Morelos Dam
After a 1944 United States Mexico Treaty the Morelos Dam was built in 1950 across the Colorado River. It is located about below the junction of the California border and the Colorado River between the town of Los Algodones, Baja California, in northwestern Mexico and Yuma County, Arizona in the southwestern United States. The eastern half of the dam lies inside United States territory; but Mexico is responsible for all maintenance. The dam allows Mexico to divert its allotted water from the Colorado River to highly developed crop lands in the Mexicali, Mexico Valley. The Morelos Dam is the final dam on the Colorado River. It is run by the International Boundary and Water Commission (IBWC). On March 23, 2014, an eight-week flood was begun with the opening of a gate at Morelos Dam. The goal is to rejuvenate a desert riparian habitat which naturalist Aldo Leopold explored in 1922 and described as "awesome jungles" and "lovely groves" in his memoir ''A Sand County Almanac ''A Sand ...

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

A Sand County Almanac
''A Sand County Almanac: And Sketches Here and There'' is a 1949 non-fiction book by American ecologist, forester, and environmentalist Aldo Leopold. Describing the land around the author's home in Sauk County, Wisconsin, the collection of essays advocate Leopold's idea of a "land ethic", or a responsible relationship existing between people and the land they inhabit. Edited and published by his son, Luna, a year after Leopold's death, the book is considered a landmark in the American conservation movement. The book has had over two million copies printed and has been translated into at least fourteen languages. It has informed and changed the environmental movement and stimulated a widespread interest in ecology as a science. Overview ''A Sand County Almanac'' is a combination of natural history, scene painting with words, and philosophy. It is perhaps best known for the following quote, which defines his land ethic: "A thing is right when it tends to preserve the integrity, ...

Buildings And Structures In Yuma County, Arizona
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams Of The Lower Colorado River Valley
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.

Dams On The Colorado River
This is a list of dams on the Colorado River system of the southwestern United States and northwestern Mexico. The Colorado runs from the Rocky Mountains to the Gulf of California, draining parts of seven U.S. states and two Mexican states. The river system is one of the most heavily developed in the world, with fifteen dams on the main stem of the Colorado and hundreds more on tributaries. Collectively, dams in the Colorado River basin can hold four to five times the river's annual flow, generating hydroelectricity and supplying irrigation and municipal water for over 35 million people. Dams on tributaries are listed if they are taller than , store more than , or are otherwise historically notable. Tributary dams are organized into two lists; those in the Upper Basin, defined as the half of the Colorado River basin above Lee's Ferry, Arizona, and the Lower Basin. The Upper Basin include such tributary systems as the Green, Gunnison and San Juan. Tributaries in the Lower Basin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desert Riparian
Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of valleys, canyons, and other watercourses that have water at or near the surface most of the year.Pam MacKay, Mojave Desert Wildflowers, 2nd Ed., p. 20-21 The visual character is of large, lush, perennial green trees surrounded by dry desert vegetation and soil coloration. The area may be in a patch surrounding a spring such as an oasis, or in a strand following the course of water flow, such as a bosque. The soil in this biome is typically moist and ranges from rocky and sandy to silty alluvium. This biome has seasonal variation, with hot, dry summers and cool, moist winters. Precipitation mostly occurs during the winter, and ranges from 8 to 25 cm each year. It is contrasted with the desert dry wash vegetation type, in which water at or near the surface is lacking most of the year, such as arroyos. Over 80% of known desert wildlife species use desert riparian areas. Comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Boundary And Water Commission
The International Boundary and Water Commission ( es, links=no, Comisión Internacional de Límites y Aguas) is an international body created by the United States and Mexico in 1889 to apply the rules for determining the location of their international boundary when meandering rivers transferred tracts of land from one bank to the other, as established under the Convention of November 12, 1884. The organization was created as the International Boundary Commission by the Convention of 1889 between the United States and Mexico. It was given its present name under the 1944 "Treaty relating to the Utilization of Waters of the Colorado and Tijuana Rivers and of the Rio Grande". Under these agreements, the IBWC has a U.S. section and a Mexican section, headquartered in the adjoining cities of El Paso, Texas, and Ciudad Juárez, Chihuahua. The U.S. section is administered by the Department of State, and the Mexican part by the Secretariat of Foreign Relations. Administration So ...
