Hartwick Lake
Delhi Dam, also known as Hartwick Dam, is an embankment dam on the Maquoketa River southwest of Delhi, Iowa that created Lake Delhi. The dam was over-topped and subsequently failed on July 24, 2010 after a period of heavy rain. It was rebuilt in 2016. The dam and lake are part of the Turtle Creek Recreation Area, and is owned by a local community group. History The dam was built between 1922 and 1929 by the Interstate Power Company for hydroelectric power production, but its generators ceased operating in 1973 shortly before the Lake Delhi Recreation Association took ownership. Since then, it has been used for recreation. Several floods in 2008 caused an estimated $500,000 in damages to the dam and its floodgates. In October 2008, the Association signed a partnership with Modern Hydro to have the power plant's turbines refurbished and recommissioned. The new power plant was to have two turbine generators with a 1.5 MW capacity able to produce 3 GWh of electricity annually fo ...

Buildings And Structures In Delaware County, Iowa
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disasters In Iowa
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either " natural disasters" caused by natural hazards or "human-instigated disasters" caused from anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanches, flooding, cold waves and heat waves, droughts, earthquakes, cyclones, landslides, lightning, tsunamis, volcanic activity, wildfires, and winter precipitation. Examples of anthropogenic hazards include criminality, civil disorder, terrorism, war, industrial hazards, engineering hazards, power outages, fire, hazards caused by transportation, and environmental hazards. Developing countries suffer the greatest costs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dam Failures In The United States
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.

Reservoirs In Iowa
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 ...

Hope Mills Dam
The Hope Mills Dam, also known as Hope Mills Dam #1, is a concrete gravity dam on Little Rockfish Creek in Hope Mills, North Carolina, USA, which created Hope Mills Lake. Four different dams were built on the site including the current one. The first dam, of rock-crib design, was built in 1839 to power local cotton mills. The second was an embankment dam built in 1924 for powering the mills and later to maintain the lake's water level. Both previous dams failed from flooding. Then in June 2010 a leak was discovered and the lake was drained. The current dam was completed in early 2018 and water to be impounded in January but rainwater filled the dam before water even needed to be impounded. History The first Hope Mills Dam was a rock-crib dam and was built in 1839 by the Rockfish Mills Co. for the powering of four cotton mills nearby. In 1865, General Sherman and Union Army troops burned the cotton mills but spared the dam from destruction. After the American Civil War, two mills w ...

Dam Failure
A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release. Between the years 2000 and 2009 more than 200 notable dam failures happened worldwide. A dam is a barrier across flowing water that obstructs, that directs or slows down the flow, often creating a reservoir, lake or impoundments. Most dams have a section called a ''spillway or weir'' over or through which water flows, either intermittently or continuously, and some have hydroelectricity, hydroelectric power generation systems installed. Dams are considered "installations containing dangerous forces" under International humanitarian law due to the massive impact of a possible destruction on the civilian population and the environment. Dam failures are comparatively rare, but can cause immense damage and loss of life when they occur. In 1975 the 1975 Banqiao Dam failure, failure of ...
