Napa River Watershed Profile

SFEI analyzed historical and current conditions of the Napa watershed in terms of hydrology, sediment, channel morphology and habitat to develop a geographic framework for solving agricultural management challenges related to the 303(d) listing of sediment (impaired water quality). A complete picture of past and present condition of the watershed provides a context for an analysis of future management possibilities.

SFEI partnered with the Napa County Resource Conservation District and the Napa County Farm Bureau to develop a watershed-based framework for addressing agricultural management challenges related to improving the health of the Napa River ecosystem. In particular, the project sought to identify possible adaptive management measures that could allow the State Water Board to declare the Napa River unimpaired under section 303(d) of the US Clean Water Act.
