  • Physical Setting
    Physical Setting Dunne and Leopold (1978) define a watershed as an area of land that drains water, sediment, and dissolved materials to a common outlet at some point along a stream channel. The Santa Ana River (SAR) Watershed, depicted in Figure 3-1, drains a 2,650 square-mile area. The watershed is home to over 6 million people and includes the major population centers of parts of Orange, Riverside, and San Bernardino Counties, as well as a sliver of Los Angeles County. The Santa Ana River flows over 100 miles and drains the largest coastal stream system in Southern California. It discharges into the Pacific Ocean at the City of Huntington Beach. The total length of the SAR and its major tributaries is about 700 miles. 1 | W a t e r s h e d S e t t i n g Figure 3-1 Santa Ana Integrated Regional Water Management Region The watershed boundaries nearly match the boundaries of the Santa Ana Regional Water Quality Control Board, an organization with whom the Santa Ana Watershed Project Authority (SAWPA) has worked closely with for many years. In addition, its boundaries match the Integrated Regional Water Management (IRWM) region and the recognized Santa Ana Funding Area, as defined by the Proposition 84 IRWM program. Although there are many sub-watershed planning efforts, One Water One Watershed 2.0 (OWOW) attempts to bring all these efforts, as well as all different jurisdictions in the watershed, into a single watershed-wide vision. Over the years, SAWPA has participated in the development of sub-regional IRWM plans, with the understanding that such plans would be complementary to OWOW.

  • Seal Beach NWR Final
    U.S. Fish & Wildlife Service Seal Beach National Wildlife Refuge Final Comprehensive Conservation Plan Comprehensive Conservation Plans provide long-term guidance for management deci- sions and set forth goals, objectives, and strategies needed to accomplish refuge purposes and identify the Service’s best estimate of future needs. These plans detail program planning levels that are sometimes substantially above current budget allocations and, as such, are primarily for Service strategic planning and program prioritization purposes. The plans do not constitute a commitment for staffing increases, operational and mainte- nance increases, or funding for future land acquisition. U.S. Fish & Wildlife Service Seal Beach National Wildlife Refuge Final Comprehensive Conservation Plan May 2012 Vision Statement Tidal channels meandering through a sea of cordgrass deliver moisture and nourishment to support a healthy marsh ecosystem. As the quiet calm of the morning is interrupted by the clacking of a light-footed clapper rail, school children and other visitors, standing on the elevated observation deck, point with excitement in the direction of the call hoping for a glimpse of the rare bird. Shorebirds dart from one foraging area to another feasting on what appears to be an endless supply of food hidden within the tidal flats. California least terns fly above the tidal channels searching for small fish to carry back to their nests on NASA Island. A diverse array of marine organisms, from tube worms and sea stars to rays and sharks, and even an occasional green sea turtle, thrive within the tidal channels and open water areas of the Refuge’s diverse marsh complex, while Nelson’s sparrows and other upland birds find food and shelter within the native upland vegetation that borders the marsh.
