Big Bass Lake 174 Acres Mean Depth 5 feet Max Depth 13 feet FISHERIES MANAGEMENT……………..….. we make fishing better Big Bass Lake Management History In 1952 the lake was stocked with 2m walleye fry and was to be used as a rearing pond. No results were found. In 1955 a survey found numerous walleye present from the single stocking. However in 1957 the lake was treated to kill the fish population and restocked with NP in 1959. A in 1968 showed the most common fish were YP, PKS, bullheads, and white suckers, max size for YP was 6.3” and PKS ranged to 5.9” 4 largemouth bass were caught and ranged (11.5 to 14.9”) 1 NP was caught (25.5”) NP were stocked throughout the last 60 years, but they do not appear to reproduce well in Big Bass Lake.

Big Bass Habitat Fisheries recommends more woody material in water and near shore Do not recommend Fish Cribs – the deep water is limited and they might concentrate fish too much Restoring the native vegetation to the shoreline. And preserve the existing natural shoreline Wadley Lake 46 Acres Mean Depth 9 feet Max Depth 27 feet Wadley Lake Management History In 1960s there was an attempt to stock walleye and produce a naturally reproducing population. Walleye were stocked in 1960, 62, 64, and 66 at a rate of 9,000 fingerlings per year. Only 1 walleye was collected in the 1967 lake survey and it was recommended that the stockings be discontinued. Wadley Lake was considered a LMB/Panfish lake and has had no other fishery management activities other than stocking There were attempts to establish NP thru stocking in later years In 2009 we attempted to place a more restrictive bass regulation on the lake: but the proposal did not get forwarded to hearing. DNR has not completed a full net survey of this lake since 1976. But has worked on the lake using electrofishing FISHERIES MANAGEMENT……………..….. we make fishing better Wadley Lake Stocking History Wadley Lake Species List UWSP 2012 Wadley Lake Bluegill 25 Number 20 15 EF 2006 Fyke Net 2012 10 5 0 3 4 5 6 Length (inches) 2006 2012 PSD 65 13 RSD8 3 0 7 8 2009 2012 PSD 62 73 RSD14 25 40 Largemouth Bass (Length at Age) Spring Survey Statewide Average Onland Wadley Average Length (inches) 16 14 12 10 8 6 4 2 0 2 3 4 Age 5 6 Relative Weights for LMB for Wadley Lake averaged 80% The WRs should average around 100% This was one reason we were requesting a regulation change Wadley Lake LMB WRs 130 Relative Weight 120 110 100 90 80 70 60 9 10 11 12 13 14 15 Length (inches) 16 17 18 19 20 21 Wadley Lake Management Goals Primary Objective: Maintain Bluegill PSD 35-60% current = 13% Maintain LMB PSD from 40-60%. current = 73% Secondary Objective: Bluegill RSD to > 20% current = 0% LMB RSD to >20% * current = 40% Regulations LMB have a slot limit: 3 bag, 14 to 18 inch closed slot, 1 fish may be > 18 inches Proposed Panfish: 5 bag, >7 inches. Wadley Lake Fish Habitat 2014 a fish crib permit was issued to extend a project started a few years ago. Maintain woody debris in water Add to tree drops in water Maintain the native vegetation in the lake which Konkel described as high quality but of poor diversity. Bluegill Remove vegetation in a radial pattern. Maintain emergent vegetation Size structure of bluegill improved Natural mortality decreased Overall there was an increase in the quality of the bluegill fishery Male bluegill select this vegetation type Largemouth Bass Vegetation is important winter habitat for juvenile bass Juvenile bass exhibited best growth when coverage was 20% of littoral zone Proper open space was critical in getting bass at 60mm to switch to fish. This enhances the first years growth significantly. Vegetation Recommendations for Enhancement of Fisheries Re-establish beds of emergent vegetation Cut or treat in radials Allow more vegetation within the 1.5-5.0’ littoral zone. Leave dead timber in the water
