We had a big rain several months ago, so big that the creek the runs on the back side of my property ran over into the pond. Ever since then we have seen some large carp. At first I thought they were eating duckweed that is forming around the pond. I think they are doing something else. They will go up to the edge of the pond and eat something I am not sure what. Are there eggs there or something? We have a lot of catfish in the pond and some blue gill and thats about it. The pond is 1 1/2 acres or so.
