Spavinaw Creek
Spavinaw Creek is a stream that begins in Arkansas and flows west into Oklahoma. The mouth is at located at Lake Hudson. The creek drains 400 square miles of the Ozark Mountain foothills and farm land. Two lakes, Lake Spavinaw and Lake Eucha, were impounded to create water supplies for the city of Tulsa approximately 55 miles away. Description The actual source begins as a drainage basin and a mostly dry to intermittent brook in northwest Arkansas, flowing west into Oklahoma, picking up intermittent drainage, run-off, and tributaries such as Brush Creek, Dry Creek, Columbia Hollow Creek, Rattlesnake Creek, Cloud Creek, Cherokee Creek, Hog Eye Creek, Spring Branch, and Wolf Creek, that is the Decatur waste discharge point, and others. The creek drains 400 square miles of Ozark Mountain foothills and is a tributary of Grand River. Dams The first dam was built in 1923 creating Lake Spavinaw as part of the Spavinaw Water Project. Much of the town of Spavinaw had to be relocate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CAFO
In animal husbandry, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year. An animal unit is the equivalent of 1,000 pounds of "live" animal weight. A thousand animal units equates to 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than , 10,000 pigs weighing under 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg laying hens or pullets. CAFOs are governed by regulations that restrict how much waste can be distributed and the quality of the waste materials. As of 2012 there were around 212,000 AFOs in the United States, 19,496 of which were CAFOs. Livestock production has become increasingly dominated by CAFOs in the United States and other parts of the world. Most poultry was raised in CAFOs starting in the 1950s, and most cattle and pigs by the 1970s and 1980s. By the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterococcus
''Enterococcus'' is a large genus of lactic acid bacteria of the phylum Bacillota. Enterococci are gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. Two species are common commensal organisms in the intestines of humans: '' E. faecalis'' (90–95%) and '' E. faecium'' (5–10%). Rare clusters of infections occur with other species, including ''E. casseliflavus'', '' E. gallinarum'', and ''E. raffinosus''. Physiology and classification Enterococci are facultative anaerobic organisms, i.e., they are capable of cellular respiration in both oxygen-rich and oxygen-poor environments. Though they are not capable of forming spores, enterococci are tolerant of a wide range of environmental conditions: extreme temperature (10–45 °C), pH (4.6–9.9), and high sodium chloride concentrations. Enterococci typically exhibit gamma-hemolysis on sheep's blood agar. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spavinaw Water Project
The Spavinaw Water Project was established to provide fresh water for Tulsa, Oklahoma from a site on Spavinaw Creek near the town of Spavinaw in Mayes County, Oklahoma. Planning and financing began in 1919, The project scope included site selection, designing and constructing a dam to impound the creek, a 55-mile long pipeline to carry water to a reservoir near Tulsa, where it would be treated and pumped to a network of customers. Groundbreaking occurred in October, 1922. The dam and pipeline were both completed in 1924, and the new Tulsa water treating plant was completed in 1929. At that time, this was the longest gravity-flow water pipeline operational in the United States. Background According to an article written by Dr. Fred S. Clinton, a pioneer Tulsa physician, there were a number of freshwater springs in the immediate vicinity. However, it soon became apparent that these could not support the needs of the rapidly expanding population. The city built a pumping plant in 1 ...

Ozark Mountain
The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, Oklahoma and the extreme southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri. There are two mountain ranges in the Ozarks: the Boston Mountains of Arkansas and the St. Francois Mountains of Missouri. Buffalo Lookout, the highest point in the Ozarks, is located in the Boston Mountains. Geologically, the area is a broad dome with the exposed core in the ancient St. Francois Mountains. The Ozarks cover nearly , making it the most extensive highland region between the Appalachians and Rockies. Together with the Ouachita Mountains, the area is known as the U.S. Interior Highlands. The Salem Plateau, named after Salem, Missouri, makes up the largest geologic area of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...

River Source
The headwaters of a river or stream is the farthest place in that river or stream from its estuary or downstream confluence with another river, as measured along the course of the river. It is also known as a river's source. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream". As an example of the second definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above (along with virtually all other geographic authorities and publications) in using the combined Missouri—lower Mississippi length figure in lists of lengths of rivers around the world. Most rivers have numerous tributaries and change names often; it is customary to regard the longest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
