We have a small pond (about 1/2 acre). It hasn't been stocked since the early 80's. Almost no one fishes it. We can catch piles of bass in the spring. We average 7-10 pre hour. Here is the kicker, they will only hit original rapala's. Medium or small and only silver and black. No matter what else you throw, you won't catch one. Summer and fall you can't get them to bite anything. Fish run to the small side. We keep all we catch. In the last couple of years we are catching a few slightly larger fish. Any idea on how the make them bite later in the year?
