Sterling Vineyards Farms
Bear Flats Estate Vineyard
Bear Flats Estate Vineyard covers 87 acres on the Ritchie Creek alluvial fan where the creek exits Bothe Napa State Park. During floods, alluvial fan channels fill with cobble and boulders. Typically, these are then removed and piled alongside the channel. This bedload material needs to deposit into the Napa River to produce spawning beds for Chinook salmon.
Diamond Mountain Ranch
This 120-acre ranch is located on slopes near the top of Diamond Mountain, west of Calistoga. The limited water in this area encourages dry-farmed grapes on smaller vines. Intensive management is used to assure soil conservation on the steep terraced vineyards.
These vineyards occupy the valley floor directly below the Sterling Vineyards winery. The site is being managed to eradicate invasive non-native plants such as Giant reed and tree-of-heaven from the Napa River corridor.
Located at the western boundary of Napa County, approximately half of this 100-acre site is planted to vineyard. The managers of this site are working toward dry-farming to reduce their water use.
Conn Creek runs adjacent to this 78-acre site. As part of their farm plan, they are working with the Fish Friendly Farming Program on an invasive plant removal and revegetation plan for the riparian corridor along Conn Creek.
