Grape Creek, a tributary to Dry Creek and the Russian River, flows
from the western side of the Dry Creek Valley west of the city of
Healdsburg. The Grape Creek system drains a basin of
approximately 3.2 square miles and includes 2.9 miles of USGS blue-line streams.
Elevations in the watershed range from 900 ft. at the
headwaters to approximately 80 ft. at the Dry Creek confluence.
Flow in this system varies seasonally, ranging from a continuous
perennial flow to ephemeral, disconnected pools.
Currently all the land in this watershed is in private ownership with a
significant portion in vineyard cultivation. Natural vegetation types
occur mostly in the upper portion of the watershed as mixed conifer, hardwood
and chaparral forest.
CDFG and National Marine Fisheries Service (NMFS) surveyed
Grape Creek in 1998 and 2007 respectively, and found adult and
juvenile steelhead as well as steelhead redds (gravel nests where they lay their eggs).
Historically, this stream supported coho salmon, but this
species has not been sighted in recent years and in 2010, the
Russian River Coho Salmon Captive Broodstock Program
reintroduced hatchery coho into this system. There are also several
partial barriers along this creek that limit salmonid passage and
access to stream habitat. Grape Creek is classified as a Phase I
expansion area for coho salmon recovery in the NMFS Coho Recovery Plan, 2010,
making it a priority watershed for near-term coho
Projects (completed or pending)
- Instream habitat enhancement including large woody debris and
rock structures to provide improved summer rearing habitat for
- Streambank stabilization and riparian revegetation.
- Vineyard and winery water conservation.
- Fish passage improvement at road crossings.
- Frost protection alternatives.
