The East Branch of the Perkiomen Creek is part of the Perkiomen Watershed. The East Branch of the Perkiomen Creek starts in Bedminster, PA and flows through the Pennridge school district (East Rockhill Township, Perkasie Borough, Sellersville Borough, and West Rockhill Township) in Upper Bucks County PA. Eventually the East Branch of the Perkiomen Creek flows into the Perkiomen Creek in Montgomery County, PA. The Perkiomen Creek then flows into the Schuylkill River, which flows towards Philadelphia, PA. The small creek behind our school - Pleasant Spring Creek - flows into the East Branch of the Perkiomen at the Dairy Queen near Lenape Park.

Tohickon Watershed

The Tohickon Creek begins in Haycock Township, PA. Its waters are dammed to create Lake Nockamixson State Park. The Tohickon Creek flows out of the manmade lake in Bedminster, PA and follows its original route; it eventually joins the Delaware River in Tinicum Township.

The Tohickon watershed is 73.3 square miles in size. The Tohickon Creek has historically been used as a source of power; between 12 and eighteen dams on the Tohickon furnished power to saw wood, grind grain, card wool, and lift water. Dams were used to make ponds where ice was cut during the winter and stored until needed in the summer months. The remains of two mills and four dams are located in Nockamixon State Park. One dam (in good condition) is located just behind the Weisel Youth Hostel on Richlandtown Road. The Tohickon Creek is the major tributary to the lake and has a drainage area of 44.5 square miles. Other major tributaries include Three Mile Run and Haycock Creek with drainage areas of 4.9 and 6.7 square miles respectively.
