Triadelphia Reservoir
Triadelphia Reservoir is a reservoir located on the Patuxent River, in Howard County and Montgomery County, Maryland near the town of Brookeville. The reservoir was created in 1943 by the construction of the Brighton Dam on the Patuxent. History The river valley was once occupied by prehistoric Native American settlements surveyed in the 1980s when the modern dam was drained for maintenance. The reservoir is located on a land grant surveyed by Benjamin Gaither in 1725. It was named after the town of Triadelphia which was founded in 1809 by three Quaker brothers-in-law. Isaac Briggs, Thomas Moore, and Revolutionary veteran and silversmith Caleb Bentley built a small town on 276 acres of land with nine houses, sawmill, general store, grist mill, and a mill race. The property was expanded to 515 acres containing the land grant "Benjamin's Lot" and "What's Left". The Triadelphia Cotton Factory (Montgomery Manufacturing Company) managed by Allen Bowie Davis operated 196 spindles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lakes Of Howard County, Maryland
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Reservoirs In Maryland
A reservoir (; ) is an enlarged lake behind a dam, usually built to 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 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 creeks, rivers or rainwater that runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rocky Gorge Reservoir
Rocky Gorge Reservoir is located on the Patuxent River in Howard, Montgomery, and Prince George's counties in Maryland, between Laurel and Burtonsville. The reservoir was created in 1952 by the construction of the T. Howard Duckett Dam on the Patuxent. The dam is visible from Interstate 95 near milemarker 34. Because of its close association with a dam by the name, the reservoir is sometimes called the T. Howard Duckett Reservoir. It has a surface area of . The reservoir is maintained as a drinking water source by the Washington Suburban Sanitary Commission (WSSC). WSSC provides recreational facilities to the public on portions of the Rocky Gorge property, including hiking, picnicking, fishing, boating, horseback riding, and hunting. Local fish species include pike and largemouth bass. Namesake T.

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tainter Gate
The Tainter gate is a type of radial arm floodgate used in dams and canal locks to control water flow. It is named for its inventor, the Wisconsin structural engineer Jeremiah Burnham Tainter. Tainter, an employee of the lumber firm Knapp, Stout and Co., invented the gate in 1886 for use on the company's dam that forms Lake Menomin in the United States. Description A side view of a Tainter gate resembles a slice of pie with the curved part of the piece facing the source or upper pool of water and the tip pointing toward the destination or lower pool. The curved face or skinplate of the gate takes the form of a wedge section of cylinder. The straight sides of the pie shape, the trunnion arms, extend back from each end of the cylinder section and meet at a trunnion which serves as a pivot point when the gate rotates. Principle Pressure forces on a submerged body act perpendicular to the body's surface. The design of the Tainter gate results in every pressure force acting t ...

Drinking Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Allen Bowie Davis
Allen Bowie Davis (1809–1889) was an American businessman. Davis was born in Montgomery County Maryland to Thomas Davis (1769–1833) and Elizabeth Bowie (1772–1840). His father participated in the Whiskey Rebellion and was the president of the Board of Trustees of the Brookeville Academy, a position that Allen would take later at the age of 24. Davis took over the estate farm Greenwood at 16 and would write educational books on agriculture. By 1850 he would own 27 slaves to maintain four separate farms. In 1840 he would be appointed to the board of public works for Maryland. This in turn led to him becoming the director and trustee of the Chesapeake and Ohio Canal during the final 50 miles of construction. In 1846, Davis imported 1,400 tons of Guano for $100,000 to redistribute to farmers without markup. Davis also returned the Triadelphia Cotton Company to profitability. In 1850 he would represent at the state constitutional convention, helping form the Maryland Agricultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
