Napa River Sediment TMDL Implementation Tracking and Accounting System

Napa County, with support from several partners, is developing a Napa River Sediment Total Maximum Daily Load (TMDL) Implementation Tracking and Accounting System (ITAS). The system will be designed to account for required and recommended implementation actions prescribed in the Napa River Sediment Reduction and Habitat Enhancement Plan (Napa River Sediment TMDL). Learn more.

Napa River Oakville to Oak Knoll Reach Restoration Project

The Napa River Restoration: Oakville to Oak Knoll Project is being developed to restore 9 miles of the Napa River from Oakville Cross Road to Oak Knoll Avenue. This reach is comprised of approximately 70 parcels and 34 different private entities. Historic changes in land use and management in the Napa River watershed have resulted in channel incision with bank failure, erosion of channel bedforms (riffles, bars, pools) important to salmonids, and a limited riparian corridor due to the lack of a functional floodplain.

Napa Valley Historical Atlas

The Napa Valley Historical Ecology Atlas will be a highly visual exploration of the native Napa landscape and its physical transformation over the past two centuries. Using rarely seen historical maps, photographs, and paintings, the Atlas will investigate this remarkable landscape and its contemporary remnants, establishing a new perspective on the iconic region we know today.

Suisun Creek Watershed Program

The Suisun Creek watershed encompasses 53 square miles in Napa and Solano counties. Three major creeks—White Creek, Wooden Valley Creek, and Suisun Creek—drain a watershed of steep, mountainous terrain and several large valleys into the Suisun Marsh and Suisun Bay. Steelhead trout (Oncorhynchus mykiss), a federally listed threatened species, have been found in the three main creeks of the watershed. This watershed has been named one of the primary “anchor” watershed streams with essential habitat for steelhead trout in the Bay area (CEMAR 2007). Learn more.

Watershed Assessment Framework

The Watershed Assessment Framework (WAF), as applied to the Napa River watershed, is a method of reporting on key indicators of watershed health over time to guide watershed management actions. Watershed health is defined broadly, to include ecological, terrestrial, aquatic, water-related, social, and economic measures. The outcomes of this application are an easily understood watershed health Report Card on the health of the Napa River watershed, and more in-depth technical report detailing the process and analysis behind the WAF application and development of the Report Card.

Rutherford Reach Restoration Project

The Napa River Rutherford Reach Restoration Project is comprised of a 4.5-mile reach of the mainstem Napa River south of the City of Saint Helena between Zinfandel Lane and the Oakville Cross Road. This reach is comprised of approximately 40 parcels owned and managed by 29 different private entities. Historic changes in land use and management in the Napa River watershed have resulted in confinement of the river into a narrow channel, loss of riparian and wetland habitats, accelerated channel incision and bank erosion, and ongoing channel degradation. Properties along the Rutherford Reach have been subject to bank instability and failure leading to the loss of valuable vineyard land and costly repairs. Learn more.
