The San Francisco Bay Delta is the largest estuary on the Pacific Northwest coast, draining over 40 percent of the water in California. This dynamic system supports more than 120 species of fish and other wildlife, is a critical waterfowl migration area and is important globally for commerce, navigation, fisheries and recreation.  The Napa River watershed provides the second largest supply of fresh water flow to the estuary.
          
         

Since 1987, the Napa River has been listed as an “impaired” water body. National Marine Fisheries Service has listed steelhead in the Napa River as threatened,  and Chinook salmon are listed as endangered (for a complete list of threatened and endangered species click here).

In 2004 the State Water Resource Control Board identified 1,777 illegal water diversions/dams on the north coast with 377 of these illegal water grabs in Napa County. Lack of adequate flows in north coast streams is causing aquatic mortality. Many of the streams in the Napa River watershed are dry or going dry year around due to over appropriation of riparian water and subterranean aquifers. This rapid and sustained need for riparian water began in the late 1960's and early 1970's as vineyards crawled into the mountainous regions of our watershed.

ICARE strives to balance human needs with sensible environmental protection, conservation, preservation and restoration. We work with the public to shape a balanced future for healthy watersheds and economic stability.
