I have a small sediment pond its about 30' by 30' and was about 14' deep when originally dug. I have tried many different forage fish in it but the only thing that seems to live in it is the FHM. That is because of turbid water events after a good rain. And that is why I built it. What I have learned is this pond when raising FHM's it will attract Bull Frogs of different sizes. Apparently, Bull Frogs like FHM. Last time I had fhm's in this pond I counted 14 in all sizes in this small sediment pond. They don't dare get in the big pond lol. Funny how that is.
