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 Grape Creek watershed range from 900' at the headwaters to approximately 80' at the Dry Creek confluence.
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 NMFS surveyed Grape Creek in 1998 and 2007 respectively, and found adult and juvenile steelhead as well as steelhead redds. Historically, this stream supported coho salmon, but this species has not been sighted in recent years. National Marine Fisheries Services (NMFS) surveys have indicated that excessive levels of fine sediment and poor shelter quality are among the major limiting factors to salmonid habitat in Grape and Wine Creeks. There are also several partial barriers along this creek that limit salmonid passage and access to stream habitat.
Recent habitat enhancement efforts in this watershed include placement of several in-stream large woody debris and rock structures in order to provide improved summer rearing habitat for juvenile salmonids, as well as streambank stabilization and riparian revegetation. Flow in this system varies seasonally, ranging from a continuous perennial flow to ephemeral, disconnected pools. Three stream flow gauges are currently in place in the Grape/Wine Creek watershed as part of a cooperative program to monitor regional stream reach hydrology. Grape Creek is classified as a Phase I expansion area for coho salmon recovery in the Co-Manager Draft NMFS Recovery Plan, 2008 making it a priority watershed for near-term coho recovery efforts.
Grape / Wine Creek Gauge Data
Disclaimer: The gauge data reported here are preliminary, have not been verified, and may be unreliable for reasons including, but not limited to, instrument malfunction, undetected disruptions or interference occurring at the measurement site, or errors in interpretation. Please note that data are currently available only for water depth (not flow), temperature data has not been reviewed or calibrated, instruments may be located above the water levels in pools, and some instruments measure stage up to a certain height and will display a flat line at zero or the maximum height once that maximum measurable stage is reached.
