Emergency Stream Intervention
What is ESI?
Emergency Stream Intervention (ESI) is a training program meant to be used to assess post-flooding conditions, decide where to and where not to work, and determine the correct approach needed to address problems under an emergency response condition. This program includes a training manual, resources needed for assessing stream and stream watersheds, and a series of training modules available as a pdf below, or as an online training session, currently under development.
Where did ESI Come From?
This program was initially developed through funding from the New York State Department of Environmental Conservation’s Water Quality Improvement Program, and in part through the Delaware County Soil and Water Conservation District Stream Management Program contract with the New York City Department of Environmental Protection’s Bureau of Water Supply. Subsequent edits were made to this manual by DEC to facilitate its use state-wide.

Static Drainage Area Maps for the Upper Susquehanna Coalition Watershed
The following maps of each topo quad in the New York portion of the watershed were developed by NYS DEC for use in determining drainage area from any stream point. The quads are sorted by county as follows.
