I've been trapping BG from my very small spring fed pond into my larger almost 2ac pond.

I have a chunky 3lb bass that has been hanging out under my dock and likes to grab a BG as I drop them into the pond. The first time he did it I thought it was a little bass so i dangled a jig and caught a nice fat bass. He came back a couple days later and since then has been a consistent feeder.
