    Overview of Management and Restoration Activities in the Salton Sea name redacted Specialist in Natural Resources Policy May 26, 2004 Congressional Research Service 7-.... www.crs.gov RL31820 CRS Report for Congress Prepared for Members and Committees of Congress Overview of Management and Restoration Activities in the Salton Sea Summary The Salton Basin in southern California has supported many lakes and water bodies throughout its geological history. The most recent inland water body in the Basin is the Salton Sea, which was created from a levee break in 1905. The Salton Sea is the largest inland water body in California. In the past several decades the salinity of the Sea has been increasing, and is now considered a significant threat to the health of the current Salton Sea ecosystem. Ecosystem changes in the Sea were exemplified by several large die-offs of fish and birds that inhabit the Sea. Some of these events included endangered species such as the brown pelican. The Sea receives most of its water from agricultural drainage originating in the Imperial and Coachella Valleys in California. When water transfers from agricultural lands in these valleys to municipal water districts in San Diego were proposed to reduce California’s reliance on water from the Colorado River, concerns about the environmental impacts of these transfers on the Sea surfaced. The proposed water transfers would have resulted in less water flowing into the Salton Sea, which according to some scientists would increase the rate of evaporation in the Sea so that salinity levels would be lethal to most fish and wildlife in less than 10 years.

  • Chapter 1: Introduction
    1. Introduction 1.1 Introduction and Background The Sonny Bono Salton Sea National Wildlife Refuge Complex (Complex or NWRC) consists of the Sonny Bono Salton Sea National Wildlife Refuge (NWR) and Coachella Valley NWR. Although both Refuges are located within the 8,000-square-mile Salton Basin of the Colorado Desert (Figure 1-1), the purposes of these two Refuges are as different as the habitats and species they protect. The Sonny Bono Salton Sea NWR, which consists of 37,660 acres, is situated at the south end of the Salton Sea, about 20 miles north of El Centro in Imperial County, California (Figure 1-2). The purpose of this Refuge is to protect and manage habitat to support migratory birds, particularly waterfowl, and other wildlife. Thousands of shorebirds, seabirds, and waterfowl stop-over or winter at the Salton Sea (Mark Stewart/USFWS) About 75 miles to the northwest is the 3,577-acre Coachella Valley NWR, located 10 miles east of Palm Springs in Riverside County, California (Figure 1-3). The purpose of this Refuge is to protect and contribute to the long-term survival of the federally threatened Coachella Valley fringe-toed lizard (Uma inornata) and federally endangered Coachella Valley milk-vetch (Astragalus lentiginosus var. coachellae), both endemic to the active sand habitats in the Coachella Valley. The U.S. Fish and Wildlife Service (Service) prepared this Comprehensive Conservation Plan (CCP) for the Sonny Bono Salton Sea NWR and Coachella Valley NWR to guide the management of these Refuges over the next 15 years. The CCP describes future Refuge conditions and provides long-range management direction for achieving the purposes for which each Refuge was established.

  • Sonny Bono Salton Sea National Wildlife Refuge Complex
    Appendix J Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex Appendix J: Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex The following sections describe the cultural setting in and around the two refuges that constitute the Sonny Bono Salton Sea National Wildlife Refuge Complex (NWRC) - Sonny Bono Salton Sea NWR and Coachella Valley NWR. The cultural resources associated with these Refuges may include archaeological and historic sites, buildings, structures, and/or objects. Both the Imperial Valley and the Coachella Valley contain rich archaeological records. Some portions of the Sonny Bono Salton Sea NWRC have previously been inventoried for cultural resources, while substantial additional areas have not yet been examined. Seventy-seven prehistoric and historic sites, features, or isolated finds have been documented on or within a 0.5- mile buffer of the Sonny Bono Salton Sea NWR and Coachella Valley NWR. Cultural History The outline of Colorado Desert culture history largely follows a summary by Jerry Schaefer (2006). It is founded on the pioneering work of Malcolm J. Rogers in many parts of the Colorado and Sonoran deserts (Rogers 1939, Rogers 1945, Rogers 1966). Since then, several overviews and syntheses have been prepared, with each succeeding effort drawing on the previous studies and adding new data and interpretations (Crabtree 1981, Schaefer 1994a, Schaefer and Laylander 2007, Wallace 1962, Warren 1984, Wilke 1976). The information presented here was compiled by ASM Affiliates in 2009 for the Service as part of Cultural Resources Review for the Sonny Bono Salton Sea NWRC. Four successive periods, each with distinctive cultural patterns, may be defined for the prehistoric Colorado Desert, extending back in time over a period of at least 12,000 years.

A Salton Sea Chronology A Salton Sea Chronology (Prehistory-2015) Year Events 10,000 BC First recorded human habitation in the Salton Basin. (Approx) 700 AD Lake Cahuilla is formed in the Salton Basin when the Colorado River silts (Flood!) up its outlet to the Gulf of California and swings northward. Lake Cahuilla is subject to multiple wet and dry cycles over intervening years. 1500 Large inflow of the Colorado River water fills Lake Cahuilla to create a waterbody 26 (Flood!) times the size of the current Salton Sea. (The calcareous water line remains visible on the northwest mountains in the present day). 1840-1891 Multiple flood events from the Colorado River are recorded in the Salton Basin forming ephemeral lakes up to 100,000 acres. 1876 Executive Order of May 15, 1876, establishes the Torres Martinez Desert Cahuilla Indian Reservation with a grant of 640 acres (Torres Martinez Compact, 2003). 1891 Executive Order of December 19, 1891, pursuant to the Mission Indian Relief Act of 1891, expands the Torres Martinez Desert Cahuilla Indian Reservation approximately 12,000 acres on the northern side of the Salton Basin. 1892 New Liverpool Salt Company mines salt from a salt marsh centered west of the railroad station named “Salton”. 1901 California Development Company is contracted by a private entity to build a canal (the Alamo Canal) to deliver water by gravity flow from the Colorado River to irrigate the Imperial Valley.
