Artificial lakes
The Tomhannock Creek watershed is made up of the lands draining into the Tomhannock Creek and its tributaries, Otter, Sunkauissia, and Indian Creeks. Tomhannock Creek enters the Hoosic River in the Town of Schaghticoke, and the watershed extends upstream to the northwest escarpment of the Rensselaer Plateau, around Babcock Lake and just north of Grafton Lakes State Park. This watershed contains the most important surface water source in Rensselaer County, the Tomhannock Reservoir in Pittstown.
