Year End Summary for 2022
YEAR END SUMMARY STATION NAME: Rabbit River at Campbell, CR4 STATION NUMBER: H54017001 YEAR: 2022 PREPARED BY: Colten VanZee (colten.vanzee@state.mn.us) CLIMATE SUMMARY: 2022 - Division 4: The first four months of the year were very cold, with temperatures averaging more than 5^ F lower 1991-2020 normals. Precipitation was near normal during this period. during this time. May was rather wet, but very dry conditions in June, July, and September, left the May-September precipitation season an average of 3.5 inches and 20% drier than normal, with temperatures about 1.6^ F above normal. Several outbreaks of severe convective storms affected the area in May and June, but there were no major rainfall or flash-flooding episodes during the precipitation season. A major storm December 13-17 dropped 4 to 14 inches of snow containing 0.75 to 1.5 inches of water equivalent. Additional snows the following week led to a deep snowpack for the end of December, with 8 to 15 inches on the ground in most areas, ranking between the 80th and 99th percentile for this time of year. STATION OPERATION SUMMARY: Is this site monitored year round? No Open water dates - estimated Ice out and Ice in: Estimated ice out on 3/22/22, unable to determine ice due to lack of data. Open water sites ONLY. Period of data record (if different from ice out/ice in dates): 3/17/22 to 11/1/22 Summary of equipment - related factors that impacted data collection: The orifice line was out of water on 3/30 and 3/31/22. During this period data was estimated. The gauge was then removed on 7/19/22. Data from the downstream Rabbit River (H54017002) location was used to help estimate daily discharges from 7/19/22 to 11/1/22. DISCHARGE SUMMARY: Number of flow measurements for monitoring season: 4 Was the full range of flows measured for the season? No, the major peaks of the season were missed. Highest measured discharge was collected on 3/22/22 at 1358cfs, highest calculated discharge was 2594 5/31/22 event. Lowest measured discharge at this location was on 7/19/22 when the gauge was removed but it is estimated that this site had zero flow or near zero flow starting on 9/9/22. Was a new rating developed? No General summary of control changes/shifts needed: Debris and ice likely impacted the channel at the start of the season. Debris impacted the channel again starting in June through the remainder of the record. Quality of computed daily discharges: Estimated, questionable and poor. PRECIPITATION DATA OVERVIEW: Was precipitation data collected at this site? YES Climatological liquid precipitation period: 5/1/22 to 10/1/22 Was there a complete and acceptable precipitation record for this period? No, the rainbucket tracked well throughout the monitoring season except for on July 16th where it experienced a potential blockage and under-reported. This day was removed per the recommendation of the state climate office.
