Did it in a river off Lake George many years ago. I thought it was illegal now but I guess not. It was pretty easy to fill a gallon bucket which was the limit as I remember. We went to a spot in the river with a small wire basket taped to a pole and scooped them up as they ran the river. Prime spots were around boulders and bends in the brook.
I wish we could do it again but I think it would lead to fight over spots more likely
