STREAM GAGES

West & East Branch Delaware River

The West Branch Delaware River and its tributaries are the source waters for the Cannonsville Reservoir, part of the Catskill/Delaware drinking water supply system for the New York City water supply system operated by NYC Department of Environmental Protection (DEP). The watershed above the Cannonsville Reservoir encompasses an area of 353 square miles with approximately 662 total stream miles. The East Branch of the Delaware River is located principally in Delaware County on the eastern portion of the Allegheny Plateau physiographic province. The upper portions of the East Branch, with its eight tributaries, contribute water to the Pepacton Reservoir. The total drainage area of the East Branch Delaware River watershed above the reservoir is 371 square miles with approximately 644.4 total stream miles.

Delaware County Soil & Water Conservation District

Delaware County Soil and Water Conservation District’s (DCSWCD) Stream Management Program (Stream Program) is a partnership formed between the DCSWCD and the NYC Department of Environmental Protection (DEP).  Delaware County hosts two NYC drinking water supply systems which are part of the largest unfiltered water supply in the United States. In order to protect this irreplaceable natural resource, the United States Environmental Protection Agency requires NYC DEP to develop comprehensive and innovative watershed protection programs as part of their requirement of the 1997 Memorandum of Agreement (MOA) and Filtration Avoidance Determination (FAD).

Stream Management


Stream Management Plan Implementation Funding

The Delaware Watershed Stream Management Grant Program offers assistance to local communities, residents, and organizations to advance recommendations from the East and West Branch Delaware River Stream Corridor Management Plans. Categories of funding include: Flood Management, Highway and Infrastructure Improvement, Stormwater Implementation and/or Critical Area Seedling, Recreation-Based Opportunities or Habitat Enhancements, General Restoration Projects, Education/Outreach/Training, on Watershed Protection, and Planning & Assessment.

Project Maps

West Branch Project Map

East Branch Project Map

Stream projects are one component of the NYCDEP SMP). The primary goals of stream management projects include water quality improvement through the reduction of bed or bank erosion and the associated turbidity and other pollutants, infrastructure and/or property protection (flood hazard mitigation), aquatic habitat enhancement and riparian restoration and/or protection. These locally based demonstration projects support the education and training component of the SMP. Natural channel design principles are incorporated wherever possible into projects to ensure multiple benefits are achieved.

Project Maps provide information on a selection of full channel stream restoration, stormwater and infrastructure, riparian buffer restoration, streambank stabilization, and floodplain restoration projects that have been constructed to meet multiple objectives including: infrastructure protection, improved flood conveyance and sediment transport, improved fish habitat, and improved riparian functions.

United States Geological Survey (USGS) Stream Gages

The United States Geological Survey (USGS) maintains 11 continuous-recording stream gages in the West Branch Delaware River watershed above the Reservoir and seven continuous-recording stream gages in the East Branch. These gages measure the stage, or height, of the water surface at a specific location, updating the measurement every 15 minutes. Click on the Station ID number of your gage of interest to receive real-time water surface data from USGS.
