Status of the Fishery (as of 07/13/2009)

Cedar Lake is a 169 acre class 24 lake located in the Minneapolis Chain of Lakes. These lakes are heavily impacted by the surrounding city. Storm water runoff impairs water quality. Numerous water quality improvement projects have been implemented, minimizing impacts from the surrounding city. Motor restrictions on the Minneapolis Chain of Lakes prevent Cedar Lake from experiencing heavy surface use. There is carry-in access near the fishing pier. Shore fishing is very popular on Cedar Lake.

The predator community in Cedar Lake is diverse. Four species are present. Cedar Lake walleye abundance increased to the highest value ever recorded. Stocking fingerlings is responsible for this increase. Walleye stocking began in 2005. Stockings occurred in 2007 and 2009, and will continue in odd numbered years. Walleye mean length was 16.26 inches. Mean weight was 1.94 pounds. Both abundance and average weight were above average. Northern pike numbers were low. This is typical of Cedar Lake. In the 2009 population assessment largemouth bass abundance was high. Largemouth bass averaged 9.53 inches and 0.58 pounds. Keep in mind standard lake survey gear does not consistently provide an accurate estimate of LMB abundance. Hybrid muskellunge, also called tiger muskie, are present in Cedar Lake. Stocking of hybrid muskellunge occurs once every three years.

Five species of panfish are present in Cedar Lake. Black crappie abundance is below average. Very few large fish were sampled. Bluegill abundance decreased compared to the 2005 survey, but stayed within Cedar Lake's average range. Abundance remains above average and average weight increased slightly. Only 11.4% of sampled bluegill were greater than 6 inches. The bluegill poulation in Cedar Lake is stunted. Yellow perch abundance in Cedar Lake is below average. Mean weight of yellow perch was average. Pumpkinseed were sampled at an average abundance. Hybrid sunfish were also sampled.

Rough fish are present in very low numbers. Common carp abundance increased slightly since the 2005 survey, but remains low. Black bullhead were also sampled at low abundance. This is typical for Cedar Lake. Yellow bullhead were not sampled. Previous surveys found yellow bullhead to be low as well.

In the Metro area, stunting in size is likely due to overpopulation and size selective harvest by anglers. Overpopulation reduces the amount of food available to all fish, thus reducing growth rates. Harvest of larger (keeper size) fish by anglers reduces the number of quality fish in a lake. Harvesting large fish also removes the spawning stock and reduces the biological incentive to grow large. Larger fish compete for spawning habitat and food more effectively. Thus, fish have more incentive to grow large if large fish remain in a lake. Harvesting smaller fish preserves spawning stock and increases the biological incentive to grow large which promotes big fish genetics.
