Jamestown Dam
The Jamestown Dam is a rolled-earth dam spanning the James River in Stutsman County in the U.S. state of North Dakota, serving the primary purpose of flood control. It is north of the city of Jamestown, North Dakota. Built from April 1952 to September 1953, the dam measures long at the crest and high. It impounds the James River to form the Jamestown Reservoir. A small islet lies shortly upstream of the dam, where the James River previously split into two channels. The dam and reservoir rest on a wide plain of shale where the James River cut a canyon up to wide and deep. The shale (called Pierre Shale) has a dark gray, bedded appearance, and is mostly claystone or siltstone. The valley also contains many traces of alluvium, mainly deposited during the last ice age when the area was heavily glaciated. Construction Proposal and companies involved The dam was proposed in 1951. The site selected offered the required storage with the smallest dam and with close access to embankme ...

Stutsman County, North Dakota
Stutsman County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 21,593, and was estimated to be 21,546 in 2024, making it the 8th-most populous county in North Dakota. Its county seat is Jamestown. Stutsman County comprises the Jamestown, North Dakota micropolitan statistical area. History The Dakota Territory legislature created the county on January 4, 1873, with area partitioned from Buffalo and Pembina counties. It was not organized at that time, nor was it attached to another county for administrative or judicial purposes. It was named for Enos Stutsman, an area lawyer and politician. On June 10 of the same year, the county organization was effected, with Jamestown as the county seat. Its boundaries have not changed since its creation. Geography The James River flows south-southeasterly through the east central part of the county. The terrain consists of low rolling hills, dotted with lakes and ponds in its western portion. ...

Outlet Works
A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very elaborate. Background A set of outlet works is a device used to release and regulate water flow from a dam. Such devices usually consist of one or more pipes or tunnels through the embankment of the dam, directing water usually under high pressure to the river downstream. These structures are usually used when river flow exceeds the capacity of the power plant or diversion capacity of the dam, but is not high enough to warrant use of the dam spillways. They may also be used when river flows must be bypassed due to maintenance work in the power station or diversion gates. Although similar in purpose to spillways, outlet works provide a more controlled release to meet downstream flow requirements. A typical ...

Camping
Camping is a form of outdoor recreation or outdoor education involving overnight stays with a basic temporary shelter such as a tent. Camping can also include a recreational vehicle, sheltered cabins, a permanent tent, a shelter such as a Bivy bag, bivy or Tarpaulin, tarp, or no shelter at all. Typically, participants leave developed areas to spend time outdoors, in pursuit of activities providing them enjoyment or in a form of educational experience. Spending the night away from home distinguishes camping from Day trip, day-tripping, picnicking, and other outdoor activities. Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. In a few countries, including Sweden and Scotland, public camping is legal on privately held land as well. Camping i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relief Well
Relief is a sculptural method in which the sculpted pieces remain attached to a solid background of the same material. The term ''relief'' is from the Latin verb , to raise (). To create a sculpture in relief is to give the impression that the sculpted material has been raised above the background plane. When a relief is carved into a flat surface of stone (relief sculpture) or wood ( relief carving), the field is actually lowered, leaving the unsculpted areas seeming higher. The approach requires chiselling away of the background, which can be time-intensive. On the other hand, a relief saves forming the rear of a subject, and is less fragile and more securely fixed than a sculpture in the round, especially one of a standing figure where the ankles are a potential weak point, particularly in stone. In other materials such as metal, clay, plaster stucco, ceramics or papier-mâché the form can be simply added to or raised up from the background. Monumental bronze reliefs ar ...

Bureau Of Reclamation
The Bureau of Reclamation, formerly the United States Reclamation Service, is a List of United States federal agencies, federal agency under the U.S. Department of the Interior, which oversees water resource management, specifically as it applies to the oversight and operation of the diversion, delivery, and storage projects that it has built throughout the western United States for irrigation, water supply, and attendant hydroelectric power generation. It is currently the U.S.'s largest wholesaler of water, bringing water to more than 31 million people, and providing one in five Western farmers with irrigation water for 10 million acres of farmland, which produce 60% of the nation's vegetables and 25% of its fruits and nuts. The Bureau is also the second largest producer of hydroelectric power in the western U.S. On June 17, 1902, in accordance with the Reclamation Act, United States Secretary of the Interior, Secretary of the Interior Ethan A. Hitchcock (Interior), Ethan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

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] |
Riprap
Riprap (in North American English), also known as rip rap, rip-rap, shot rock, rock armour (in British English) or rubble, is human-placed rock or other material used to protect shoreline structures against scour and water, wave, or ice erosion. Riprap is used to armor shorelines, streambeds, bridge abutments, foundational infrastructure supports and other shoreline structures against erosion. Common rock types used include granite and modular concrete blocks. Rubble from building and paving demolition is sometimes used, as well as specifically designed structures called ''tetrapods'' or similar concrete blocks. Riprap is also used underwater to cap immersed tubes sunken on the seabed to be joined into an undersea tunnel. Environmental effects Sediment effects Riprap causes morphological changes in the riverbeds they surround. One such change is the reduction of sediment settlement in the river channel, which can lead to scouring of the river bed as well as coarser sedime ...

Foundation (nonprofit Organization)
A foundation (also referred to as a charitable foundation) is a type of nonprofit organization or charitable trust that usually provides funding and support to other charitable organizations through grants, while also potentially participating directly in charitable activities. Foundations encompass public charitable foundations, like community foundations, and private foundations, which are often endowed by an individual or family. Nevertheless, the term "foundation" might also be adopted by organizations not primarily engaged in public grantmaking. Description Legal entities existing under the status of "foundations" have a wide diversity of structures and purposes. Nevertheless, there are some common structural elements. * Legal requirements followed for establishment * Purpose of the foundation * Economic activity * Supervision and management provisions * Accountability and auditing provisions * Provisions for the amendment of the statutes or articles of incorporation * ...
