The Rivers And Their Ecology![]() East Branch Delaware River – The East Branch is dammed by the Pepacton Reservoir, a huge impoundment over 15 miles in length. Because the watershed upstream of the reservoir is largely forested, the near-pristine water quality is highly valued by New York City. As a result, over half of the East Branch's water is diverted for drinking water, and the river has suffered from chronic low flows. The East Branch holds wild trout throughout the 33 miles it flows from the dam to its confluence with the West Branch. It is a prime spawning ground for American Shad and home to the one of last commercial eel weirs across the vast Delaware River watershed.
