BLUEGILL

Improving

A total of 168 Bluegills were collected ranging from 30 – 187 mm (1.2 – 7.4 in), with 26 > Stock size (80 mm [3.1 in]). Unfortunately, this survey did not meet the minimum required number of fish > Stock size (n = 50) to quantify population demographics as set forth in the lake management plan (LMP). However, I believed 26 fish > Stock size sufficient to continue with the analysis. The PSD and RSD-7 fell below its target ranges. Body condition (as indexed by relative weight) exceeded the 90th percentile for Quality and Preferred sized fish. 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 (as indicated by low the RSD-7 value).

LARGEMOUTH BASS

Excellent

A total of 69 Largemouth bass were collected ranging from 70 – 535 mm (2.8 – 21.1 in), with 33 of those fish > Stock size (200 mm [7.9 in]). This survey met the minimum required number of fish > Stock size (n = 30) to accurately quantify population demographics as set forth in the Lake Management Plan (LMP). Both the PSD and RSD-15 fell within their respective target ranges. Body condition (as indexed by relative weight) exceeded the 90th percentile for Quality, Preferred, and Memorable sized fish. A high body condition indicates sufficient forage for fish growth. Overall, the Largemouth bass population looks to be in great shape.

MUSKELLUNGE

Excellent

A total of 45 Muskellunge were collected ranging from 700 – 1055 mm (27.6 – 41.5 in), with 45 of those fish > Stock size (510 mm [20.1 in]). The 45 Muskellunge collected were mostly dominated by males given that only 11 out of the 45 were female. Later than normal cold temperatures may have made sampling a little early this year with water temperatures only around 46 degrees during sampling. The CPUE exceeded the goal of 1 fish per net night as set forth in the Lake Management Plan (LMP).

WALLEYE

Very Good

A total of 27 Walleye were collected ranging from 366 – 718 mm (14.4 – 28.3 in), with 27 of those fish > Stock size (250 mm [9.8 in]). Unfortunately, this survey did not meet the minimum required number of fish > Stock size (n = 30) to quantify population demographics as set forth in the lake management plan (LMP). However, I believed 27 fish > Stock size sufficient to continue with the analysis. Both the PSD and RSD-15 fell below their respective target ranges. Body condition (as indexed by relative weight) exceeded the 90th percentile for Quality, Preferred, and Memorable sized fish. A high body condition indicates sufficient forage for fish growth.
