Watershed Summaries
Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working

San Diego Bay CCA Factsheet 2019
CCA #122 San Diego Bay Critical Coastal Area DESCRIPTION This Critical Coastal Area (CCA) watershed drains into San Diego Bay in San Diego County, the third largest sheltered bay on the California coast. Many waterways flow into the bay. The largest is the Sweetwater River in the southern half of the bay, terminating in Sweetwater Marsh. The Otay River also terminates in saltwater marsh at the southern tip of the bay. Other notable creeks include Telegraph Canyon Creek, Paleta Creek, Chollas Creek, Paradise Creek, and Switzer San Diego Bay, Creek. Coronado Side All of these waterways begin in the Cuyamaca Mountains, (Copyright © 2006 Kenneth and flow through densely urbanized areas before entering & Gabrielle Adelman, the bay. There are also numerous flood control and water California Coastal Records supply dams along the larger tributaries. Historically, San Project). Diego Bay was one of the primary outflows of the San Diego For more photos, see the River (along with Mission Bay), but the river’s estuary was California Coastal Records straightened with dredging and levee projects at the end of Project. the 19th century. San Diego Bay is bordered by many large urban areas, including the cities of San Diego, National City, Chula Vista, Imperial Beach, and Coronado. The downtown commercial center of the City of San Diego is along the north side of the bay, and the San Diego International Airport is nearby. Residences in Coronado (such as the Coronado Cays) line the Silver Strand, the strip of sand between the south bay and Coronado Island. The Coronado Bridge roughly bisects the bay, and provides auto access to the peninsula.

Sweetwater Dam: Then and Now
Sweetwater Dam: Then and Now By Richard A. Reynolds August 2, 2008 Sweetwater Dam: Then and Now Sweetwater Dam is a very important element of the water supply to the South Bay communities. It is the key to treatment and distribution of local runoff and imported supplies. This year is the 120lh in its long history in this important role. The dam, as you will see in this paper, has withstood many challenges and trials from storms that brought runoff flows from the watershed to the 100-year storm levels. A major storm in 1895, only seven years after completion of the dam, overtopped the dam by nearly two feet. This was proof of the core strength of the gravity arch configuration to withstand hydraulic forces. Sweetwater Dam, when completed in its initial configuration on April 7, 1888 (Figure 1), represented the latest design concept for masonry dams and, at its original completed height of 90 feet, was the tallest masonry, gravity arch dam in the United States. It was completed just in time to quench the thirst of South Bay residents and to ensure their hopes for land speculation, municipal growth and agricultural success. In his Nobel Prize winning novel, "East of Eden", John Steinbeck was describing people in California (albeit, in the Salinas Valley) and their awareness of water conditions in general when he wrote, "And it never failed that during the dry years the people forgot about the rich years, and during the wet years they lost all memory of the dry years. It was always that way." And so it was here in the South Bay.

Prehistoric Fishing on the San Diego Coast
Prehistoric Fishing on the San Diego Coast Anna C. Noah Abstract In general, archaeologists working in San Diego County have not considered fishing to have been a regionally important prehistoric activity. However, a review of published and gray literature has revealed that fishing has been an important part of the prehistoric economy for at least the last 8000 years. A synthesis of previous work provides new insights with respect to division of labor, social organization, and intensification. It is suggested that future archaeo- logical research in San Diego County be designed to capitalize on the important potential of fish fauna and fishing gear to increase our understanding of prehistoric cultures on the San Diego coast. Introduction In a recent article, Raab et al. remark that “[f]ishing is one of the most extensively investi- gated prehistoric subsistence activities in coastal southern California (1995b:11).” The authors cite ten references supporting their comment. While there is no argument regarding the broad accuracy of their statement, what is remarkable in examining their references is the dearth of published work pertaining to San Diego County, despite the fact that the region embraces an approximately 130-kilometer-long stretch of the southern California coastline. The goals of this paper are to summarize and synthesize the archaeological literature pertain- ing to prehistoric fishing in San Diego County and to consider how the archaeological record pertaining to fish exploitation might contribute to our understanding of regional prehistory. Background The published literature discussing prehistoric fishing in San Diego County is limited prima- rily to work conducted during the early 1960s.

Draft Guidelines for Greening San Diego Program
SAN DIEGO RIVER CONSERVANCY’S GREENING SAN DIEGO PROGRAM DRAFT GRANT PROGRAM GUIDELINES MAY 14, 2020 San Diego River Conservancy 11769 Waterhill Road Lakeside, CA 92040 FOR PUBLIC INPUT I. INTRODUCTION A. The San Diego River Conservancy The San Diego River Conservancy (“Conservancy”) is a state agency, established in 2002, to work specifically within the San Diego River watershed to implement multi- benefit projects that protect and enhance the San Diego River and its connected resources. The San Diego River Conservancy Act, the Conservancy’s enabling legislation, is contained in Division 22.9 of the Public Resources Code. The Act authorizes the Conservancy to undertake projects and award grants to achieve the goals set forth in Division 22.9. The Conservancy works along the entire length of the San Diego River, from its mouth in the City of San Diego at Ocean Beach to its headwaters in the mountains near Julian, California. This area also includes all of the contributing area to the San Diego River (its “watershed”) consisting of several streams, reservoirs, wetlands, estuary and uplands. A map of the Conservancy’s jurisdiction can be viewed at www.sdrc.ca.gov. Senate Bill 1367 (2018), codified as Pub. Resources Code, Division 22.9, Chapter 4.5 (commencing with Section 32659), authorizes the Conservancy to convene advisory panels for the Otay River, Sweetwater River and Tijuana River and assist in identifying and pursuing grant funding to restore and enhance natural, historical, cultural, educational and recreational resources along the rivers and enhance public access to the rivers watersheds. The Conservancy’s adopted Strategic Plan 2018-2023 http://sdrc.ca.gov/webmaster/arc/docs/StratPlan_update_2018-2023_Final.pdf and the San Diego River Conservancy Act, identifies the Conservancy’s goals and objectives.

Hydrology and Water Quality
Section 2.5 Hydrology and Water Quality This section describes the hydrology and water quality conditions in the County and the regulatory framework applicable to hydrology and water quality. It also assesses the potential impacts on hydrology and surface and groundwater quality that could result from project implementation, and presents mitigation measures that would reduce potentially significant impacts. Water resources can be classified into two categories: (1) surface water, which collects in streams, rivers, lakes, and reservoirs; and (2) groundwater, which resides in subsurface aquifers. This section deals with surface water. Groundwater resources are discussed in Section 2.8, Water Supply and Groundwater. Topics related to floods, levees, or dams, and seiche, tsunami, or mudflow are discussed in Chapter 3, Environmental Effects Found Not to be Significant. 2.5.1 Existing Conditions 2.5.1.1 Surface Water Hydrology Surface water bodies in the County (e.g., estuaries, lagoons, bays, lakes, reservoirs, rivers, and creeks) capture the flow of the region’s water runoff, often combining natural runoff with imported water. Many of these water bodies support natural habitat and recreational areas, and serve as storage reservoirs for the County’s water supply. The San Diego region is divided into two hydrologic basins (the South Coast Basin and the Colorado River Basin) by the northwest-trending Peninsular Range. The County is divided into two hydrologic regions: (1) the San Diego Hydrologic Region, which drains in a westerly direction toward the Pacific Ocean and encompasses most of the County, parts of southwestern Riverside County, and southwestern Orange County; and (2) the Colorado Hydrologic Region, which drains in an easterly direction toward the desert and Colorado River basin.
