Fish Status |
Very Good | A total of 187 Black Crappie were collected ranging in size from 6.4 – 13.5", with 187 greater than stock size (3.1"). Average length was 8.4". Body condition met the 90th percentile target goal. A good body condition could indicate sufficient forage for fish growth. Despite Black Crappie densities being high, and good body condition, very few above quality-sized Black Crappie were collected. | |
Improving | A total of 366 Bluegills were collected ranging in size from 0.8 – 7.5", with 294 greater than stock size (3.1"). Average length was 4.4". Body condition exceeded the 90th percentile. A high body condition indicates sufficient forage for fish growth. Despite Bluegill densities being high, and good Bluegill body condition, very few larger Bluegill were collected . This could be due to the high fishing pressure put on the lake. It’s also possible larger fish are present but were difficult to collect due to the large amount of vegetation in the water during the survey. | |
Excellent | A total of 119 Largemouth Bass were collected ranging in size from 3.1 – 19.6", with 92 of those fish greater than stock size (7.9"). Average length was 10.5". Body condition exceeded the 90th percentile. A high body condition indicates sufficient forage for fish growth. Overall, the Largemouth Bass population looks to be in good shape. | |
Excellent | A total of 43 Muskellunge were collected ranging in size from 16.1 – 41.5", with 42 of those fish greater than stock size (20.1"). The average length was 32.6". Body condition exceeded the 90th percentile. A high body condition indicates sufficient forage for fish growth. | |
Good | A total of 6 Walleye were collected ranging in size from 14.4 – 28.3", with 6 of those fish greater than stock size (9.8"). Only 6 fish were collected during the survey due to warmer-than-usual water temperatures. Another survey will be conducted in 2026 to evaluate Walleye stocking success in the lake. | |
Good | A total of 36 White Crappie were collected ranging in size from 7.8 – 14.0", with 36 greater than stock size (3.1"). Average length was 10.0". Body condition fell just below the 90th percentile. A low body condition might indicate insufficient forage for fish growth. Despite White Crappie densities being low, size quality is high. | |
