Here we only have 1 lake with water snakes in it. That is the same lake that has large mouth bass in it as well. The large mouths were put illegally and the snakes have all but disappeared. I am not sure if the snake population dropped from the bass or eagles and ospreys. But I know thatthe snake populationhad dropped alot reguardless. To buy something like this for use on just one lake up here I would pass it up.
