Napa River Sediment TMDL and Habitat Enhancement Plan

Background

The Napa River and its tributaries are listed as impaired because of too much sediment. The listing was made in response to concerns regarding adverse impacts to habitat for steelhead trout, chinook salmon, and other threatened species whose populations have declined substantially in recent decades. The Napa River Sediment TMDL and Habitat Enhancement Plan examines this water quality problem, identifies pollutant sources, and specifies actions that will restore a healthy fishery in this watershed.

TMDL Implementation


Conditional Waiver Program for Vineyard Facilities in the Napa River and Sonoma Creek Watersheds

Water Board staff is developing a Conditional Waiver of Waste Discharge Requirements for Vineyard Facilities in the Napa River and Sonoma Creek Watersheds (Vineyard Waiver), in which many vineyard owners and/or operators would be required to enroll. Staff will solicit input from stakeholders during this waiver development process. The essential component of the Vineyard Waiver will be the vineyard owner/operatorís completion of a farm water quality plan (farm plan). A farm plan includes a comprehensive inventory and assessment of natural resources, agricultural lands, and management practices. The farm plan must address surface erosion, storm water runoff, sediment delivery from roads, pesticide use, nutrient management, and protection of stream areas.
