I will likely be sorry, but since I have had little luck getting eelgrass to establish in either of my ponds, I think that I will leave the curly leaf pondweed. My other pond has very few submerged weeds, and if this gets out of control, I may add a single grass carp to the pond to cut it back (I think the pond is under 1 acre). Is there any way to reliably catch GC once they are released on rod and reel?
