You might check with McBride Biologist, Paul Sleeper. Paul directed a telemetry study of the walleye on Lake McBride in the mid-90s. It makes for interesting reading. The readers digest version is this…stay shallow, 6ft or less. With all the work done on this lake in the last two years the fishing should improve. As for why this lake is the only state-managed lake in Iowa with horse power restrictions-ask state rep. Bob Dvorsky where all his campaign money comes from. He is the problem. Good luck and good fishing.,
