West Branch Delaware Rivers

Introduction

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 New York City. The watershed above the Cannonsville Reservoir encompasses an area of 353 square miles with approximately 662 linear miles of rivers and streams. This predominantly forested and agricultural watershed represents a sizeable and challenging resource to comprehensively manage. Stream walkover observations and assessments suggest that the West Branch Delaware River has a tendency to become shallower and wider that is desirable due to increased sediment supply from excessive bank and bed erosion in the main river and its tributaries. While erosion and deposition are natural processes, many management activities can significantly increase erosion rates that in turn contribute to increases in sediment supply. These conditions demonstrate the need for comprehensive management and stewardship by all stakeholders.

Delaware Watershed Stream Management Grant Program (Click Here)

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.

USGS Gage Links

The United States Geological Survey (USGS) maintains 11 continuous-recording stream gages in the West Branch Delaware River watershed above the Reservoir. 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.
