I have a 4 acre, spring fed lake between Akron and Cleveland Ohio. It has established LMB and BG, sunfish.(4 years). It is a reclaimed gravel pit with 18-20 foot max depth. Half of lake is very variable in depth from very shallow to 10 feet. No outflow or dam, but lots of drainage into the lake. Lots of humps, sand, gravel. The other half is separated by a peninsula. That half is a "big bowl" that averages about 15 feet. I want to add some walleyes, perch and crappie for variety. Some of the BG are enormous and very healthy. Do you think the added species could work out with the established bass population?
