The Beaverkill River is approximately 44 miles long and is a tributary of the East Branch of the Delaware River.  The Beaverkill River travels through the Catskill Mountains and is famous for its outstanding Trout fishing.  The lower Beaverkill begins at "Junction Pool" in Roscoe, where the waters of the Upper Beaverkill merge with the Willowemoc. The river then flows westward for 15 miles, where it joins the East Branch of the Delaware at the village of East Branch.
