River Mile
A river mile is a measure of distance in miles along a river from its mouth. River mile numbers begin at zero and increase further upstream. The corresponding metric unit using kilometers is the river kilometer. They are analogous to vehicle roadway mile markers, except that river miles are rarely marked on the physical river; instead they are marked on navigation charts, and topographic maps. Riverfront properties are sometimes partially legally described by their river mile. The river mile is not the same as the length of the river, rather it is a means of locating any feature along the river relative to its distance from the mouth, when measured along the course (or navigable channel) of the river. River mile zero may not be exactly at the mouth. For example, the Willamette River (which discharges into the Columbia River) has its river mile zero at the edge of the navigable channel in the Columbia, some beyond the mouth. Also, the river mile zero for the Lower Mississipp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allegheny Islands State Park
Allegheny Islands State Park is a Pennsylvania state park in Harmar Township, Allegheny County, Pennsylvania in the United States. The undeveloped park is composed of three alluvial islands located in the middle of the Allegheny River northeast of Pittsburgh. The islands are just north of the boroughs of Oakmont and Plum, and southwest of Cheswick. ''Note: shows Allegheny River and its islands'' Bridges for the Pennsylvania Turnpike ( Interstate 76) and the Bessemer and Lake Erie Railroad Branch of the Canadian National Railway cross the Allegheny River at the middle island. Islands The park land on the islands has a total area of , with two islands downstream of the Allegheny River Lock and Dam Three (officially named the ''C. W. Bill Young Lock and Dam''), and the other island upstream. Twelve Mile Island is the farthest downstream (west) and has a number of houses and buildings on the western four-fifths of the island (the park land is the eastern end). The remainin ...

Rivers
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, " burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, ...

Caballo Dam
Caballo Dam is an earthen dam on the Rio Grande about downstream from Truth or Consequences, New Mexico, United States. In conjunction with Elephant Butte Dam, which lies about upstream, it regulates the discharge of the river in the lower Rio Grande Valley of New Mexico. Caballo serves as an afterbay for the Elephant Butte Reservoir, i.e. it stores water released from Elephant Butte for hydroelectricity generation purposes and discharges it in the dry season to provide for irrigation agriculture downstream. The dam is an important part of the Rio Grande Project. A secondary purpose of the dam was to compensate for lost capacity in Elephant Butte Lake due to sedimentation. Caballo Dam is high and stands above the Rio Grande. It is long and contains of material. The elevation of the crest is and the average elevation of its reservoir, Caballo Lake, is . The dam has two water outlets; the outlet works have a capacity of , and the main spillway has a capacity of . Caball ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embudo, New Mexico
Embudo (also Embudo Station) is an unincorporated community in Rio Arriba County, New Mexico, United States. It is on New Mexico State Road 68. The Embudo Station is located south of the intersection of New Mexico State Road 75, near where the Embudo Creek (Rio Embudo) flows into the Rio Grande. Etymology The name "Embudo", meaning "funnel" in Spanish, was given to the area by early Spanish settlers because the spot where the Rio Embudo flowed between two distinctive cone shaped hills reminded them of a funnel. Embudo was founded in 1881 when the Denver and Rio Grande Western Railroad opened a station (depot) there on its Chili Line. The station was named after the village San Antonio de Embudo, located two miles up the Embudo Creek, and until 1902 the communities shared a post office and were known jointly as Embudo. In 1900, anticipating a separate post office in the village, San Antonio de Embudo changed its name to Dixon after the Presbyterian missionary Dixon, who estab ...

Saint Lawrence Seaway
The St. Lawrence Seaway (french: la Voie Maritime du Saint-Laurent) is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes. The St. Lawrence River portion of the seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United S ...

Lake Erie
Lake Erie ( "eerie") is the fourth largest lake by surface area of the five Great Lakes in North America and the eleventh-largest globally. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Situated on the International Boundary between Canada and the United States, Lake Erie's northern shore is the Canadian province of Ontario, specifically the Ontario Peninsula, with the U.S. states of Michigan, Ohio, Pennsylvania, and New York on its western, southern, and eastern shores. These jurisdictions divide the surface area of the lake with water boundaries. The largest city on the lake is Cleveland, anchoring the third largest U.S. metro area in the Great Lakes region, after Greater Chicago and Metro Detroit. Other major cities along the lake shore include Buffalo, New York; Erie, Pennsylvania; and Toledo, Ohio. Situated below Lake Hur ...

Ohio River
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although i ...

Sewage Treatment
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
