Delta WIN

About the Sacramento-San Joaquin Watershed
The Delta watershed extends nearly 500 miles from the Cascade Range in the north to the Tehachapi Mountains in the south, and is bounded by the Sierra Mountain Range to the east and the Coast Range to the west. The watershed includes the largest estuary on the west coast of North and South America and the only inland Delta in the world—the Sacramento-San Joaquin Delta (Delta). Nearly half of the surface water in California starts as rain or snow and flows downstream through the Delta and out to the Pacific Ocean through the Golden Gate Strait. The Delta Watershed Initiative Network (WIN) focuses on the subwatersheds within the legal Delta.

About the Delta Watershed Initiative Network (Delta WIN)
Good water quality is vital to key beneficial uses of water such as for drinking water, fish and wildlife, agriculture and recreational activities. Delta waterways are impaired by multiple pollutants including salinity, pathogens, pesticides, metals, mercury, nutrients, and invasive species. A myriad of agencies and organizations monitor and work to improve water quality in the Delta. Delta WIN takes a watershed approach and works to coordinate and facilitate a regional network of locally initiated projects to leverage resources to realize the ecological benefits of healthy watersheds.

Delta WIN’s main areas of focus include, coordinating water quality monitoring and implementing of best management practices (BMPs), data integration, environmental education, and wildlife stewardship.
