Max. depth 80 feet (24 m) Lake Anna is one of the largest freshwater inland reservoirs in Virginia , covering an area of 13,000 acres (53 km 2 ), and located 72 miles (116 km) south of Washington, D.C. , in Louisa and Spotsylvania counties (and partially in Orange County at the northern tip).
Depth in a well. In the oil and gas industry, depth in a well is the distance along a well between a point of interest and a reference point or surface. It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, depth is a vertical coordinate ...
The Permian Basin is a large sedimentary basin in the southwestern part of the United States. It is the highest producing oil field in the United States, producing an average of 4.2 million barrels of crude oil per day in 2019. This sedimentary basin is located in western Texas and southeastern New Mexico. It is named after the Permian geologic ...
Overall the average lake elevation is 657.5 feet (200.4 m). [3] As of the first of October 2010, the lake had returned to just over 654 feet (199 m). [ 9 ] This rebound in lake level is due to releases from the lake being suspended for a month ending April 10, 2009, in an effort to return Lake Hartwell to normal elevations.
The frost line —also known as frost depth or freezing depth —is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt ...
Cheney Reservoir. 1 Shore length is not a well-defined measure. Cheney Reservoir is a reservoir on the North Fork Ninnescah River in Reno, Kingman, and Sedgwick counties of Kansas in the United States. [5] Built and managed by the U.S. Bureau of Reclamation for local water supply, it is also used for flood control and recreation.
Barnett Shale - stratigraphy. The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks dating from the Mississippian period (354–323 million years ago) in Texas. The formation underlies the city of Fort Worth and underlies 5,000 mi 2 (13,000 km 2) and at least 17 counties.
Lake Erie (42.2° N, 81.2W) has a mean elevation of 571 feet (174 m) [8] above sea level. It has a surface area of 9,990 square miles (25,874 km 2) [7] with a length of 241 statute miles (388 km; 209 nmi) [7] and breadth of 57 statute miles (92 km; 50 nmi) [7] at its widest points. It is the shallowest of the Great Lakes with an average depth ...
