Cajalco Creek
Cajalco Canyon Creek is an ephemeral stream that flows through Cajalco Canyon in the Temescal Mountains of Riverside County, California, United States. It is a tributary to Temescal Wash, itself a tributary to the Santa Ana River. Cajalco is thought to be a Hispanic spelling of the word for "quail" in the languages of the Luiseño and Cahuilla who lived in the area. The word Cajalco is an acronym- California Jalisco Land Company of Los Angeles Course Cajalco Canyon Creek originally flowed down the northeast face of the Gavilan Hills of the Temescal Mountains at . It then turned northwest to take in waters from arroyos from Mead Valley and turned west down through the wide, gently sloping Cajalco Valley above Cajalco Canyon gathering waters from the Gavilan Plateau from Harford Spring Canyon at , and from other minor arroyos. Other small arroyos descended from heights to the north. It entered Temescal Wash at after descending through the steep narrow gorge of the Cajalco ...

Gavilan Plateau
Gavilan Plateau is a plateau in Riverside County, California. It lies at an elevation of 2083 feet on the north slope of the Temescal Mountains overlooking the Cajalco Valley south of Riverside, California. History The Gavilan Hills and Gavilan Plateau were a site of gold mining soon after the beginning of California Gold Rush: :"Many small mining claims and camps were established starting as early as the mid-1850s, mostly by Spanish-speaking individuals. Some familiar names such as Trujillo and Robidoux from the New Mexican colony of Agua Mansa, figured heavily in mining interests there. In fact, one of the main camps was called Rancho de los Trujillos, and it was mentioned frequently in the various claims filed during these years." In later years at the Gavilan Plateau, there was a small mining settlement of primarily Spanish speaking miners called Gavilan. Some English-speaking miners of the 1880s called it Cedar Flat. Subsequently, in 1891 M. C. Westbrook and Associates, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Riverside County, California
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Lake Mathews
Lake Mathews is a large reservoir in Riverside County, California, located in the Cajalco Canyon in the foothills of the Temescal Mountains. It is the western terminus for the Colorado River Aqueduct that provides much of the water used by the cities and water districts of the Metropolitan Water District of Southern California (MWD). The reservoir is fenced and closed to all public access. The lake is near the Riverside community of Lake Hills, Riverside County, Lake Hills, and is skirted by Cajalco Road on the south, El Sobrante Road on the north and east, and La Sierra Avenue on the west. La Sierra Avenue traverses the top of the west dike. The reservoir was constructed by building a large Embankment dam, earthfill dam across the northern side of the basin. Two smaller dams, called dikes, were built during the expansion to increase the lake's capacity. History Originally named the Cajalco Reservoir, the reservoir is now named after W.B. Mathews, an attorney who was a key arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado River Aqueduct
The Colorado River Aqueduct, or CRA, is a water conveyance in Southern California in the United States, operated by the Metropolitan Water District of Southern California. The aqueduct impounds water from the Colorado River at Lake Havasu on the California–Arizona border, west across the Mojave and Colorado deserts to the east side of the Santa Ana Mountains. It is one of the primary sources of drinking water for Southern California. Originally conceived by William Mulholland and designed by Chief Engineer Frank E. Weymouth of the MWD, it was the largest public works project in southern California during the Great Depression. The project employed 30,000 people over an eight-year period and as many as 10,000 at one time. The system is composed of two reservoirs, five pumping stations, of canals, of tunnels, and of buried conduit and siphons. Average annual throughput is . Route The Colorado River Aqueduct begins near Parker Dam on the Colorado River. There, the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". A quadrangle is defined by north and south boundaries of Circle of latitude, constant latitude (which are not great circles so are curved), and by east and west boundaries of constant longitude. From approximately 1947–1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetry, photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by d ...

Lake Elsinore
Lake Elsinore is a natural freshwater lake in Riverside County, California, United States, located east of the Santa Ana Mountains and fed by the San Jacinto River. Originally named ''Laguna Grande'' by Spanish explorers, it was renamed for the town of Elsinore, established on its northeastern shore on April 9, 1888. Lake water levels have fluctuated greatly from dry spells to flooding. Lake Elsinore was home to the Lake Shore Beach Club, an African American resort. Limnology Lake Elsinore is the largest natural freshwater lake in Southern California. With its own 750-mi2 (1,900-km2) watershed, it is situated at the lowest point within the San Jacinto River watershed of , at the terminus of the San Jacinto River. It is the terminal lake of a partially closed basin called the San Jacinto Basin. Lake water levels are healthy at an average of above sea level with a volume of which often fluctuates, although much has been done recently to prevent the lake from drying up, f ...

Topographic Map
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and artificial features. A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection, coordinate system, ellipsoid and geodetic datum. Official topographic maps also adopt a national grid referencing system. Natural Resources Canada provides this description of topographic maps: Other authors define topographic maps by contrasting them with ...

Temescal Mountains
The Temescal Mountains, also known as the Sierra Temescal ( Spanish for "sweat lodge range"), are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block. The Santa Ana Mountains lie to the west, the Elsinore Mountains to the south and the Perris Valley and Lakeview Mountains to the east. History The Temescal Mountains were originally named by the Spanish as Sierra Temescal (perhaps from the nearby Rancho Temescal), a name which appears on the Rail Road Route survey map made by the U. S. Army Pacific Railroad Surveys in 1854–55. The Temescal Mountains are one of the northernmost of Peninsular Ranges of California, running from the south side of the Santa Anna River, southeast nearly parallel with the ...
