Blackwater River (Contoocook River)
The Blackwater River is a river located in central New Hampshire in the United States. It is a tributary of the Contoocook River, part of the Merrimack River watershed. The Blackwater River is formed at Cilleyville, a village in the western part of the town of Andover, by the junction of two branch streams. Cascade Brook, the western branch, begins at Cascade Marsh in the northeast part of Sutton and flows northeast to Wilmot Flat, where it is joined by the outlet of Pleasant Lake of New London before continuing east to Cilleyville. Frazier Brook, the northern stream branch, rises just south of Danbury village and flows south parallel to Route 4, passing South Danbury, flowing through Eagle Pond in Wilmot and then through Bog Pond below West Andover, joining Cascade Brook just south of the outlet of Bog Pond. Kimpton Brook (formerly known as Quickwater Brook), flowing easterly through the village of Wilmot Center, is the primary tributary of Eagle Pond. From its start at Cille ...

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...

Merrimack River
The Merrimack River (or Merrimac River, an occasional earlier spelling) is a river in the northeastern United States. It rises at the confluence of the Pemigewasset and Winnipesaukee rivers in Franklin, New Hampshire, flows southward into Massachusetts, and then flows northeast until it empties into the Gulf of Maine at Newburyport. From Pawtucket Falls in Lowell, Massachusetts, onward, the Massachusetts–New Hampshire border is roughly calculated as the line three miles north of the river. The Merrimack is an important regional focus in both New Hampshire and Massachusetts. The central-southern part of New Hampshire and most of northeast Massachusetts is known as the Merrimack Valley. Several U.S. naval ships have been named and USS ''Merrimac'' in honor of this river. The river is perhaps best known for the early American literary classic ''A Week on the Concord and Merrimack Rivers'' by Henry David Thoreau.

Made up of roughly 3,500 employees in six districts and a Division headquarters, the North Atlantic Division is a major subordinate command and serves to integrate the capabilities of its six districts. They plan, design and build for the Army and Air Force in the northeastern states and Europe, develop and manage water resources, and protect and restore the environment. They also work for other international, federal, state and local customers and agencies. Division headquarters are at 302 John Warren Avenue in Fort Hamilton in Brooklyn, New York. The division is responsible for six subordinate engineer districts with headquarters in Concord, Massachusetts, New York City, Philadelphia, Baltimore, Norfolk and Wiesbaden, Germany.

Reservoirs In New Hampshire
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. 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 re ...

Dams Completed In 1941
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, tap water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.
