New Technique for Subwatershed Investigations

The Center for Watershed Protection (CWP) has developed a new method to enable watershed practitioners to better assess upland watershed areas that can influence water quality.

The method, known as Unified Subwatershed and Site Reconnaissance (USSR), can be used to help develop watershed plans and can also help to identify specific audiences for education and outreach efforts. The CWP developed the USSR as a field survey that can be used by watershed groups, municipal staff, and consultants to quickly assemble a comprehensive initial inventory of potential pollution sources and restoration opportunities within urban subwatersheds. The USSR has four major assessment components: Neighborhood Source Assessment (NSA), Hotspot Site Investigation (HSI),  Pervious Area Assessment (PAA), and Streets and Storm Drains (SSD). CWP hopes the USSR can provide a quick but thorough characterization of all upland areas for the purposes of identifying major source areas that are contributing pollutants to the stream and controlling pollution sources through education, source controls, pervious area management, and improved municipal maintenance. http://www.cwp.org/PublicationStore/USRM.htm#usrm11
