Painted Rock Reservoir
The Painted Rock Dam is an earthfill embankment dam located west of Gila Bend, Arizona. It is primarily used for flood control purposes. Description The Painted Rock Dam was constructed during a 3-year period from 1957–1960 by the United States Army Corps of Engineers to help control seasonal floods on the lower reaches of the Gila River. The river had no significant impediments between the Colorado River and the Coolidge Dam hundreds of miles upstream. In this stretch the river receives several tributaries, including the Hassayampa, Agua Fria rivers, and most importantly the Salt River and its major tributary, the Verde River. Due to a relatively large watershed of , more than half of which is unregulated, the flood threat to small farming communities downstream on the Gila River is large, and seasonal flooding of these areas prior to the construction of the dam was significant. The area surrounding the dam has also hosted a number of historical events. The Butterfield ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gila River
The Gila River (; O'odham ima Keli Akimel or simply Akimel, Quechan: Haa Siʼil, Maricopa language: Xiil) is a tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly that lies mainly within the U.S., but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century. During the 20th century, human development of the Gila River watershed prompted the construction of large diversion and flood control structures on the river and its tributaries, and consequently the Gila now contributes only a small fraction of its historic flow to the Colorado. The historic natural discharge of the river is around , and is now only . These engin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Juan Bautista De Anza
Juan Bautista de Anza Bezerra Nieto (July 6 or 7, 1736 – December 19, 1788) was an expeditionary leader, military officer, and politician primarily in California and New Mexico under the Spanish Empire. He is credited as one of the founding fathers of Spanish California and served as an official within New Spain as Governor of the Province of New Mexico. Early life Juan Bautista de Anza Bezerra Nieto was born in Fronteras, New Navarre, New Spain (today Sonora, Mexico) in 1736 (near Arizpe), most probably at Cuquiarachi, Sonora, but possibly at the Presidio of Fronteras. His family was a part of the military leadership in Nueva España, as his father and maternal grandfather, Captain Antonio Bezerra Nieto, had both served Spain, their families living on the frontier of Nueva Navarre. He was the son of Juan Bautista de Anza I. It is traditionally thought that he may have been educated at the College of San Ildefonso in Mexico City, and later at the military academy there. In ...

Reservoirs In Maricopa County, Arizona
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 res ...

Dams In Arizona
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ...

Gillespie Dam Bridge
The Gillespie Dam Bridge (sometimes referred to as the Gillespie Dam Highway Bridge) is a through truss bridge spanning the Gila River in Maricopa County, Arizona, Maricopa County, in the U.S. state of Arizona. The bridge was constructed to Bypass (road), bypass a concrete apron through the river in front of the Gillespie Dam, which was often closed due to flooding. Construction of the bridge started in 1925 and completed in 1927. From its opening until 1956, the bridge was part of U.S. Route 80 in Arizona, U.S. Route 80 (US 80), a transcontinental highway between San Diego, California and Tybee Island, Georgia. The bridge was restored in 2012 by Maricopa County for the Arizona Centennial and now includes an educational interpretive center for visitors. The bridge became part of Historic US 80 in 2018. History The Ocean-to-Ocean Highway was established in 1911 after delegates from California, Arizona and New Mexico met in Phoenix. The purpose of the new route was to est ...

Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or a ...

Theodore Roosevelt Lake
Theodore Roosevelt Lake (usually called Roosevelt Lake, sometimes Lake Roosevelt) is a large reservoir formed by Theodore Roosevelt Dam on the Salt River (Arizona), Salt River in Arizona as part of the Salt River Project (SRP). Located roughly 80 miles (130 km) northeast of Phoenix, Arizona, Phoenix in the Salt River Valley, Theodore Roosevelt is the largest lake or reservoir located entirely within the state of Arizona (Lake Mead and Lake Powell are larger but are both located partially within the bordering states of Nevada and Utah respectively). The reservoir and the masonry dam that created it, Roosevelt Dam, were both named after U.S. President Theodore Roosevelt who dedicated the dam himself in March 1911. Roosevelt Lake is a popular recreation destination within the Tonto National Forest; the facilities located at this lake are managed by that authority. Roosevelt Lake is the oldest of the six reservoirs constructed and operated by the Salt River Project. It also has ...

Evaporation
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it will escape and enter the surrounding air as a gas. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid. The evaporation will continue until an equilibrium is reached when the evaporation of the liquid is equal to its condensation. In an enclosed environment, a liquid will evaporate until the surrounding air is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
