Mark Twain Lake
Mark Twain Lake is a reservoir located in Ralls and Monroe Counties in the U.S. state of Missouri. It was created by the Clarence Cannon Dam (formerly called ''Joanna Dam'') impounding the Salt River and is located about southwest of Hannibal. The lake was named for Missouri author Mark Twain and part of the area around it is Mark Twain State Park. The village of Florida, the birthplace of Mark Twain, is mostly surrounded by the lake. Authorization and purpose In 1937 the Joanna Dam project was first proposed as an answer to many years of flooding by the Salt River. With support and expertise of many, including Representative Clarence Cannon, the multi-purpose project was authorized by Congress in the Flood Control Act of October 1962. The dam and the lake offer multiple benefits to Northeast Missouri including: hydroelectricity, flood Control, recreation, fish and wildlife conservation, water supply (shortage of existing ground water), navigation. The dam was dedicated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt River (Missouri)
The Salt River is a tributary of the Mississippi River in eastern Missouri in the United States. The river is approximately long and drains an area of in parts of twelve Missouri counties. It rises at the confluence of the North, Middle, and South Forks in Monroe County. Since Clarence Cannon Dam construction was completed in 1983, the first 15 miles of the Salt River after the confluence of the North, Middle, and South Fork have been contained in Mark Twain Lake Mark Twain Lake is a reservoir located in Ralls and Monroe Counties in the U.S. state of Missouri.

Monroe County, Missouri
Monroe County is a county in northeast Missouri. As of the 2020 census, the population was 8,666. Its county seat is Paris. It is the birthplace of Mark Twain. History The county was organized January 6, 1831 and named for James Monroe, the fifth President of the United States. Monroe County was one of several along the Missouri River settled by migrants from the Upper South, especially Kentucky and Tennessee. They brought slaves and slaveholding traditions with them and quickly started cultivating crops similar to those in Middle Tennessee and Kentucky: hemp and tobacco. They also brought characteristic antebellum architecture and culture. The county was at the heart of what was called Little Dixie.

Wildlife
Wildlife refers to domestication, undomesticated animal species (biology), species, but has come to include all organisms that grow or live wilderness, wild in an area without being species, introduced by humans. Wildlife was also synonymous to game (hunting), game: those birds and mammals that were trophy hunting, hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is human impact on the environment, affected by human behavior, human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature. Humans have historically t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Missouri
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 ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crigler Mound Group
The Crigler Mound Group is an important archaeological site in the northeastern part of the U.S. state of Missouri. Located in the Salt River valley near Mark Twain Lake, these burial mounds have been named a historic site. In the 1960s, the Crigler mounds were seemingly the largest and best-preserved group within what was soon projected to become the Joanna Reservoir. The site occupies a high hilltop approximately north of the original Salt River bed. Composed of seven large mounds, the entire group covers an area nearly long,Henning, Dale R.

Tumulus
A tumulus (plural tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or ''kurgans'', and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus. Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a round tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows has a broad range; the categorization only refers to the external apparent shape. The method of may involve a dolmen, a cist, a mortuary enclosure, a mortuary house, or a chamber tomb. Examples of barrows include Duggleby Howe and Maeshowe. Etymology The word ''tumulus'' is Latin for 'mound' or 'small hill', which is derived from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angling
Angling is a fishing technique that uses a fish hook or "angle" (from Old English ''angol'') attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. When ...

Samuel Clemens
Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher, and lecturer. He was praised as the "greatest humorist the United States has produced", and William Faulkner called him "the father of American literature". His novels include ''The Adventures of Tom Sawyer'' (1876) and its sequel, ''Adventures of Huckleberry Finn'' (1884), the latter of which has often been called the "Great American Novel". Twain also wrote ''A Connecticut Yankee in King Arthur's Court'' (1889) and ''Pudd'nhead Wilson'' (1894), and co-wrote The Gilded Age: A Tale of Today (1873) with Charles Dudley Warner. Twain was raised in Hannibal, Missouri, which later provided the setting for ''Tom Sawyer'' and ''Huckleberry Finn''. He served an apprenticeship with a printer and then worked as a typesetter, contributing articles to the newspaper of his older brother Orion Clemens. He later became a riverboat ...

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.
