Not sure, but I have seen some guys take their own little boat and fish
When I was there they only rented out duck shaped paddle boats not for fishing. I also saw a park ranger giving a citation to two guys that were apparently fishing. I don't know what offense they did. They had a movie being shot while I was there.
You can rent a paddle boat, but fishing on a boat is not allowed. However, you can fish by the lake, but i don't think you would want to eat the fish from there. They use chemicals to treat the water and it is not very clean. Just saying.
