Description

EPA and its state, tribal, federal and other partners have completed the report highlighting the work on the first survey of the nation's rivers and streams (National Rivers and Streams Assessment, NRSA 2008-2009). This survey combines an assessment of the nation's rivers with the second national survey of small wadeable streams (Wadeable Streams Assessment (WSA)). Planning is also underway for the next survey of the nation's rivers and streams (NRSA 2013-2014).

This survey uses a random sampling design to provide regional and national estimates of the condition of rivers and streams. States and tribes use consistent sampling and analytical procedures to ensure that results can be compared across the country and over time. The NRSA is one of a series of surveys being implemented to periodically generate statistically-valid and environmentally relevant reports on the condition of the nation's water resources. These collaborative assessments are also intended to improve monitoring across jurisdictional boundaries and to enhance the ability of states and tribes to assess and manage water quality.
