This is a nice little "pond" to fish, have fished it for years. Some nice bass to be caught, pearch and bluegill from shore. I have caught one trout here, but mostly go for bass
Not so much a pond as an area of the Blackstone that has been enlarged due to the Fisherville mill dam.
I am not sure of the exact depth but I do know that many people use small hp engines here so it is deep enough for most smaller boats. Use caution though as it is a river and of course levels vary with season/rainfall/etc.
A public boat ramp, dirt but large enough for trailers, can be found behind the Riverview Apartments off 122 in Grafton. Just turn into the apartments, follow to the left and past the dumpsters, not hard to find.
