Lake Braddock
Lake Braddock is a reservoir in the community of Burke in Fairfax County, Virginia, United States. Lake Braddock is created by an impoundment on a tributary stream of Pohick Creek, itself a tributary of the Potomac River. In 1969, the Fairfax County Board of Supervisors and the Northern Virginia Soil District signed contracts which allowed the construction of the dam impounding the tributary of the Pohick creek in Burke. The $138,500 cost of the dam, intended as the first of eight to control soil erosion and flooding in the Pohick watershed, was split between the U.S. Department of Agriculture and the Yeonas Development Corporation, the latter of which intended to build a 1000-unit development on the surrounding . The ultimate cost of the dam creating the lake was $93,000 to the U.S. Government and $104,000 to Yeonas. The fact that the lake included no public recreation facilities despite being financed with public money was the subject of controversy, and led to the amendment ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. 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 reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Pohick Creek
Pohick Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 tributary stream of the Potomac River in Fairfax County in the U.S. state of Virginia. It takes its name from the Pohick Native American tribe once prevalent in the area. Pohick Creek forms in the vicinity of Burke and flows southeast past the western edge of Fort Belvoir to empty into the tidal Pohick Bay, which itself empties, along with Accotink Bay, into Gunston Cove, an embayment of the tidal Potomac River. Pohick Creek is a popular stream for whitewater kayaking, rafting, and paddling, providing Class II and III rapids along a stretch between Hooes Road (Virginia Secondary Route 636) and the Richmond Highway ( U.S. Route 1) at Lorton. Several tributaries of the Pohick Creek are impounded by dams constructed under the Watershed Protection and Flood Prevention Act to prevent soil erosion and flooding. Originally eight dams w ...

Soil Erosion
Soil erosion is the denudation or wearing away of the Topsoil, upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, Atmosphere of Earth, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, Aeolian erosion, wind (aeolian) erosion, Zoogenic erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from Agricultural land, farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Exc ...

Watershed Protection And Flood Prevention Act Of 1954
The United States Watershed Protection and Flood Prevention Act of 1954 () is a United States statute. It has been amended several times. Under this Act, the Soil Conservation Service at the Department of Agriculture provides planning assistance and construction funding for projects constructed by local sponsors, often in the form of flood control districts. Restrictions on projects include: the size of the watershed must be 250,000 acres (1011 km²) or less; no single structure may provide more than of flood water retention; no single dam may provide more than of total capacity; and projects with costs greater than $5 million or with structures with total capacities greater than must be approved by Congress. The original 1954 statute sought cooperation between the federal government and states and localities to prevent flood damage. The Secretary of Agriculture was authorized to construct flood protection measures below a certain volume limit. Such initiatives were to be ...

Chesapeake Bay Watershed
The Chesapeake Bay ( ) is the largest estuary in the United States. The bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware. The mouth of the bay at its southern point is located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the bay's drainage basin, which covers parts of six states ( New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia) and all of Washington, D.C. The bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is wide at its narrowest (between Kent Co ...

Protected Areas Of Fairfax County, Virginia
Protection is any measure taken to guard something against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...
