Is this the Sterling Lake in Lake County? It's been a while since I have fished there but supposedly they have a good bass, catfish, panfish and walleye populations in there. I think there is even musky in that lake. The bridge area was always a pretty popular spot.
This lake has produced three 48"+ musky that I know of in the past two years. Which means this year they are 50". All the fish I heard caught were also released. The bass population is doing alright with decent numbers of small fish(9-13"). The walleye were restocked two years ago 3-5" fingerlings, but with the large pike and musky population and recent declines in walleye population and quality of size. Walleye are few and far between.
