Little Seneca Creek
Little Seneca Creek is an U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed August 15, 2011 stream in Montgomery County, Maryland, roughly northwest of Washington, D.C. Geography The creek drains portions of Clarksburg, Germantown, and Boyds. It rises south of Damascus and flows southward about to Little Seneca Lake, a reservoir created by construction of a dam on the creek. The reservoir empties to the lower portion of the creek, which flows south about to Seneca Creek, which drains to the Potomac River and the Chesapeake Bay. A portion of the creek below the lake is a cold water stream that supports wild rainbow and brown trout populations. The creek and reservoir are a drinking water source as part of the Little Seneca system, an emergency water supply for the metropolitan Washington, D.C. area. Water quality issues In 1994, the Montgomery County Council anticipated population growth in the Little Seneca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural). It usually includes issues surrounding policy and regulation, service provision and standardization. The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). Almost all service providers in the world charge tariffs to recover part of their costs. Water supply is a separat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Montgomery County, Maryland
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tenmile Creek (Maryland)
Tenmile Creek is a tributary stream of Little Seneca Creek in Montgomery County, Maryland. Course The headwaters of the stream originate in Thompsons Corner area of the county, about northwest of Clarksburg, and the creek flows south for about , to Little Seneca Lake, a reservoir built on Little Seneca Creek. Little Seneca Creek drains to the Potomac River and the Chesapeake Bay. Water quality and land use issue The Tenmile Creek watershed is described as one of the highest-quality stream systems in Montgomery County, according to government studies. It is a drinking water source as part of the Little Seneca system, an emergency water supply for the metropolitan Washington, D.C. area. The creek's main stem is extensively forested and the watershed contains some agricultural land. However, the basin is bisected by an interstate highway, I-270, and in the late 1980s the county began planning for additional land development in the Clarksburg area. In 1994 the county governme ...

Low-impact Development (Canada/US)
Low-impact development (LID) is a term used in Canada and the United States to describe a land use planning, land planning and environmental engineering, engineering design approach to manage stormwater surface runoff, runoff as part of green infrastructure. LID emphasizes water conservation, conservation and use of on-site natural features to protect water quality. This approach implements engineered small-scale hydrologic controls to replicate the pre-development Surface-water hydrology, hydrologic regime of Drainage basin, watersheds through infiltration (hydrology), infiltrating, filtration, filtering, storing, evaporation, evaporating, and detaining runoff close to its source. Green infrastructure investments are one approach that often yields multiple benefits and builds city resilience. Broadly equivalent terms used elsewhere include Sustainable drainage systems (SuDS) in the United Kingdom (where LID has Low-impact development (UK), a different meaning), water-sensitive ...

Stormwater Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to '' channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made cont ...

Bioindicator
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative information on the quality of the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional information about the amount and intensity of the exposure. A biological indicator is also the name gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stormwater
Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies (wetlands, lakes and oceans) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots. In developed environments, such as cities, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff ( flooding) and the other related to potential contaminants the water is carrying (water pollution). In addition to the pollutants carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and often determines supply options. Impacts on public health Over time, there has been increasing recognition of the importance of drinking water quality and its impact on public health. This has led to increasing protection and management of water quality.
