Lake Hodges
Lake Hodges is a lake and reservoir located within the city limits of San Diego, California. It is about north of Downtown San Diego, just north of the Rancho Bernardo community, and just south of the city's border with Escondido. When full, the reservoir has , a maximum water depth of , and of shoreline. Lake Hodges has a total capacity of 30,251 acre-feet of water. Lake Hodges is owned by the city of San Diego, supplies water to thSan Dieguito Water DistrictanSanta Fe Irrigation District and its mailing city address is Escondido. Water level elevation in the lake is maintained at a maximum of above sea level, lower than the dam's maximum of spillway to ensure safe operations. The lake level can fluctuate significantly, depending upon the amount of runoff received from the San Dieguito River drainage basin. Interstate 15 crosses Lake Hodges via the Lake Hodges Bridge. Approximately west of the I-15 freeway bridge is a bicycle/pedestrian bridge which opened on May 15, 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypolimnetic Aeration
Via deep water aeration or hypolimnetic aeration, the oxygen demand of deep water is provided by oxygen from the atmosphere without destroying the lake’s natural stratification. Thus the deep water becomes aerobic, the dissolving of phosphates is reduced significantly and the production of ammonia by sediments improves. Scientific evidence shows that it is possible to keep the deep water clean through this process all year round via technical ventilation measures and thereby to recover the natural balance of lakes effectively.Steinberg, C., Bernhardt, H.: Handbuch Angewandte Limnologie – 14. Erg.Lfg. 4/0 Verlag: Hüthig Jehle Rehm, 2002, . Eutrophication In stratified, eutrophic lakes an oxygen deficit in deep water is created during summer stagnation. As a result of elevated nutrient inputs, the trophic level of many lakes increases continuously. Elevated phosphorus concentrations may lead to stronger algae growth and a corresponding increase in oxygen consumption in the d ...

Reservoirs In California
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. 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 re ...

List Of Lakes In California
There are more than 3,000 named lakes, reservoirs, and dry lakes in the U.S. state of California. Largest lakes In terms of area covered, the largest lake in California is the Salton Sea, a lake formed in 1905 which is now saline. It occupies in the southeast corner of the state, but because it is shallow it only holds about of water. Tulare Lake in the San Joaquin Valley was larger, at approximately , until it was drained during the later years of the nineteenth century. In terms of volume, the largest lake on the list is Lake Tahoe, located on the California–Nevada border. It holds roughly of water. It is also the largest freshwater lake by area, at , and the deepest lake, with a maximum depth of . Among freshwater lakes entirely contained within the state, the largest by area is Clear Lake, which covers . Many of California's large lakes are actually reservoirs: artificial bodies of fresh water. In terms of both area and volume, the largest of these is Lake S ...

Clark's Grebe
Clark's grebe (''Aechmophorus clarkii'') is a North American waterbird species in the grebe family. Until the 1980s, it was thought to be a pale Polymorphism (biology), morph of the western grebe, which it resembles in size, range, and behavior. Intermediates between the two species are known. This species nests on large inland lakes in western North America and bird migration, migrates to the Pacific coast over the winter. It maintains local populations year-round in California, Nevada, and Arizona (the Lower Colorado River Valley), as well as in central Mexico. It feeds by diving for insects, polychaete worms, crustaceans, and salamanders. It performs the same elaborate courtship display as the western grebe. Etymology and common names The "Clark" of its common name—and its specific epithet ''clarkii''—honors John Henry Clark, a 19th-century American surveyor who was also a naturalist and collector. The genus name ''Aechmophorus'' comes from the Ancient Greek words αἰ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Grebe
The western grebe (''Aechmophorus occidentalis'') is a species in the grebe family of water birds. Folk names include "dabchick", "swan grebe" and "swan-necked grebe". Western grebe fossils from the Late Pleistocene of southwest North America were described as a distinct species, but later ranked as a paleosubspecies ''Aechmophorus occidentalis lucasi''. More recent study found them to fall within the variation now known to exist in today's birds. Description The western grebe is the largest North American grebe. It is long, weighs and measures across the wings.''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), .Burnie D and Wilson DE (Eds.), ''Animal: The Definitive Visual Guide to the World's Wildlife''. DK Adult (2005), It is black-and-white, with a long, slender, swan-like neck and red eyes. It is easily confused with Clark's grebe, which shares similar features, body size, behavior and habitat, and Hybrid (biology), hybrids are known ...

Cactus Wren
The cactus wren (''Campylorhynchus brunneicapillus'') is a species of wren endemic to the deserts of the southwestern United States and northern and central Mexico. It is the state bird of Arizona, and the largest wren in the United States. Its plumage is brown, with black and white spots as markings. It has a distinctive white eyebrow that sweeps to the nape of the neck. The chest is white, whereas the underparts are cinnamon-buff colored. Both sexes appear similar. The tail, as well as flight feathers, are barred in black and white. Their song is a loud raspy chirrup; akin in the description of some ornithologists to the sound of a car engine that will not start. It is well-adapted to its native desert environment, and the birds can meet their water needs from their diet which consists chiefly of insects, but also of some plant matter. The cactus wren is a poor flier and generally forages for food on the ground. Ornithologists generally recognize seven subspecies, with th ...

California Gnatcatcher
The California gnatcatcher (''Polioptila californica'') is a small long insectivorous bird which frequents dense coastal sage scrub growth. This species was recently split from the similar black-tailed gnatcatcher of the Sonoran and Chihuahuan deserts. This bird is often solitary, but joins with other birds in winter flocks. Description The male California gnatcatcher is dusky gray overall, distinguished only by its black crown and thin black beak. It has a long, thin black tail with narrow white tips and edges on the underside of the tail feathers. However, the male loses its plumage colors by winter and obtains a plumage color similar to the females. The female is similar to the male, but with a blue-gray instead of a black crown. In its range from coastal Southern California south through Baja California and Baja California Sur, this inconspicuous non- migratory resident is most often seen flitting hastily into undergrowth, or heard giving its call, which sounds like a kitten ...

Least Bell's Vireo
Bell's vireo (''Vireo bellii'') is a songbird that migrates between a breeding range in Western North America and a winter range in Central America. It is dull olive-gray above and whitish below. It has a faint white eye ring and faint wing bars. This bird was named by Audubon for John Graham Bell, who accompanied him on his trip up the Missouri River in the 1840s. The least Bell's vireo (''Vireo bellii pusillus'') is an endangered subspecies in Southern California. Consideration of Bell's vireo has been a factor in several land development projects, to protect least Bell's vireo habitat. The decline of the least Bell's vireo is mostly due to a loss of riparian habitat. Description Measurements: * Length: 4.5-4.9 in (11.5-12.5 cm) * Weight: 0.3-0.3 oz (7.4-9.8 g) * Wingspan: 6.7-7.5 in (17-19 cm) Behavior and ecology Bell's vireos often use dense shrubbery including willows (''Salix spp.''), mulefat (''Baccharis glutinosa''), California wild rose (''Rosa californica''), m ...
