonal/annual discharge.
The rating is well developed when considering both quality and quantity of measurements.
Site vists to determine if the physical characteristics of the control changed during the monitoring season were done at a frequency of 5 weeks or less.

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site. but winter ice data is not used.
it is approximated using temperature data and cont. data hydrograph.
The ice out date was 01/18/2007. 02/24/2006 was used as ice out. Some shore ice remained at this time but water pretty much open.
Snowmelt conditions: NA
Periods the stream was out of its banks: I don not know.
Periods of low or no flow: from late august to end of season low flows were taken.
Significant climatic events: This is a part of Dr. Mark Seeley's (the University of Minnesota) prepared annual climate synopsis for 2006.
Drought left its mark on Minnesota during 2006 and much of the state remains in its grasp, as central and northern counties are still marked as Severe to Extreme Drought by the USDA and National Weather Service. Lake levels are very low, including Lake Superior, river flows are low, and stored soil moisture in many areas is the lowest since the drought of 1988 in some areas.

Flow Data Summary
--------------------------------------------------------------------------------
Stage did not track correctly during the entire monitoring season. there is some variable data from 5-20 to 8-24. Oriface appears to be slightly plugged so some stage variability is present. Gage does track correctly over this time, but with some variability.
Stage tracked correctly during all moderate to high flow periods.
Missing stage values were accurately estimated or interpolated using a technique that introduced less than 5% error.
Other stage data collection factors: oriface line appeared to be slightly plugged from 5-20 to 8-24 2006. Slight variability present in 15 minute data during this time.
9 flow measurements were taken during the monitoring season. 9
Some recorded stage values were greater than 1 foot above the rating and/or encountered a change in control. The rating was extended to cover this new high flow.
The present rating can be accurately extrapolated or modeled to the highest recorded stage values.
Flow measurements were taken with a maximum frequency of 4-5 weeks or with a frequency that accurately reflects seasonal conditions.
Flow measurements cover a wide range of flows, up to at least 80% of the highest recorded seasonal/annual discharge.
The rating is well developed when considering both quality and quantity of measurements.
No change in the physical characteristics of the control occurred during the monitoring season.
