YEAR END SUMMARY
STATION NAME: Big Sucker Creek nr Palmers, CR258
STATION NUMBER: H02031002
YEAR: 2021
PREPARED BY: Jacob Mickelson, jacob.mickelson@state.mn.us

CLIMATE SUMMARY:
Division 3, 2021: After a generally mild winter with below-normal snowfall, warm and dry conditions dominated the May-through-October liquid precipitation season, leading to widespread Extreme drought categorizations on the US Drought Monitor. Precipitation from May through October averaged about 63% of normal. May through July was the driest on record back to 1895, with an average of under 5.0 inches of rain falling over the 3-month period (normal would have been over 11 inches). June and July had bouts of extreme heat, which worsened the drought conditions, and May through October averaged over 4.0 degrees F above normal and was the warmest on record. Normal and above-normal precipitation during late summer and autumn helped drought conditions improve, although deficits remained. No significant precipitation events occurred. Mean temperatures fell below freezing in early November, and the seasonal snow pack formed during mid-November in far northern areas, and by early December elsewhere.

STATION OPERATION SUMMARY:
This station operates year-round, but precipitation is only monitored during the liquid precipitation season.
Is this site monitored year round? YES
Open water dates - estimated Ice out and Ice in: Ice out is 04/01/2021. Ice in is 11/15/2021.
Summary of equipment - related factors that impacted data collection: No equipment related isssues occurred during the season outside of minor orifice line freezing.

DISCHARGE SUMMARY:
Number of flow measurements for monitoring season: 8
Was the full range of flows measured for the season? NO, highest measured discharge in 2021 was 201 cfs on 3/25/2021 while highest calculated discharge was 379 cfs on 4/12/2021 representing only 53% of flow. Low and moderate flows for 2021 were well represented.
Was a new rating developed? NO
General summary of control changes/shifts needed: Ice impacts were shifted for periods with ice coverage. Control remained clear until early fall when leaf litter accumulated in stream and on riffle. That impact was seen until ice again formed on stream.
Quality of computed daily discharges: Outside of ice, the majority of the year coded fair and poor due to low flows. Late August saw estimated qualities due to falling into an unsupported area of the rating curve. Also, a few days in Spring coded good during moderate flows.

PRECIPITATION DATA OVERVIEW:
Was precipitation data collected at this site? YES
Climatological liquid precipitation period: 05/01/2021-10/31/2021
Was there a complete and acceptable precipitation record for this period? YES, no observed blockages occurred during the liquid precipitation year. Rain bucket tracked slightly high but approved by state climatology office.

YEAR END SUMMARY
STATION NAME: Big Sucker Creek nr Palmers, CR258
STATION NUMBER: H02031002
YEAR:2020
PREPARED BY: Jacob Mickelson; jacob.mickelson@state.mn.us

CLIMATE SUMMARY:
Division 3, 2020: Mild conditions and near-normal snowfall January through into April topped off a moderately snowy early winter, leading to normal to above-normal seasonal snowfall totals of 55-85 inches along the lakeshore and across the Iron Range, with totals of 85 to 135 inches in interior highlands and uplands running parallel to Lake Superior. The May-September growing season was relatively warm and dry, punctuated by significant June through August warmth, and by 50-70% precipitation deficits in May, June and September. The region saw no excessive rainfall events. Temperatures fell deeply below freezing in early October, but with little precipitation falling, the liquid precipitation season extended to October 15. Snow fell several times beginning mid-October, and into early November, with 15-25 inches common by the end of November. Extreme warmth melted much of the snow during early-mid November, but by December 1, most of the climate division had snow on the ground, with depths of up to 6 inches in the higher terrain inland from Lake Superior.

STATION OPERATION SUMMARY:
Is this site monitored year round? YES
Open water dates - estimated Ice out and Ice in: 4/16/2020-11/13/2020 with an early fall freeze up 10/26/2020-11/02/2020 before eventually going ice free for 11 more days.
Summary of equipment - related factors that impacted data collection: No equipment related factors impacted data collection. There was a brief period of time when winter discharges were smoothed.

DISCHARGE SUMMARY:
Number of flow measurements for monitoring season: 7
Was the full range of flows measured for the season? NO, only low flows were measured during the 2020 season.
Was a new rating developed? YES, rating 4.0 developed to incorporate a scour seen at low flows since 2019.
General summary of control changes/shifts needed: Outside of winter ice impacting control, the only control change was in October when leaf litter was caught across the riffle.
Quality of computed daily discharges: Ice codes persist in winter and also during a late October cold snap. The majority of the year coded fair with a few days coding poor and a couple days coded good.

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? Yes

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.

Climate Summary
--------------------------------------------------------------------------------
Data is collected year round at this site.
The ice out date was 04/10/2016. There was a variable ice out due to numerous
freeze and thaw periods with a mix of rain and big snow events.
Snowmelt conditions: Several freeze thaw periods from the end of February
through early to mid April with temps from 40 to 60 degrees F during the thaw
periods. There was about 1 ft or more of snow in early March that was down to 6
inches or less around mid March and then an additional 4 to 6 inches fell the
16th and 17th of March and began melting around March 21st. Snow depth was down
to a trace by March 22nd. Another round of 4 to 6 inches of snow fell on March
26th and was around until March 30th. Another 6 to 8 inches fell around April 5th
and was gone by April 15th. Streams were opening up in early to mid March, but
weren't free of ice until late March or early to mid April.
Periods the stream was out of its banks: Cross section survey determined bank
full to be around 80.37 ft on the right bank as the left bank is incised and
would need to be 81.37 ft on the left bank before it would top the edge. Stage
were at our out of banks on 03/11/16 to 03/20/16, 03/30/16 to 03/31/16, 05/15/16
to 05/18/16, 05/25/16 to15/27/16, 06/13/16 to 06/17/16, 07/12/16 to 07/13/16, and
11/28/16 to 11/30/16.
Periods of low or no flow: Flows were at or below 10 cfs from 01/18/16 to
03/07/16 when ice was present and from 08/17/16 to 08/28/16 during open water
conditions.

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: No equipment problems other than the wire
weight had to be fixed after it had been dropped.
13 flow measurements were taken during the monitoring season. Ice affected 4 of
the measurements and the rest were open water method.
All recorded stage values were within the rating or less than 1 foot above the
rating with no change in channel control. The highest open water logged stage
for 2016 was 81.58 ft and occurred on 06/16/16. The stage of the highest historic
discharge measurement occurred on 11/18/15 and was 80.87 ft. The highest gaged
stage for this monitoring season was 80.44 ft measured on 11/30/16. The out of
banks stage is at approximately 80.37 ft, so there's no change in control as all
of these stages were above bankfull.
Flow measurements were taken this year with a maximum frequency of 4-5 weeks or
with a frequency that accurately reflects seasonal conditions. The September to
November measurement was a couple days over 5 weeks.
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 recorded 15 minute discharge for 2016 was 458 cfs on
06/16/16. The highest gaged measurement was 207 cfs on 11/30/16 for 45% of the
flow for 2016.
This is a stable site. Rock riffle that appears to be fairly stable. Sitll a new
site, so there's some uncertainty in the rating.
The rating is not well developed over this year's range of flows when considering
quality and quantity of measurements. Still need more clear measurements
above79.56 ft or 45 cfs and below 79.20 ft or 12.3 cfs. This is new site with
only 3 years of data, so as time goes on this rating should improve and become
well developed. The rating had to be extended to account for high stages during
ice out and again in June.
The rating has at least five measurements over the full range of this year's
flows. Range of flows for 2016 was 5.3 cfs to 458 cfs and measurements ranged
from 9.8 cfs to 207 cfs. Stage in June were only 0.3 ft higher than the highest
rating point from the previous rating, but had to be extended higher for ice
affected stages in March.
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. Ice affected the control and debris affected
stages just below bank full.
Change in control: Ice was present through the middle of March. There were
several freeze and thaw periods from the middle of March into early April with
numerous snow events through that time period affecting the control. Stages from
later March through April were affected by debris on the edges for stages just
below bank full. Ice impacted the control again in early to the middle of
December.
Adequate flow measurements were taken to confidently adjust stage during
period(s) of altered control. Measurements were taken often enough to accurately
document the change in control.

Precipitation Data Summary
--------------------------------------------------------------------------------
The precipitation record tracked correctly and was complete for the monitoring
season. Frozen precipitation data was removed from the record. The site 22.15
inches of precipitation compared to 23.91 inches at the nearby Hiden for 93% of
the total.
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.
The bucket was noted to be clear all year.
There were no vertical obstructions near the rain gage that may have compromised
recorded rainfall values. Trees are in the area, but don't affect the rain
bucket.
The rain gage was calibrated within the last three years. The bucket was
installed in October of 2014.

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 affected by ice for most of the
winter and protions of data throughout the winter was deleted due to frozen
orifice line especially from 03/09/15 to 03/30/15.
Stage was accurate and complete during all moderate to high flow periods this
season. Stages were high during March, but that was flow over ice as there was
still several feet of ice and the orifice line was affected or frozen during this
time.
Incorrect or missing stage values were accurately adjusted or estimated using a
technique that introduced less than 5% error in total seasonal flow volume. Ice
affected stages were not estimated due to frozen orifice line. Flows were
estimated based on available inspections and looking at the USGS E02026001 site.
Total of average daily flows from 01/01/15 through to ice out on 04/09/15 were
515 cfs. The total for 2015 was 11,745 cfs for 4.4% of the flow being estimated
due to ice affects and/or frozen orifice line.
Other stage data collection factors: Wire weight gage was found to be off by
0.03 ft from May to August. Wire weight reset back to 100.00 ft from 99.97 ft on
08/12/15. Measure stage were offset and logger data was properly adjust.
11 flow measurements were taken during the monitoring season. Ice affected 3
measurements from January to March and another in December for a total fo 4 ice
measurements.
All recorded stage values were within the rating or less than 1 foot above the
rating with no change in channel control. The highest open water logged stage
for 2015 occurred on 09/24/15 and was 81.21 ft. The stage of the highest historic
discharge measurement occurred on 11/18/15 and was 80.87 ft. The highest gaged
stage for this monitoring season was 80.87 ft measured on 11/18/15. The out of
banks stage is at approximately 80.37 ft, so there's no change in control as all
of these stages were above bankfull.
Flow measurements were taken this year with a maximum frequency of 4-5 weeks or
with a frequency that accurately reflects seasonal conditions. This is a year
round site and it was gaged every 4-5 weeks.
Flow measurements cover a wide range of flows, up to at least 70% of the highest
recorded seasonal/annual discharge. The highest recorded 15 minute discharge for
2015 was 378 cfs on 09/24/15. The highest gaged measurement was 289 cfs on
11/18/15 for 76% of the flow for 2015.
The rating is not well developed over this year's range of flows when considering
quality and quantity of measurements. More clear measurements are needed
above79.56 ft or 45 cfs and below 79.20 ft or 12.3 cfs. This is new site with
only 2 years of data, so as time goes on this rating should improve and become
well developed.
The rating has at least five measurements over the full range of this year's
flows. Range of flows for 2015 was 2.06 cfs to 378 cfs and measurements ranged
from 2.21 cfs to 289 cfs for a total of 76% of the 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. Ice affected the control; as well as, vegetation
and/or debris also affected the control.
Change in control: Ice affected the control from January through ice out on
04/09/15. A very long duration cold snap allowed most of the channel to freeze
almost to the bottom with very little flow left in March. A tree from upstream
flowed down and got stuck between our gage and the riffle in July and began
affecting our stages in August with algae also noted on the riffle.
Adequate flow measurements were taken to confidently adjust stage during
period(s) of altered control. Measurements were taken often enough to accurately
document the change in control.

Precipitation Data Summary
--------------------------------------------------------------------------------
The precipitation record tracked correctly and was complete for the monitoring
season. The site reported 23.22 inches compared to 25.1 inches at the nearby
Hiden for 92.5% reporting rate and 25.8 inches at the Duluth Airport. The bucket
was not blocked nor was it affected by trees within the catchment area. The rain
bucket was newly installed in 2014,
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. The rain bucket was
newly installed in 2014,

Climate Summary
--------------------------------------------------------------------------------
Data is only collected for a partial year at this site. Gage was moved from old
location H02031001 that had been wiped out during the 2012 flood.
Data collection began on 10/02/2015. Moved from the old location H02031001
downstream.
Data collection ended on 12/31/2015.
The ice out date cannot be determined. Gage moved from old site H02031001 on
10/02/14.
Snowmelt conditions: The bulk of the snomelt likely occured between 04/20/14 and
04/24/14 based on the old site H02031001.
The stream was in its banks during the entire year. Gage moved on 10/02/14, so
no stage was over bankfull of 80.37 ft on the right bank as the left bank is
incised and would need to be 81.37 ft on the left bank before it would top the
edge.
There were no periods of low or no flow during the entire year. Gage moved on
10/02/14 with flows higher than10 cfs as in July and August at the previous site
H02031001.

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 bubbler line was loose and not giving the
proper stage the first week after install.
Stage either did not track correctly or was not complete during some or all
moderate to high flow periods this season. The gage was installed on 10/02/14,
after the high flows for the year. Data estimated from install on 10/02 to 10/08
due to bubbler problems using the nearby Knife gage E02026001.
Incorrect or missing stage values were accurately adjusted or estimated using a
technique that introduced less than 15% error in total seasonal flow volume.
Data estimated from install on 10/02 to 10/08 using the nearby Knife gage
E02026001.
Other stage data collection factors: The bubbler line was loose and not giving
the proper stage the first week after install.
6 flow measurements were taken during the monitoring season. Ice measurements in
November and December.
All recorded stage values were within the rating or less than 1 foot above the
rating with no change in channel control. The highest open water logged stage
for 2014 occurred on 10/02/14 and was 79.44 ft at install of the gage at the new
site. The stage of the highest historic discharge measurement occurred on
06/17/14 and was 79.69 ft before the gage was moved to the new site. The highest
open water gaged stage for this monitoring season was 79.69 ft measured on
06/17/14. The out of banks stage is at approximately 80.37 ft, so there's no
change in control as the highest logged stage and historic measurement were below
bankfull stage.
Flow measurements were taken this year with a maximum frequency of 4-5 weeks or
with a frequency that accurately reflects seasonal conditions. Gage was moved to
new location on 10/02/14.
Flow measurements cover a wide range of flows, up to at least 70% of the highest
recorded seasonal/annual discharge. The highest recorded 15 minute discharge for
2015 was 17.8 cfs on 10/12/14. The highest gaged measurement was 71.5 cfs on
06/17/14 for 400% of the flow for 2014.
The rating is not well developed over this year's range of flows when considering
quality and quantity of measurements. Gage moved to new location and was only a
partial year of flows occuring late in the year. More measurements are needed
above 71 cfs and below 12 cfs.
The rating has less than 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. Gage
moved late in the year and only a couple measurements occured before ice in, so
control changes were documented for the period of record.
No change in the physical characteristics of the control occurred during the
monitoring season. No shifts for open water were needed after the gage was moved
on 10/02 to the new location. Only shifted for ice starting in November
condinued through December.

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

installed on 10/02/14.
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. New rain bucket on
install.
