YEAR END SUMMARY
STATION NAME: North Fork Whitewater River at Elba, Whitewater Dr
STATION NUMBER: H40017002
YEAR: 2021
PREPARED BY: Jacob Kolke; jacob.kolke@state.mn.us

CLIMATE SUMMARY: Division 9, 2021: After a generally mild winter with normal to below-normal snowfall, warm and dry conditions persisted during the May-through-October liquid precipitation season, leading to some drought designations. Precipitation from May through October averaged about 85% of normal, or just under 4 inches below normal. May through July was dry, with an average of just under 11 inches of rain falling over the 3-month period (normal would have been just under 14.5 inches). June had bouts of extreme heat, and May through October averaged just 2.5 degrees F above normal. Normal to above-normal precipitation during late summer and autumn helped drought conditions improve, and areas near the Mississippi River spent little time in official drought designations. Heavy rain fell on August 26-27, with 3-5 inches in many areas. Mean temperatures fell below freezing in early November, with accumulating snows most areas by early December.

STATION OPERATION SUMMARY:
Is this site monitored year round? NO
Open water dates - estimated Ice out and Ice in: 2/22/2021 - 12/6/2021
Period of data record: 3/2/2021 - 11/18/2021
Summary of equipment - related factors that impacted data collection: There were no recorded equipment issues that impacted data collection for the season.

DISCHARGE SUMMARY:
Number of flow measurements for monitoring season: Seven. All were open water measurements.
Was the full range of flows measured for the season? NO. Measured flows ranged from 45.9 to 57.2 cfs while the calculated flows ranged from 43.6 to 236 cfs.
Was a new rating developed? YES. New rating made to account for new low level deposition measured throughout the monitoring season. A regression was used to re-shape low-moderate end of rating. All 2021 measurements except for the March measurement fell on the new rating. No changes to middle or upper end of rating.
General summary of control changes/shifts needed: A minor amount of deposition occurred at the start of the monitoring season and lasted up to the snowmelt events in early March. No other control changes/shifts were needed.
Quality of computed daily discharges: Most of the year was coded poor. A handful of low flow days in the late summer were coded estimated.

YEAR END SUMMARY

STATION NAME: North Fork Whitewater River at Elba, Whitewater Dr
STATION NUMBER: H40017002
YEAR: 2020
PREPARED BY: Jacob Kolke; jacob.kolke@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 occured on 3/2/2020 while ice in was on 12/14/2020.
Open water sites ONLY. Period of data record (if different from ice out/ice in dates): 3/8/2020 - 11/11/2020
Summary of equipment - related factors that impacted data collection: The bubbler line became damaged during the high flow event in late May and collected extremely spikey data until it was fixed in late July. Data was smoothed in the record. No other issues impacting data collection were noted.

DISCHARGE SUMMARY:
Number of flow measurements for monitoring season: Four. All were open water measurements.
Was the full range of flows measured for the season? NO. Measured flows ranged from 86 to 167 cfs while the calculated flows ranged from 78 to 1,150 cfs.
Was a new rating developed? NO
General summary of control changes/shifts needed: Scour impacted flows starting in mid-March and lasting until late May. The high flow event in late May brought in deposition and debris that impacted the control in varying amounts through late August.
Quality of computed daily discharges: All but one day is coded estimated due to COVID 19 policy and low flows. The one day not coded estimated is coded poor.

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this site? YES
Climatological liquid precipitation period: 4/16/2020 - 10/15/2020
Was there a complete and acceptable precipitation record for this period? NO. Data for 4/16/2020 was removed. SCO determined recorded precip on that day was actually a snowmelt 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: North Fork Whitewater River at Elba, Whitewater Dr
STATION NUMBER: H40017002
YEAR: 2019
PREPARED BY: Jacob Kolke (jacob.kolke@state.mn.us)

CLIMATE SUMMARY: Division 9, 2019: 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: 3/14/2019 - 12/10/2019
Period of data record: 3/13/2019 - 11/19/2019

Summary of equipment - related factors that impacted data collection: There was some impact from a downed tree that affected the level recordings and the wire weight gage readings during the middle of the monitoring season. The data that was collected tracked fairly well, but the logger required more resets compared to past seasons.
Number of flow measurements for monitoring season: 8
Was the full range of flows measured for the season? NO. The highest calculated flow was 3,978 cfs on 3/14/2019. The highest gaged flow was 275 cfs taken on 7/1/2019. Only 7% of the highest flows were gaged for the monitoring season.

DISCHARGE SUMMARY:
Was a new rating developed? YES. New rating made for 2019 season. Measurements had a strong scour trend compared to the previous rating. Lower and middle sections were shifted to match up with a regression using the 2019 measurements and 2017 high flow measurement.
General summary of control changes/shifts needed: There was one brief period of ice impacted data where the spring melt and runoff events rose and water flowed through the snow on the banks. This lasted for the first week of the season in mid-March, but didn't appear to affect the flows.
Quality of computed daily discharges: The vast majority of the daily flows were poor. There were also a good amount of estimated values. A few days were coded ice, two days were coded questionable, and two other days were coded unreliable.

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this site? YES
Climatological liquid precipitation period: 5/1/2019 - 10/31/2019
Was there a complete and acceptable precipitation record for this period? YES

Year End Summary for 2018

YEAR END SUMMARY
STATION NAME: North Fork Whitewater River at Elba, Whitewater Dr
STATION NUMBER: H40017002
YEAR: 2018
PREPARED BY: Jacob Kolke, jacob.kolke@state.mn.us

CLIMATE SUMMARY: Division 9, 2018: A long and late winter produced frozen precipitation and cold conditions well into April, with snow cover persisting until the final week of the month. The May - September growing season was very warm and very wet, averaging 3.1 degrees F warmer and 6.1 inches (or about 28%) wetter than 1981-2010 averages. An extreme rainfall event with 6-8-inch totals affected the Root River area on August 28, with a slightly smaller event producing 4-6-inch totals and flooding in southeastern Minnesota on September 5. Other heavy rain events produced 2-4-inch totals on June 9-10, June 17, July 1, and September 20-21. In extreme southeastern Minnesota, Harmony set Minnesota's annual precipitation record. Cool weather resumed in early October, with snows on the 14th, and the seasonal snow cover beginning around December 1.

GAGE OPERATION SUMMARY:
Is this site monitored year round? NO
Open water dates: 2/22/2018 - 11/6/2018
Summary of equipment-related factors that impacted data collection: There was a brief period where the o-line was buried at the start of the season. This slightly impacted the data until early March when it was fixed. There were no other factors that impacted data collection for the monitoring season.
Number of flow measurements for monitoring season: 8
Was the full range of flows measured for the season? NO. The highest gaged level was 36.65 ft with a measured flow of 138 cfs. The highest recorded level for the season was 38.4 ft with a rated discharge of 477 cfs. Only 28.9% of the max seasonal flow was measured.

DISCHARGE SUMMARY:
Was a new rating developed? YES. Measurements from mid to late 2018 had a strong scour trend compared to the old rating. Moved rating downward to intersect as many measurements as possible while still leaving the rating at higher levels untouched. Smoothed the rating between the lower changed levels and the higher unchanged levels to ease the transition between the two.
General summary of control changes/shifts needed: Starting the season there was a period of scour that occurred and lasted until mid to late March. This transitioned to a period of deposition that impacted the control until mid-April. After that, there was a short scour event that only affected the control starting in mid September and lasted until mid October.
Quality of computed daily discharges: All daily discharge data is poor due to the new rating.

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this site? YES
Climatological liquid precipitation period: 5/1/2018 - 10/13/2018
Was there a complete and acceptable record for this period? NO. The month of August was removed from the record per direction of the State Climatology Office. Bucket recorded less than the acceptable climatological minimum total for the month.

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 tracked correctly and was complete for the entire monitoring
season. visits were made 2/16 through 11/21
Other stage data collection factors: logger was reset 2x due to sediment in
O-line
11 flow measurements were taken during the monitoring season. 2/23 - 10/19
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. Rating had to be extended
1.06 ft to encompass the highest flows ever recorded at the site.
The present rating can be accurately extrapolated or modeled to the highest
recorded stage values. The rating was extrapolated off of the modeled points for
the rating.
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 up to or above 15% of the highest recorded season/annual
discharge. The highest gaged flow was taken on 5/16/17 and had a discharge of
1259.6 cfs. The highest recorded stage was during the event on 5/16/17 and had a
computed discharge of 4193.7 cfs. Therefore the measurements were within 30% of
the highest recorded annual discharge.
This is not a stable site. After a large event in May, the channel
characteristics changed requiring a whole new rating.
The rating is not well developed over this year's range of flows when considering
quality and quantity of measurements. The highest events needed modeled points.
The rating has at least five measurements over the full range of this year's
flows.
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: There was a period of scour affecting the control just after
ice out in mid February through early March. A large scour event in mid May
caused extreme changes in the channel characteristics resulting in a new rating.
After that event in mid May, a second period of scour affected the control into
early August.
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
season. climatatology data = 35.02", site data = 38.38." 100% of data from
precip season was accepted
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.
all inspections noted as clear
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values.
The rain gage was calibrated within the last three years. Installed new bucket on 8/23/18. Calibrated to 2 in/hr.

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 tracked correctly and was complete for the entire monitoring
season.
Other stage data collection factors: There were no recorded problems with the
gage.
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. The highest recorded stage for 2016
was on 8/11/16 at 39.69 ft. The highest historic discharge measurement was on
4/10/13 at 39.25 ft. The out of banks stage is at approximately 45 ft, so the
control is likely the same for both as the max stage for 2016 is only 0.5 ft
higher than the max gaged flow.
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 up to or above 40% of the highest recorded season/annual
discharge. The highest gaged stage was 37.965' on 9/22/16 and had a discharge of
347.697 cfs. The highest recorded stage was 39.69' on 8/11/16 and had a computed
discharge of 852.0 cfs. Therefore the measurements were within 40.1% of the
highest recorded annual discharge.
This is a stable site.
The rating is well developed over this year's range of flows when considering
both quality and quantity of measurements.
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: There was a period of bank veg growth that affected the high
flows in mid August and late September.
Adequate flow measurements were taken to confidently adjust stage during
period(s) of altered control.

corresponding discharge of 270.6 cfs. Therefore the measurements were within 93%
of the highest recorded annual discharge.
The rating is well developed over this year's range of flows when considering
both quality and quantity of measurements.  
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.  
No change in the physical characteristics of the control occurred during the
monitoring season.  


Precipitation Data Summary

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site.
The ice out date was 03/09/2014.
Snowmelt conditions: Snow depth reached a peak on 03/04/2014 of 25 inches in
Rochester, and consistantly melted until the end of the month. Snow depth was
around 19 inches during ice ut on 3/9/2014. .26 inches of rain fell on 3/11/2014.

Periods the stream was out of its banks: The stream could have been out of its
bank during a peak flow event on 6/17/2014. The stage was similar to peaks in
2013 where the river was said to 'be into its banks' There is no cross section
or inspection information to confirm this though.
There were no periods of low or no flow during the entire year.

Flow Data Summary
--------------------------------------------------------------------------------
Site vists 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. The logger was down from 3/26/14 - 4/03/2014.
The data was estimated using a nearby site as reference.
Stage either did not track correctly or was not complete during some or all
moderate to high flow periods this season. There were two rain events that
caused a rise in stage during the time the gage was down. These were estimated
using the inspections made during that time and a nearby site.
Incorrect or missing stage values were accurately adjusted or estimated using a
technique that introduced less than 15% error in total seasonal flow volume.
Total annual flow = 1807413 cfs Estimated flow while logger is down = 177535 cfs
which is well under 15% of the total seasonal flow volume.
Other stage data collection factors: No other factors found
7 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. Stages were significantly
above flow measurements. A modeled rating was developed to account for this.
The present rating can be accurately extrapolated or modeled to the highest
recorded stage values. A HECRAS model was used built off of Cross-section
surveys by DNR crews, flow measurements and LIDAR data
Flow measurements were taken this year with a frequency greater than 4-5 weeks
and do not accurately reflect seasonal conditions. high flows were missed
This site does not have a permanent fixed type control structure. No permanent
structure at this site
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). Highest flow
recorded is 2163 cfs on 6/17/2014, Highest measured flow is 101 cfs on 4/3/14
which is 5% of the highest flow
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.
Between the DNR and partners there was a site visit at least once every 5 weeks
No change in the physical characteristics of the control occurred during the
monitoring season.

Precipitation Data Summary
--------------------------------------------------------------------------------
The precipitation record tracked correctly and was complete for the monitoring
season. Gage was down for s few days in March, but March was a partial month,
and April still tracked well with climatology data.
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 calibrated within the last three years. Installed Oct. 2012

The ice out date was 02/24/2013. based on climatology data
Snowmelt conditions: Snowmelt accompanied by heavy precip in april and snowfall
May 1 - 3.
Periods the stream was out of its banks: 3/31/2013 PCA inspection indicates
"water into its banks"; 4/10/2013 DNR inspection "flow into dead veg on banks"
and there were three peaks on 3/31, 4/4, and 4/10 that reached 3-4 ft higher than
these inspections. While there are no inspections or cross-section to confirm
this, it is likely the river could have been out of its banks during those
events.
Periods of low or no flow: Lower flows start in august and continue through the
end of the year with some exceptions during storm events.

For
many southeast Minnesota counties, April precipitation totals topped the
long-term average by more than three inches, erasing drought concerns in those
areas. May precipitation totals were well above historical averages in many
Minnesota counties, especially in southeast Minnesota. For many southeast
Minnesota communities, monthly precipitation totals topped the long-term average
by more than four inches, and in some cases, by more than eight inches. The most
notable weather event of the month was a historic May snowstorm that deposited
over one foot of snow on portions of southeast and south central Minnesota on May
1 through May 3. A 24-hour snowfall measurement of 15.4 inches at Dodge Center on
the morning of May 2 was the largest one-day May snow total ever recorded in
Minnesota. June rainfall totals were well above historical averages in most
Minnesota counties. A handful of southeast and south central Minnesota locations
set new all-time high records for June rainfall. April-through-June
precipitation totals in some southeast Minnesota counties were in excess of 24
inches, exceeding the historical average by an astounding 12 or more inches. For
much of southeast Minnesota, precipitation totals for April-through-June
approached, or broke, all-time highs for the three-month period. For Rochester,
it was the record wettest first half of the calendar year. October rainfall
totals were above historical averages in most Minnesota counties, especially
central and southeast sections of the state. In some communities, October
precipitation totals topped historical averages by two or more inches and eased
drought concerns. The heaviest rainfall event of October occurred on the 4th and
5th when a fall storm dropped two to six inches of rain on portions of southeast
Minnesota. Heavy downpours led to mudslides, road washouts, and urban flooding in
some communities.

Flow Data Summary
--------------------------------------------------------------------------------
Site vists to determine if the logger was tracking stage correctly were done at a
frequency of 8 weeks or less.
The stage record tracked correctly and was complete for the entire monitoring
season. Visits were made 2/26 - 11/19
Other stage data collection factors: During spring there were a few inspections
where the logger was not tracking with GH. These were inspections done on the
slopes of precip events. Turbulence and climate may have been the reason.
8 flow measurements were taken during the monitoring season. 3/6 - 10/16
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. 2013 was first year for
data collection, no rating had been developed. Although highest recorded flow is
2157 cfs on 4/42013 and highest measured flow is 809 cfs on 4/10/2013
The present rating can be accurately extrapolated or modeled to the highest
recorded stage values. A HEC-RES model was used based off of cross-sections by
DNR crew, flow msmnts, and LIDAR data
Flow measurements were taken this year with a frequency greater than 4-5 weeks
and do not accurately reflect seasonal conditions. High flows were missed
This site does not have a permanent fixed type control structure. Rock riffle
control at low flows and bridge structure/channel at high flows
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 maximum frequency of 7 weeks, up to or above
moderate to low flow levels (25% of maximum seasonal discharge). Flows were
taken at least every 7 weeks, but highest recorded flow is 2157 cfs on 4/4/2013.
Highest measured flow is 809 cfs on 4/10/13. 37.5% of the highest recorded flow
This is a stable site. Low flow channel control is rock riffle. Higher flow
control is bridge structure
The rating is not well developed over this year's range of flows when considering
quality and quantity of measurements. There needs to be more msmnts collected
for better rating development. There are no measurements made at high flows.
Modeling needed for this site.
The rating has less than five measurements over the full range of this year's
flows.
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.
Between the DNR and its partners there was a visit at least once every 5 weeks
A change in the physical characteristics of the control occurred at some time
during the monitoring season.
Change in control: Scour present at the 3/6/13 msmt. Debris build up seen for
10/16/13 msmnt. Out of bank flow during April high flows
Adequate flow measurements were taken to confidently adjust stage during
period(s) of altered control.

Precipitation Data Summary
--------------------------------------------------------------------------------

record.
Data were removed from May 2-4 when a late season cold spell and snow
event brought 9.4" of snow at this location.
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.
3/6 inspection indicated bucket was blocked with snow, but that was before
monitoring season.
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values. Nothing indicated in inspections
The rain gage was calibrated within the last three years. Installed in Oct. 2012

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.
