A targeted survey of Tadd & Upper was conducted with standard survey trapnets during late-April and single frame 1/2-inch mesh trapnets in mid-September of 2025. A targeted survey is generally used for sampling a specific kind of fish or time of year (i.e., spawning season, fall season, etc.) unlike a standard survey which samples a wider range of fish species during the summer months using standard methodology (i.e., standard time of year, set sampling stations, taking water clarity readings and oxygen/temperature profiles, etc.) and gears (i.e., lake survey gillnets, trapnets and possibly spring electrofishing for Largemouth Bass). A partial summerkill (i.e., Channel Catfish, Northern Pike, Largemouth Bass, Yellow Perch, Sunfish species) was reported on August 22, 2025, in the Upper basin and channel between Tadd and Upper basins. Dead (mostly Bluegill and Yellow Perch) and distressed (Black Bullhead) fish were observed on the surface of both basins and the channel. Rooted submergent vegetation was sparse in both basins, but duckweed was covering the entire surface area of Tadd basin. Water clarity was less than 1 foot and brown in color in both basins. The aeration units (surface "ice eaters") were not operating due to mechanical issues and dense floating duckweed. The weather was hot and muggy during several days prior with a storm cell going thru followed by mild weather just before the summerkill. We deployed one continuously recording D.O.-Temp meter in each basin on August 25 and August 27, 2025 before noon. Dissolved oxygen fluctuated between 0-7 ppm with readings < 1 ppm for significant periods at night. The state fish pathology laboratory could find no disease responsible for the fish kill. The cause of the summerkill was most likely due to low dissolved oxygen. A targeted survey is generally used for sampling a specific kind of fish or time of year (i.e., spawning season, fall season, etc.) unlike a standard survey which samples a wider range of fish species during the summer months using standard methodology (i.e., standard time of year, set sampling stations, taking water clarity readings and oxygen/temperature profiles, etc.) and gears (i.e., lake survey gillnets, trapnets and possibly spring electrofishing for Largemouth Bass). Tadd & Upper is a small (39 acres), shallow (8 feet maximum), aerated (surface bubbler "Ice Eater" on both Tadd and Upper basins), productive and multi basin lake located in Kandiyohi County. Tadd & Upper was chemically reclaimed with rotenone in fall of 1989. Tadd & Upper was stocked with gamefish and panfish the following years and aeration systems were operated. A partial summerkill of Bluegill and Walleye occurred during the 1995 summer. Partial winterkills also have periodically occurred even with the operation of the aeration systems. Tadd & Upper may rarely connect to other upstream ditches and shallow lakes during high water events via tiles and storm sewer connections. Water levels were above normal during 2025. Submergent vegetation densities can vary from sparce to dense depending upon winterkill and fish species composition. Curly-leaf pondweed densities were high in Tadd & Upper basins during 2021. Aquatic vegetation species such as water moss and filamentous algae were abundant within Tadd & Upper during 2016. Previous targeted surveys were conducted with lake survey trapnets during mid-June of 2016 and May of 2021. Tadd & Upper is currently managed as a Kid's Fishing Pond in the Spicer Area. Fishing piers are located on both basins. Fish stocked during 2014 included Yellow Perch (1,400 fish, 300 pounds), Bluegill (700 fish, 100 pounds), Walleye (85 adult/yearling fish, 50 pounds) and Fathead Minnows (43 pounds). It was also stocked with small numbers of other gamefish (sauger, walleye, bass, and Northern Pike) and panfish (Bluegill, Black Crappie, Yellow Perch) from the Kandiyohi County Fair Display in 2014. Fish stockings in 2015 included adult Bluegill (700 fish, 100 pounds), Yellow Perch (480 fish, 120 pounds) and Walleye (31 fish, 24 pounds). In 2016, adult Bluegill (150 fish, 43 pounds) and Walleye (27 fish, 33 pounds) were stocked in Tadd & Upper. In 2018, Yellow Perch adults were stocked (360 fish, 90 pounds). Walleye yearlings (117 fish, 39 pounds) and adults (324 fish, 261 pounds) were stocked in 2019. Yellow Perch were recently stocked in 2021 (1,200 adults, 300 pounds) and 2023 (798 yearlings, 145 pounds). Northern Pike were stocked recently in 2022 (522 fingerlings, 2 pounds). Largemouth Bass were recently stocked in 2023 (49 fingerlings, 33 pounds) and 2024 (103 yearlings, 32 pounds). In addition, various display fish species from educational events and the county fair have been stocked into Tadd & Upper basins on occasion during recent years. A bottom bubbler was the primary aerator type for Tadd & Upper basins from the early 1990's through the 2017-18 winter. The Upper basin typically maintained higher winter dissolved oxygen levels than the Tadd basin. The bottom bubbler aeration system has struggled to maintain winter oxygen levels greater than 2 ppm especially in the Tadd basin during harsh winters. The aeration system was not run in 2012-13 winter due to the high numbers of Common Carp and Black Bullhead in Tadd & Upper. The 2012-13 winter was uncharacteristically cold, long and high in snowfall accumulation. A significant winterkill occurred during January/February of 2013. Numerous dead fish (Common Carp, Yellow Perch, Walleye, Northern Pike, Black Bullhead, Black Crappie, etc.) were observed in the water and on shore. The water was brown/gray stained with a temperature of 56 F during the netting. We did not capture any fish in the 1/2-inch mesh trapnets except for turtles (Painted and Snapping) during the 2013 spring. Walleye fry (249,544 fish) were stocked in May of 2013. Tadd & Upper was successfully used as a Walleye fingerling rearing pond in 2013. DNR Fisheries Personnel harvested 1,279 pounds (31,975 fish) of Walleye fingerlings from Tadd & Upper. The city of Atwater aerated Tadd & Upper to prevent winterkill of the remaining Walleye during the 2013-14 and 2014-15 winters. Low dissolved oxygen levels occurred in both the aerated and non-aerated basins during early January of 2017. Numerous Common Carp and Black Bullhead were observed in the open water aerator area in 2017. A joint decision by the city and DNR to cease aeration operations was made in January to facilitate a kill of undesirable fish in the basins. Unfortunately, abundant numbers of Black Bullhead survived the 2016-17 winter in Tadd & Upper basins. Reverse aeration was attempted during late February on both basins during the 2018-19 winter to facilitate the winterkill of less desirable fish species (Common Carp and Black Bullhead). The bubbler aeration systems were not turned on for 2018-19 winter. Oxygen levels were initially high during mid-December of 2018 (9.0-12.7 ppm), low during mid-January of 2019 (0.5-0.75 ppm) and early February of 2019 (0.5-2.4 ppm), and near zero (0.32 ppm) during mid-February of 2019. Aeromix aerators were started and pointed into the mud to mix non oxygenated water throughout the water column and facilitate winterkill on February 19, 2019 and continued until ice out in mid-March. Reverse aeration was only partly successful. Ice out trapnetting yielded abundant numbers of Fathead Minnows and small sized Black Bullhead, low numbers of small sized Yellow Perch and adult Black Bullhead. We observed dead Common Carp along the shorelines in the 2019 spring. The Tadd basin aeration system was changed to an Ice Eater surface bubbler in 2020-21 winter to the present. The bottom bubbler aerator was used on Upper basin during the 2020-21 winter. The Upper basin system was changed to an Ice Eater surface bubbler in 2021-2022 winter. Winter oxygen levels were adequate on Tadd (3.0-4.0 ppm) and excellent on Upper (11.0-13.0 ppm) basins during the 2020-21 winter. Aeromix surface aerators had also been used during past years on Upper basin with the bottom bubbler aerators were under repair. The Ice eater systems are currently run year-round to provide better oxygen and less stagnant conditions throughout the summer months. One disadvantage with this system is that small turtles or abundant submergent vegetation can damage the propellers or hinder the operation of the aerators during the summer months. Aeromix aerators may be a better option for the summer months and ice eaters for the winter months. The Aeromix aerators can sometimes open to much open water in the winter causing signposting and safety concerns. Black Bullhead numbers (121.50 fish/trapnet) were abundant in the 2025 spring trapnets. Black Bullhead numbers were low (11.75 fish/trapnet) in the fall netting. Black Bullhead average sizes were small in the spring (0.16 pounds and 6.18 inches) and fall (0.17 pounds and 6.88 inches) nettings. Black Bullhead numbers (21.00 fish/trapnet, 7.65 inches) were moderate in the 2021 trapnets. One large (32.20 inches) Channel Catfish was captured in the 2025 spring trapnetting. Black Crappie were absent in the 2025 spring trapnets but moderate numbers were present in the 2025 fall trapnets (4.00 fish/trapnet). YOY Black Crappie accounted for 81% Black Crappie catch. The adult Black Crappie average length was 8.45 inches. Northern Pike numbers were moderately abundant (3.00 fish/trapnet, 25.34 inches) in the 2025 spring trapnetting. Only one Northern Pike was captured in the 2025 fall trapnetting. Walleye numbers were low (0.5 fish/trapnet, 15.45 inches) in the 2025 spring trapnetting. No Walleye were captured in the 2025 fall trapnetting. Walleye were not captured in the 2021 trapnets. Walleye numbers were abundant in 2016 (44.17 fish/trapnet), but the average size was small (0.25 pounds and 9.20 inches). Walleye growth rates were stunted even though adequate numbers of small sized forage species such as Yellow Perch and sunfish were present during 2021 in Tadd & Upper. Yellow Perch numbers were abundant (31.25 fish/trapnet, 5.94 inches) in the 2025 spring trapnetting, but low (1.00 fish/trapnet, 6.32 inches) during the 2025 fall. Yellow Perch were low (3.75 fish/trapnet, 8.36 inches) in 2021. Yellow Perch were abundant in 2016 (32.67 fish/trapnet). Bluegill numbers were abundant in the 2025 spring (27.25 fish/trapnet, 5.75 inches) and fall (43.50 fish/trapnet, 5.96 inches) trapnetting. Bluegill numbers were moderately abundant both in 2021 (21.50 fish/trapnet) and 2016 (21.33 fish/trapnet). The 2021 Bluegill average size was small (0.11 pounds and 5.01 inches). Pumpkinseed and Green Sunfish numbers were low in the 2025 spring trapnetting (1.75/trapnet and 0.00/trapnet respectively), but abundant in the fall netting (24.00 fish/trapnet and 5.75 fish/trapnet respectively) Hybrid Sunfish numbers were high (17.00 fish/trapnet) in the 2025 fall trapnetting. Common Carp were not captured in Tadd & Upper survey trapnets during 2025, 2021 or 2016. Low numbers of both Black Bullhead (adults and YOY) and Common Carp (YOY) were captured in a 2014 special fall trapnet (1/4-inch mesh) assessment. These fish may have resulted from survivors of the previous winterkill event, but more likely due to movement into Tadd & Upper via tiles connecting to other water bodies during the high-water conditions of June-July of 2014. Numerous dead Common Carp were observed following a 2019 partial winterkill. Current fish management activities on Tadd & Upper include managing it as a Kid's Fishing Pond, periodic winter oxygen testing, proposing and budgeting for aeration equipment changes, protecting the important aquatic habitats such as emergent and submergent vegetation through the permit process, assisting aquatic plant management and enforcement personnel in educating boaters and monitoring access sites for potential invasive species introductions, encouraging land owners to implement best management practices in the watershed, and stocking various fish species as warranted. Ice out trapnet assessments will be conducted if winterkill is suspected. All fish species will be sampled in 2028 by spring electrofishing and April/May trapnetting. If Common Carp and Black Bullhead numbers overtake the lake in the future, an induced winterkill by not operating the aerators may be again necessary.

The Ice eater systems are currently run year-round to provide better oxygen and less stagnant conditions throughout the summer months. Black Bullhead numbers (21.00 fish/trapnet) were moderate in the 2021 trapnets. The Black Bullhead historical average catch rate is 80.38 fish/trapnet. The 2021 Black Bullhead average size was moderate (0.29 pounds and 7.65 inches). The historical average weight is 0.27 pounds. Walleye were not captured in the 2021 trapnets. Walleye numbers were abundant in 2016 (44.17 fish/trapnet, but the average size was small (0.25 pounds and 9.20 inches). Walleye growth rates were stunted even though adequate numbers of small sized forage species such as Yellow Perch and sunfish were present in Tadd & Upper. Yellow Perch numbers were low (3.75 fish/trapnet) in 2021. Yellow Perch were abundant in 2016 (32.67 fish/trapnet). The Yellow Perch historical average catch rate is 6.17 fish/trapnet. The 2021 Yellow Perch average size was large (0.33 pounds and 8.36 inches). The Yellow Perch historical average weight is 0.24 pounds. Bluegill numbers were moderately abundant both in 2021 (21.50 fish/trapnet) and 2016 (21.33 fish/trapnet). The 2021 Bluegill average size was small (0.11 pounds and 5.01 inches). The Bluegill historical average weight is 0.27 pounds. Bluegill growth rates were within the Spicer Area normal ranges for ages 1-6 and above the normal ranges for ages 7-8. The 2018 year class comprised 85% of the 2021 Bluegill catch. Pumpkinseed and Green Sunfish were also moderately abundant (21.00 fish/trapnet and 7.75 fish/trapnet respectively) in the 2021 trapnets. Hybrid Sunfish numbers were low (2.75 fish/trapnet) in 2021. Sunfish species captured during 2016 included low to moderate numbers of Green, Hybrid and Pumpkinseed Sunfish. Common Carp were not captured in Tadd & Upper survey trapnets during 2021 or 2016. Low numbers of both Black Bullhead (adults and YOY) and Common Carp (YOY) were captured in a 2014 special fall trapnet (1/4-inch mesh) assessment.

If Common Carp and Black Bullhead numbers overtake the lake in the future, an induced winterkill by not operating the aerators may be again necessary.

Tadd & Upper is a small (39 acres), shallow (8 feet maximum), aerated (bottom bubbler on Tadd, surface Aeromix type on Upper), productive and multi basin lake located in Kandiyohi County. Tadd & Upper is currently managed as a Kid's Fishing Pond in the Spicer Area. A fishing pier is located on the Tadd basin. Presently, various submergent vegetation species, water moss and filamentous algae are abundant within Tadd & Upper. A targeted survey was conducted with standard lake survey trapnets at historical stations during mid-June of 2016 to assess fish abundance in order to make stocking decisions and monitor over winter survival as a Kid's Fishing Pond. Tadd & Upper will be surveyed every five years with standard lake survey nets at the same historical time and stations to allow comparisons to previous surveys. Spring trap netting (1/4" mesh) may also occur if winterkill is suspected. The bottom bubbler aeration system has struggled to maintain winter oxygen levels greater than 2 ppm in the Tadd basin during harsh winters. The aeration system was not run in 2012-13 winter due to the high numbers of Common Carp and Black Bullhead in Tadd & Upper. The 2012-13 winter was uncharacteristically cold, long and high in snowfall accumulation. A significant winterkill occurred during January/February of 2013. Numerous dead fish (Common Carp, Yellow Perch, Walleye, Northern Pike, Black Bullhead, Black Crappie, etc.) were observed in the water and on shore. The water was brown-gray stained with a temperature of 56 F during the netting. We did not capture any fish in the 1/2 inch mesh trapnets except for turtles (Painted and Snapping) during the 2013 spring. Walleye fry (249,544 fish) were stocked in May of 2013. Tadd & Upper was successfully used as a Walleye fingerling rearing pond in 2013. DNR Fisheries Personnel harvested 1,279 pounds (31,975 fish) of Walleye fingerlings from Tadd & Upper. The city of Atwater aerated Tadd & Upper to prevent winterkill of the remaining Walleye during the 2013-14 and 2014-15 winters. Walleye growth appeared stunted for the remaining Walleye present during this time period. Fish stocked during 2014 included Yellow Perch (1,400 fish, 300 pounds), Bluegill (700 fish, 100 pounds), Walleye (85 adult/yearling fish, 50 pounds) and Fathead Minnows (43 pounds). It was also stocked with small numbers of other gamefish (sauger, walleye, bass, and Northern Pike) and panfish (Bluegill, Black Crappie, Yellow Perch) from the Kandiyohi County Fair Display in 2014. Fish stockings in 2015 included adult Bluegill (700 fish, 100 pounds), Yellow Perch (480 fish, 120 pounds) and Walleye (31 fish, 24 pounds). In 2016, adult Bluegill (150 fish, 43 pounds) and Walleye (27 fish, 33 pounds) were stocked in Tadd & Upper. Low dissolved oxygen levels occurred in both the aerated and non-aerated basins during early January of 2017. Numerous Common Carp and Black Bullhead were observed in the aerator open water area in 2017. A joint decision by the city and DNR to cease aeration operations was made in January to facilitate a kill of undesirable fish in the basins. A fish kill did not occur even though oxygen levels were low (<1.0 ppm) during a portion of 2016-17 winter. It appears that adequate fish survival occurred for all species except possibly sunfish during the 2016-17 winter based on ice out test netting in 2017. Presently a different type of aeration system (surface bubblers) is being considered for these basins. The 2016 targeted survey fish catch rates below are generally still valid for Tadd & Upper following the 2016-2017 winter. Black Bullhead numbers (50.83 fish/trapnet) were moderately abundant in the 2016 trapnets The 2016 Black Bullhead average size was small (0.20 pounds and 6.7 inches). The historical average weight is 0.26 pounds. Abundant numbers of Black Bullhead were also captured in ice out trapnets in 2017. Walleye numbers were abundant in 2016 (44.17 fish/trapnet, but the average size was small (0.25 pounds and 9.2 inches). Walleye growth rates were stunted. The 2013 Walleye year class comprised 99% of the 2016 Walleye trapnet catch. Moderate Walleye numbers and similar size were captured in ice out trapnets in 2017. Yellow Perch numbers were abundant in 2016 (32.67 fish/trapnet). The 2016 Yellow Perch average size was small to moderate (0.10 pounds and 5.9 inches). Yellow Perch growth rates were excellent. The 2015 Yellow Perch year class comprised 93% of the 2016 Yellow Perch catch. Abundant number of Yellow Perch were captured in ice out trapnets in 2017. Bluegill numbers were moderately abundant in 2016 (21.33 fish/trapnet). The 2016 Bluegill average size was moderate (0.17 pounds and 6.1 inches). Bluegill growth rates were excellent. The 2014 and 2013 comprised 39% and 29% respectively of the 2016 Bluegill catch. Other sunfish species captured during 2016 included low to moderate numbers of Green, Hybrid and Pumpkinseed Sunfish. Low numbers of sunfish were captured in ice out trapnets in 2017. Common Carp were not captured in Tadd & Upper survey trapnets during 2016. Unfortunately, small numbers of both Black Bullhead (adults and YOY) and Common Carp (YOY) were captured in a 2014 special fall trapnet (1/4 inch mesh) assessment. These fish may have resulted from survivors of the previous winterkill event, but more likely due to movement into Tadd & Upper via tiles connecting to other water bodies during the high water conditions of June-July of 2014. Current fish management activities on Tadd & Upper include managing it as a Kid's Fishing Pond, periodic winter oxygen testing, proposing and budgeting for aeration equipment changes, protecting the important aquatic habitats such as emergent and submergent vegetation through the permit process, assisting aquatic plant management and enforcement personnel in educating boaters and monitoring access sites for potential invasive species introductions, encouraging land owners to implement best management practices in the watershed, and stocking various fish species as warranted. Ice out trapnet assessments will be conducted if winterkill is suspected. All fish species will be sampled in 2021. If Common Carp and Black Bullhead numbers overtake the lake in the future, then an induced winterkill by not operating the aerators may be again necessary.
