2018 Stream Maintenance Program
2018 Stream Maintenance Program Improving water quality in our streams while providing flood protection for our community This summer the Sonoma County Water Agency (Water Agency) will be working in streams and channels throughout Sonoma County to improve water quality and provide flood protection. As part of our comprehensive Stream Maintenance Program (SMP), we will be removing sediment and garbage and planting trees to create shady riparian canopies. These canopies help cool the water and shade out less desirable species of plants, which can catch debris and reduce the streams’ water-carrying capacity. If necessary, we will remove some non-canopy forming trees such as arroyo willows as well as certain dense shrubs such as non-native and invasive blackberries. Sediment removal activities include planting native trees, shrubs, and some aquatic plants according to a certain pattern to establish canopy while maintaining channel capacity. The Sonoma County Youth Ecology Corps (SCYEC), a workforce training and ecosystem education program aimed at educating youth and young adults in environmental stewardship and restoration, will be working with the SMP this summer. The SCYEC provides youth and young adults paychecks, valuable work experience, environmental education, and the opportunity to contribute to their community through ongoing outdoor experiences. Below is the list of streams the Water Agency will be maintaining this summer. For a more detailed list, map of locations, and information on stream maintenance, visit www.sonomacountywater.org. -
Dear Friends, Sonoma County Is Celebrating the Winter and Spring Rains Which Have Left Our Rivers and Creeks with Plenty of Clea
This picture of Mark West creek was taken in April by our intern, Nick Bel. Dear Friends, Sonoma County is celebrating the winter and spring rains which have left our rivers and creeks with plenty of clear clean water going into summer. Many of CCWI’s water monitors have noted that local rivers and creeks have more water and are more beautiful than they have been in the past several years. This is a very promising start to the summer season, but we should not let our guard down just yet. Several years of drought have left us with a shortage of water in many reservoirs so we must still be conscious of how we use and protect this precious resource. CCWI has a new program Director! Art Hasson joined the Community Clean Water Institute in 2008 as an intern and volunteer water monitor. Art has a business degree from the State University of New York, which he has put to good use as our new program director. He has updated our water quality database engaged in field work, performed flow studies and bacterial analysis for the past two years. Art is focused on protecting our public health through the preservation of our waterways. CCWI would like to thank outgoing program director Terrance Fleming for his hard work and valuable contributions to protect water resources. We wish him the very best in his future endeavors. CCWI would like to thank our donors for their support in building our online database interactive database. It contains nine years of data that CCWI volunteer water monitors have collected on local creeks and streams in and around Sonoma County. -

Salmon and Steelhead in Your Creek: Restoration and Management of Anadromous Fish in Bay Area Watersheds
Salmon and Steelhead in Your Creek: Restoration and Management of Anadromous Fish in Bay Area Watersheds Presentation Summaries (in order of appearance) Gary Stern, National Marine Fisheries Service Steelhead as Threatened Species: The Status of the Central Coast Evolutionarily Significant Unit Under the federal Endangered Species Act (ESA), a "species" is defined to include "any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature." To assist NMFS apply this definition of "species to Pacific salmon stocks, an interim policy established the use of "evolutionarily significant unit (ESU) of the biological species. A population must satisfy two criteria to be considered an ESU: (1) it must be reproductively isolated from other conspecific population units; and (2) it must represent an important component in the evolutionary legacy of the biological species. The listing of steelhead as "threatened" in the California Central Coast resulted from a petition filed in February 1994. In response to the petition, NMFS conducted a West Coast-wide status review to identify all steelhead ESU’s in Washington, Oregon, Idaho and California. There were two tiers to the review: (1) regional expertise was used to determine the status of all streams with regard to steelhead; and (2) a biological review team was assembled to review the regional team's data. Evidence used in this process included data on precipitation, annual hydrographs, monthly peak flows, water temperatures, native freshwater fauna, major vegetation types, ocean upwelling, and smolt and adult out-migration (i.e., size, age and time of migration). Steelhead within San Francisco Bay tributaries are included in the Central California Coast ESU. -

MEMORANDUM DATE: August 31
MEMORANDUM DATE: August 31, 2017 Project No.: 592-10-16-05 SENT VIA: EMAIL TO: Harish Bagha, Grant Manager State Water Board Division of Financial Assistance Kari Holzgang, Program Analyst State Water Board Division of Financial Assistance FROM: Millicent Cowley-Crawford, Russian River Watershed Association Jarod Thiele, Grant Contact, City of Ukiah REVIEWED BY: Elizabeth Drayer, PE, RCE #46872 SUBJECT: Task 4.3 Description of Approach to Addressing Water Quality The Russian River Watershed Association (RRWA) has prepared this memorandum to provide a description of the approach to address water quality requirements in the Russian River Storm Water Resource Plan (SWRP). The approach identifies activities generating or contributing to polluted runoff or that impair beneficial uses of storm water and dry weather runoff and outlines potential strategies to address these issues. In addition, the consistency of the SWRP with applicable water quality regulatory requirements is outlined. STORM WATER RESOURCE PLANNING AREA The Planning Area of the Russian River SWRP has been determined in the Task 3.2 Planning Area and Watershed Descriptions memorandum dated June 9, 2017. As a brief overview, for the purposes of the SWRP, the Russian River watershed includes three divisions with nine U.S. Geologic Survey (USGS) Hydrologic Unit Code (HUC) 10 watersheds, and 43 HUC 12 subwatersheds. With twenty major tributaries and covering an area of 950,360 acres, the Russian River runs a length of 110 miles and is susceptible to water quality threats both in its tributaries and mainstem. The Russian River Watershed Association complies with ADA requirements and will attempt to reasonably accommodate individuals with disabilities upon request. -

Historical Distribution and Current Status of Steelhead/Rainbow Trout (Oncorhynchus mykiss) in Streams of the San Francisco Estuary, California Robert A. Leidy, Environmental Protection Agency, San Francisco, CA Gordon S. Becker, Center for Ecosystem Management and Restoration, Oakland, CA Brett N. Harvey, John Muir Institute of the Environment, University of California, Davis, CA This report should be cited as: Leidy, R.A., G.S. Becker, B.N. Harvey. 2005. Historical distribution and current status of steelhead/rainbow trout (Oncorhynchus mykiss) in streams of the San Francisco Estuary, California. Center for Ecosystem Management and Restoration, Oakland, CA. Center for Ecosystem Management and Restoration SONOMA COUNTY Petaluma River Watershed The Petaluma River watershed lies within portions of Marin and Sonoma Counties. The river flows in a northwesterly to southeasterly direction into San Pablo Bay. Petaluma River In a 1962 report, Skinner indicated that the Petaluma River was an historical migration route and habitat for steelhead (Skinner 1962). At that time, the creek was said to be “lightly used” as steelhead habitat (Skinner 1962). In July 1968, DFG surveyed portions of the Petaluma River accessible by automobile from the upstream limit of tidal influence to the headwaters. No O. mykiss were observed (Thomson and Michaels 1968d). Leidy electrofished upstream from the Corona Road crossing in July 1993. No salmonids were found (Leidy 2002). San Antonio Creek San Antonio Creek is a tributary of Petaluma River and drains an area of approximately 12 square miles. The channel is the border between Sonoma and Marin Counties. In a 1962 report, Skinner indicated that San Antonio Creek was an historical migration route for steelhead (Skinner 1962). -
