San Mateo County
Steelhead/rainbow trout resources of San Mateo County San Pedro San Pedro Creek flows northwesterly, entering the Pacific Ocean at Pacifica State Beach. It drains a watershed about eight square miles in area. The upper portions of the drainage contain springs (feeding the south and middle forks) that produce perennial flow in the creek. Documents with information regarding steelhead in the San Pedro Creek watershed may refer to the North Fork San Pedro Creek and the Sanchez Fork. For purposes of this report, these tributaries are considered as part of the mainstem. A 1912 letter regarding San Mateo County streams indicates that San Pedro Creek was stocked. A fishway also is noted on the creek (Smith 1912). Titus et al. (in prep.) note DFG records of steelhead spawning in the creek in 1941. In 1968, DFG staff estimated that the San Pedro Creek steelhead run consisted of 100 individuals (Wood 1968). A 1973 stream survey report notes, “Spawning habitat is a limiting factor for steelhead” (DFG 1973a, p. 2). The report called the steelhead resources of San Pedro Creek “viable and important” but cited passage at culverts, summer water diversion, and urbanization effects on the stream channel and watershed hydrology as placing “the long-term survival of the steelhead resource in question”(DFG 1973a, p. 5). The lower portions of San Pedro Creek were surveyed during the spring and summer of 1989. Three O. mykiss year classes were observed during the study throughout the lower creek. Researchers noticed “a marked exodus from the lower creek during the late summer” of yearling and age 2+ individuals, many of which showed “typical smolt characteristics” (Sullivan 1990). -
Historical Status of Coho Salmon in Streams of the Urbanized San Francisco Estuary, California
CALIFORNIA FISH AND GAME California Fish and Game 91(4):219-254 2005 HISTORICAL STATUS OF COHO SALMON IN STREAMS OF THE URBANIZED SAN FRANCISCO ESTUARY, CALIFORNIA ROBERT A. LEIDY1 U. S. Environmental Protection Agency 75 Hawthorne Street San Francisco, CA 94105 [email protected] and GORDON BECKER Center for Ecosystem Management and Restoration 4179 Piedmont Avenue, Suite 325 Oakland, CA 94611 [email protected] and BRETT N. HARVEY Graduate Group in Ecology University of California Davis, CA 95616 1Corresponding author ABSTRACT The historical status of coho salmon, Oncorhynchus kisutch, was assessed in 65 watersheds surrounding the San Francisco Estuary, California. We reviewed published literature, unpublished reports, field notes, and specimens housed at museum and university collections and public agency files. In watersheds for which we found historical information for the occurrence of coho salmon, we developed a matrix of five environmental indicators to assess the probability that a stream supported habitat suitable for coho salmon. We found evidence that at least 4 of 65 Estuary watersheds (6%) historically supported coho salmon. A minimum of an additional 11 watersheds (17%) may also have supported coho salmon, but evidence is inconclusive. Coho salmon were last documented from an Estuary stream in the early-to-mid 1980s. Although broadly distributed, the environmental characteristics of streams known historically to contain coho salmon shared several characteristics. In the Estuary, coho salmon typically were members of three-to-six species assemblages of native fishes, including Pacific lamprey, Lampetra tridentata, steelhead, Oncorhynchus mykiss, California roach, Lavinia symmetricus, juvenile Sacramento sucker, Catostomus occidentalis, threespine stickleback, Gasterosteus aculeatus, riffle sculpin, Cottus gulosus, prickly sculpin, Cottus asper, and/or tidewater goby, Eucyclogobius newberryi. -
San Mateo County Watershed Data in a GIS
San Mateo County Watershed Data in a GIS Introduction The San Mateo Countywide Water Pollution Prevention Program (Program) performs Watershed Assessment and Monitoring (WAM) component activities in compliance with its municipal stormwater NPDES permit requirements. In the past, a consistent countywide watershed boundary data layer has not been available to meet Program needs for mapping and analyzing watershed-related data. As a result, the Program has previously utilized the best existing available data sets and/or developed new data to meet the objectives of specific individual projects. For example, creek location and watershed boundary data were developed to characterize imperviousness and channel modifications in seventeen watersheds in San Mateo County (STOPPP 2002). In another example, Program staff compiled existing countywide watershed data and developed new data needed to identify watershed areas considered exempt from Hydromodification Management Plan (HMP) requirements (STOPPP 2005). The Program previously identified two major information gaps in digital watershed boundary data: 1) limited storm drain catchment data were available for urban areas and 2) consistent countywide watershed data layers were not available (STOPPP 2005). Recent development of watershed data in urbanized portions of San Mateo County has provided an opportunity to address these information gaps. This memo describes the methods used by Program staff to create a consistent countywide watershed data layer that includes delineation of storm drain catchments in urban areas. Consistent watershed and creek data set will assist Program staff in watershed characterization and the identification and prioritization of potential future monitoring and watershed assessment activities. Background In 1999, the State of California developed a statewide watershed data layer entitled the California Interagency Watershed Map (Calwater). -

May 2008. 4.7.1 Setting a. Physical Setting. Drainage. The City of Scotts Valley occupies the valley of Carbonera Creek and its main tributary to the north, Bean Creek. The project site is located within both the watershed of Carbonera Creek and Bean Creek (see Figure 4.7-1). Carbonera Creek is a tributary of the San Lorenzo River system, which drains south from the Santa Cruz Mountains into the Monterey Bay at the City of Santa Cruz. The San Lorenzo River watershed drains approximately 137 square miles, and its principal tributaries include Boulder Creek, Kings Creek, Bear Creek, Newell Creek, Zayante Creek, Bean Creek, and Branciforte Creek. The Carbonera Creek watershed drains 3.6 square miles at United States Geological Survey (USGS) gauge near the Scotts Valley Water District (SVWD) southern boundary. Unlike Bean Creek, Carbonera Creek typically becomes dry or near dry during the summer months. The creek flows generally southwest from its headwaters in the Santa Cruz Mountains, and discharges to Branciforte Creek in the City of Santa Cruz. -
Understanding the San Lorenzo River Watershed by Lee Summers
Understanding the San Lorenzo River Watershed By Lee Summers Water is the drink of life that pours through our veins, cradles us as babes in the womb, carves valleys and mountains, cleans our air and keeps our planet green and growing. About 71 percent of the earth’s surface is covered with water. Of that, about 2½ percent is fresh water and only about 1.2 percent of fresh water can we easily access, treat, and drink.1 What’s more, about 60 percent of the human body is water. It comes in quite handy as cellular building material; to regulate our temperature; transport food; flush waste; absorb shock to the brain, spine, and fetus; and lubricate joints.2 We can find water as a liquid, gas and solid. Its solid form is less dense than liquid, which allows lakes to freeze from the top down. It dissolves substances better than any other liquid, which means it easily transports nutrients through a body. It absorbs a lot of heat before it gets hot, so it keeps the air temperature more constant, especially near the coast. It sticks to itself, which allows it to ball into drops as well as get pulled up the tallest redwood trees. In fact, if we weren’t surrounded by it our entire lives, it would amaze us. Water is essential for life on this planet, yet most people have no idea where their water comes from when they turn on the faucet. If they really understood, they would likely never take water for granted again. -
Report of Water Quality Monitoring for Bacteria Indicators in the Lower San Lorenzo River Watershed, 2014 and 2016
Report of Water Quality Monitoring for Bacteria Indicators in the Lower San Lorenzo River Watershed, 2014 and 2016 Prepared for the San Lorenzo River Alliance, Water Quality Working Group, with participants from: City of Santa Cruz Public Works Department City of Santa Cruz Water Department County of Santa Cruz Department of Public Works County of Santa Cruz Department of Environmental Health Services Central Coast Regional Water Quality Control Board Coastal Watershed Council Surfrider Foundation Prepared by: Armand Ruby, Technical Director, Coastal Watershed Council Alev Bilginsoy, River Scientist, Coastal Watershed Council December 29, 2017 INTRODUCTION The Water Quality Working Group of the San Lorenzo River Alliance (SLRA) was first assembled in 2013 to help address water quality issues in the San Lorenzo River and its tributaries. Working Group participants include personnel with water quality expertise from: City of Santa Cruz Public Works and Water Departments, County of Santa Cruz Environmental Health Services and Public Works, Central Coast Regional Water Quality Control Board, and Nonprofit organizations Surfrider Foundation and Coastal Watershed Council. The Working Group has taken a collaborative approach to improving water quality in the San Lorenzo River watershed. The initial focus of the Working Group’s activity has been to address impairment of river water quality by fecal indicator bacteria. The reasons for this focus are: 1. The SLRA wishes to improve the general quality and beneficial uses in the San Lorenzo River, and 2. The SLRA seeks to participate with other stakeholders and help municipalities in response to the impairment of beneficial uses of the river, as described in the San Lorenzo River Watershed Pathogen Total Maximum Daily Load (TMDL) regulation (Central Coast Water Board Resolution R3-2009-0023). -

San Mateo County: Recreation Goals, Needs, and Trends; Facilities Inventory
SAN MATEO COUNTY: RECREATION GOALS, NEEDS, AND TRENDS; FACILITIES INVENTORY BACKGROUND California SCORP (2002) San Mateo County is the 5th most urbanized county in the state at 1,575 people per square mile. San Francisco is the most densely populated at 16,526 people per square mile. The Public Opinions and Attitudes Survey (1997) showed that Californian’s top two recreational activities (in terms of participation) were walking for fitness and fun and visiting museums and historic sites. Picnicking and trail hiking were ranked 7th and 8th, respectively. Camping in developed sites and camping in primitive areas were ranked 13th and 20th (out of 20), respectively. However, when asked if they would increase their participation if good recreational opportunities became available, latent demand for camping in developed sites and trail hiking was extremely high, followed by wildlife viewing. People also showed support for government spending on those same activities. The results of the same survey administered in 2002 showed very similar results. When the participation data are combined with data on latent demand and public support, the top five most important recreational activities were 1) walking for fitness and fun, 2) beach activities, 3) wildlife viewing, 4) driving for pleasure, and 5) trail hiking. California State Parks McNee Ranch State Park contains 2 parking spaces as well as on-street parking, 1 portable restroom, and multi-use trails with 1 bench. Graywhale Cove State Beach contains 40 parking spaces, pedestrian trails, 2 portable restrooms, and 1 concession stand. San Mateo County Parks & Recreation Mid-Coast Recreational Needs Assessment (2002) The Mid-Coast area of San Mateo County encompasses an area of 6.1 square miles to the north of the City of Half Moon Bay.
