  • ATTACHMENT B Dams and Reservoirs Along the Lower
    ATTACHMENTS ATTACHMENT B Dams and Reservoirs Along the Lower Colorado River This attachment to the Colorado River Interim Surplus Criteria DEIS describes the dams and reservoirs on the main stream of the Colorado River from Glen Canyon Dam in Arizona to Morelos Dam along the international boundary with Mexico. The role that each plays in the operation of the Colorado River system is also explained. COLORADO RIVER INTERIM SURPLUS CRITERIA DRAFT ENVIRONMENTAL IMPACT STATEMENT COLORADO RIVER DAMS AND RESERVOIRS Lake Powell to Morelos Dam The following discussion summarizes the dams and reservoirs along the Colorado River from Lake Powell to the Southerly International Boundary (SIB) with Mexico and their specific roles in the operation of the Colorado River. Individual dams serve one or more specific purposes as designated in their federal construction authorizations. Such purposes are, water storage, flood control, river regulation, power generation, and water diversion to Arizona, Nevada, California, and Mexico. The All-American Canal is included in this summary because it conveys some of the water delivered to Mexico and thereby contributes to the river system operation. The dams and reservoirs are listed in the order of their location along the river proceeding downstream from Lake Powell. Their locations are shown on the map attached to the inside of the rear cover of this report. Glen Canyon Dam – Glen Canyon Dam, which formed Lake Powell, is a principal part of the Colorado River Storage Project. It is a concrete arch dam 710 feet high and 1,560 feet wide. The maximum generating discharge capacity is 33,200 cfs which may be augmented by an additional 15,000 cfs through the river outlet works.

  • 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.

  • Section 5.15: Water Supply
    General Plan Update Section 5.15: Water Supply This section analyzes projected impacts to water supplies and distribution systems that may result from the implementation of the proposed General Plan 2035. The purpose of this analysis is to document and describe the existing water supply, water consumption, and distribution infrastructure in the City of Murrieta, and to evaluate impacts associated with buildout of the proposed General Plan 2035. This section is based upon information from the Eastern Municipal Water District (refer to Appendix L1); Elsinore Valley Water District (refer to Appendices M1, M2, and M3); Rancho California Water District (refer to Appendices N1, N2, and N3); and Western Municipal Water District (refer to Appendices O1 and O2). The Clean Water Act (CWA) is a Federal law intended to protect surface waters of the United States (U.S.), which include lakes, rivers, coastal wetlands, and “waters of the U.S.” The CWA regulates all discharges to waters, which are considered illegal unless authorized by an appropriate permit. Discharge of dredged and fill materials, construction-related storm water discharges, and other activities that may result in discharges of pollutants to waters of the U.S. are regulated by the permit. If waters of the U.S. are located on a project site, the project is likely to discharge to them, due to site topography and/or drainage characteristics. Potential discharges to such waters would be considered an impact, and the applicant would be required to obtain a CWA Section 401 Water Quality Certification from the appropriate Regional Water Quality Control Board (RWQCB).

  • Environmental Setting 2
    2.0 Environmental Setting 2 Chapter 2 Environmental Setting 2.1 Planning Context 2.1.1 Project Location The city of Moreno Valley (city) is located within the northwestern portion of Riverside County in the southern Inland Empire portion of the state of California. Moreno Valley is located approximately 63 miles east of downtown Los Angeles, 49 miles east of the city of Irvine, and 43 miles west of the city of Palm Springs. State Route 60 (SR-60), which runs in an east and west direction through the northern portion of Moreno Valley (east and west direction), and Interstate 215 (I-215), which runs in proximity to the westerly city limits (north and south direction), serve to connect the city to other communities throughout the southern California region. The city is accessible via public transportation by rail, through Metrolink located approximately one-half mile west of the city limits, and the city is accessible via aircraft at the Inland Port Airport located at the March Air Reserve Base (MARB), which is situated south and west of the city limits. The city’s picturesque valley setting is bounded to the north by the Box Springs Mountains, the Badlands to the east, and the mountains of the Lake Perris Recreation Area, Mystic Lake floodplain, and San Jacinto Wildlife Area to the south. The city is also bounded by MARB to the southwest and the city of Riverside to the west. Moreno Valley is a diverse and growing community of approximately 207,000 people. It has a relatively young and dynamic majority Latino population.

  • Mr. George Colangeli, General Manager Palo Verde Valley Transit Agency 415 N
    Salud Mr. George Colangeli, General Manager Palo Verde Valley Transit Agency 415 N. Main Street Blythe, CA. 92225 Facsimile number 760-922-0491 Dear Mr. Colangeli: The City of Blythe is pleased to support the Blythe Wellness Express 5310 grant application submitted by the Palo Verde Valley Transit Agency (PVVTA) for funding to support this specialized transportation project. With this funding PVVTA will able to provide safe transportation to and from the Coachella Valley area's hospitals and clinics. Blythe Wellness Express will fill a critical transportation gap for Blythe residents to access health care. The planned lifeline transportation service, operating two to three days weekly, will travel to the Coachella Valley’s three hospitals and selected medical clinics more than 100 miles to the west. Currently there is no public transportation between Blythe and the Coachella Valley, with very limited Greyhound service. With temperatures in excess of 110 degrees in our summer months it is the City's belief that having a well purposed means of transportation with a bus designed to make the more than 200 mile trips to and from the Coachella Valley is a much needed addition to PVVTA's Fleet. Blythe is an isolated rural community in the Palo Verde Valley of the Lower Colorado River Valley region, part of the Colorado Desert, and does not score well on numerous health indicators. Additionally, Blythe is a designated Mental Health and Primary Care Health Professional Shortage Area (HPSA). We expect that better access to health care specialists, treatments and facilities in the Coachella Valley, via the Blythe Wellness Express, will do much to improve Blythe residents’ health.
