Was out on a different Waukesha Co lake yesterday and water temp was 56 deg middle of lake and low to mid 60s in shallower area, to give you an idea Steve
Lac LaBelle, Waukesha County

The carp also eat and uproot vegetation off the bottom, and LLB is sparse in vegetation to begin with. The measured and recorded decrease in water clarity from 7' to 4' in less than 10 years is shocking. Weed lines generally stop when the water is deeper than where light can penetrate adequately. Rarely do I find a 10" weedline any more on LLB, they usually stop at 8'. Less places for predator and prey.
It's not known but suspected that propwash from pleasure boats increase turbidity and decrease water clarity in shallow lakes like LLB, but that's another story.
Carp do eat the algae and "gunk," but the amount of sediment they stir up while eating is crazy. And carp can totally overpopulate easily. I remember seeing a shallow reservoir in Kansas dry up. There were literally thousands of 8 inch carp lining the shores. It was one of the muddiest lakes I've ever seen.
Nice fish worm! Looks to be a female full of eggs, a good sign. I don't think I caught a 20" all last year. I don't think I caught the normal number of Small-eyes either. Study shows water clarity is down dramatically in less than 10 years, carp population seems strong as ever. Until they get the carp problem under control, I don't see a strong enough walleye population to even allow a 3 fish slot. If they keep up the walleye stocking, it'll probably be enough to keep it the catch and release Smalleye fishery that I have experienced since I started fishing LLB regularly in 2013.

Fished last night for a few hours. Kind of slow but I did manage this thick girl on a tip up. In the old days it would have been a keeper. Does anyone know what the long-term goal is as far as the walleye management is in this lake? For years they had the 20" limit which I understood was protecting the spawner females. Now the 28" limit pretty much eliminates all harvest. Is that the plan, to create a total catch and release fishery?

First time on this lake, I read there were a good number of small walleye. I hole hopped from the public launch out to the first island over a few hours and didn’t even mark a fish on the flasher. Fished along the break from anywhere in 4’-24’.
Found up to 12” of ice though. Do people drive trucks on this lake?
