The Middle Russian Watershed consists of a number of smaller unnamed subbasins between Healdsburg and Riverfront Park just north of Forestville. The largest subbasin in this reach is the Brooks Creek watershed just south of the Maacama Creek Watershed. Brooks Creek is a fourth order stream and has approximately 3.77 miles of solid blue line stream. Brooks Creek drains a watershed of approximately 8.11 square miles. Elevations range from about 125 feet at the mouth of the creek to 1,529 feet in the headwater areas.
Turtle creek is a smaller stream system, unnamed on the USGS quadrangle map, which is also known as Griffin Creek or Bishop’s Ranch Creek, located near Sweetwater Springs Rd and Westside Rd. Turtle Creek is a first order intermittent stream and has approximately 3.5 miles of blue line stream. The creek drains a watershed of approximately 3.7 square miles. Elevations range from about 60 feet at the mouth of the creek to 600 feet in the headwater areas. The headwaters are located in a steep, narrow canyon that widens into a narrow valley and the creek drains from 3 lakes of approximately 1 acre in size. The first ½ mile of the stream was channelized during past gravel mining operations along the mainstem.
A minor unnamed tributary (commonly referred to as Keepo Creek) provides cooler temperatures through subsurface spring fed flow in the lower watershed. No suitable spawning or rearing habitat exists currently in Keepo Creek. However, a steelhead trout was observed in Turtle Creek by a red during the CA Dept of Fish and Game’s 1995 survey.
The lower watershed is managed for various small enterprises, including a nursery, equestrian stables and some vineyard development. The upper watershed is managed for open forest land as well as some cattle grazing. The upper watershed, from the largest reservoir upstream to the headwaters, is primarily owned by an academy of sciences. The rest of the watershed is almost entirely privately owned. Turtle Creek is also entirely privately owned. The watershed is dominated by vineyard, dairy, and pastureland, with gravel mining near the mouth of the watershed.
The mid and lower portions of the Brooks creek watershed have mixed conifer/hardwood zones as well as agricultural zones. The lower riparian zone is dominated by willow and bay laurel. Oak woodland forest dominates the watershed overall, as well as the upper riparian zones, but there are zones of grassland through. In turtle creek Vegetation in the upper watershed includes redwood, maple, alder, bay and oak, with willows, ash and cottonwood in the lower drainage area.
Fish and Wildlife
An assessment of Brooks Creek completed by the Department of Fish and Game in 2001 indicated salmonids present in several pools throughout the length of Brooks Creek that was surveyed. However, the biological inventory results in the report do not tally any salmonids identified. In the past, adult steelhead (Oncorhynchus mykiss) were commonly seen throughout Turtle Creek, and coho salmon (Oncorhynchus kisutch) occasionally, according to landowners.
Current and Past RCD Programs
- The RCD has worked with many Ag producers in Alexander Valley to enhance their farming operations and protect soil and water resources. Projects include the development of Farm Conservation Plans, enhancement of riparian areas, and erosion control.
Water Resource Management
- The RCD is working in Partnership with Syar Industries, the Westside Association to Save Agriculture, Advanced Viticulture LLC, and local grape growers to conduct an irrigation management field study. This study will focus on soil moisture and vine water status measurements in a variety of soil types common to the Middle Reach. Data will be key in helping local growers refine their irrigation scheduling to improve vine health and conserve water.
- In partnership with riparian landowners along the Middle Russian River and its tributaries, the RCD has undertaken a number of projects to enhance riparian habitat and stabilize eroding stream banks.
