Posten Kill and Quacken Kill

The Poesten Kill is stocked annually with over 6,000 brown trout by the
DEC with some contribution to the fishery by a wild brown trout population.
There is a small wild brook trout population in the headwaters area of the
Poesten Kill. The Quaken Kill is not stocked; however, it does have a wild
brown trout population to provide a challenge to anglers.
