Leonard M. Wright, Neversink (1991) Atlantic Monthly Press. Wright had the good fortune to own not one but two properties on the upper Neversink and he spent considerable time and energy in trying to improve the habitat much like Hewitt before him. A good read and full of information on what it takes, as well as mother natures response, to improving a stream.
