I live in Whitestown, about 30 minutes north of Indianapolis.

Might wait on the grass carp then and see if I have a problem. Was just told to get a head start on the grass as most ponds in our area do have a problem due to run off from farm land; i.e. high phosphate.

I have alot of small and large size structures in the breeding area.
