Prairie Du Sac Dam
The Prairie du Sac Dam is a hydroelectric dam on the Wisconsin River just north of Prairie du Sac, Wisconsin. It is owned and operated by Alliant Energy. The dam forms Lake Wisconsin. It is the last dam on the Wisconsin River before its confluence with the Mississippi River about downstream, and it marks the upper end of the Lower Wisconsin State Riverway. History The dam was designed by Daniel W. Mead for the Southern Wisconsin Power Company led by Magnus Swanson. The company had completed the Kilbourn Dam upriver at Wisconsin Dells in 1909, but found it unprofitable, leading to the decision to build a larger dam at Prairie du Sac. Construction of the new dam began in the winter of 1911 with general contractor J. O. Heyworth of Chicago and a crew of around 400 laborers. The construction of the Prairie du Sac Dam involved several engineering challenges. The width of the Wisconsin River and its bed of shifting sands required a deep foundation. Workers used steam-powered pil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Du Sac, Wisconsin
Prairie du Sac is a village in Sauk County, Wisconsin, United States. The population was 4,420 at the 2020 census. The village is surrounded by the Town of Prairie du Sac, the Wisconsin River, and the village of Sauk City; together, Prairie du Sac and Sauk City are referred to as Sauk Prairie. History Prairie du Sac was so named because it was in the large Wisconsin River Valley where the Sauk Indians had a large settlement. Although the name of the village dates from the early days of French fur traders, Prairie du Sac was established as a village by D.B. Crocker in 1840, largely as a Yankee-English village, in contrast to its neighbor, Sauk City, which was settled largely by Germans. The hydroelectric Prairie du Sac Dam was completed just north of the village in 1914, creating Lake Wisconsin. Geography Prairie du Sac is located at (43.289833, -89.728524). According to the United States Census Bureau, the village has a total area of , of which, of it is land and is water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trestle Bridges
A trestle bridge is a bridge composed of a number of short spans supported by closely spaced frames. A trestle support, trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used to support a stool or a pair of isosceles triangles joined at their apices by a Plank (wood), plank or beam (structure), beam such as the support structure for a trestle table. Each supporting frame is a bent (structural), bent. A trestle differs from a viaduct in that viaducts have towers that support much longer spans and typically have a higher elevation. Timber and iron trestles (i.e. bridges) were extensively used in the 19th century, the former making up from 1 to 3 percent of the total length of the average railroad. In the 21st century, steel and sometimes concrete trestles are commonly used to bridge particularly deep valleys, while timber trestles remain common in certain areas. Many timber trestles were built in the 19th and early 20th centuries with the exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Sauk County, Wisconsin
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 artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Wisconsin
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, human consumption, 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 dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PBS Wisconsin
PBS Wisconsin (formerly Wisconsin Public Television or WPT) is a state network of non-commercial educational television stations operated primarily by the Wisconsin Educational Communications Board and the University of Wisconsin–Madison. It comprises all of the Public Broadcasting Service (PBS) member stations in the state outside of Milwaukee (which has its own PBS stations.) The state network is available via flagship station WHA-TV in Madison and five full-power satellite stations throughout most of Wisconsin. As of April 5, 2009, all stations have converted to digital-only transmissions. PBS Wisconsin is also available on most satellite and cable television outlets. WHA-TV, along with Chicago, Illinois-based public television station WTTW-TV, serve the Rockford, Illinois television market exclusively through cable television and satellite television, as Rockford is one of a few television markets in the United States that lacks a PBS station of its own.

Tainter Gate
The Tainter gate is a type of radial arm floodgate used in dams and canal locks to control water flow. It is named for Wisconsin structural engineer Jeremiah Burnham Tainter. A side view of a Tainter gate resembles a slice of pie with the curved part of the piece facing the source or upper pool of water and the tip pointing toward the destination or lower pool. The curved face or skinplate of the gate takes the form of a wedge section of cylinder. The straight sides of the pie shape, the trunnion arms, extend back from each end of the cylinder section and meet at a trunnion which serves as a pivot point when the gate rotates. Pressure forces on a submerged body act perpendicular to the body's surface. The design of the Tainter gate results in every pressure force acting through the centre of the imaginary circle of which the gate is a section, so that all resulting pressure force acts through the pivot point of the gate, making construction and design easier. When a Tain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval ...

Micropile
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and caissons. Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering disciplin ...

Lake Delton
Lake Delton is a man-made freshwater lake in Sauk County in central Wisconsin. For much of 2008, it was a mostly empty lake basin after a portion of a county highway that forms part of the dike wall eroded on June 9, 2008, under the pressure of floods in the area. The resulting washout caused the lake to empty into the Wisconsin River, leaving behind only rainwater pools and the flow from Dell Creek. By March 2009, major repairs to correct the problem were completed, and the lake was allowed to refill. Minor repairs were expected to continue after that time, but the lake is now completely refilled and has been usable since Memorial Day weekend of 2009. The lake was formed in 1927 to attract tourists to the area and became a popular attraction in the Wisconsin Dells tourist area following the economic recovery after the Great Depression. Resorts and tourist attractions line its banks. The lake was the site of Tommy Bartlett's Thrill Show, which featured acrobatic water skiing ...

June 2008 Midwest Floods
The June 2008 Midwestern United States floods were flooding events which affected portions of the Midwestern United States. After months of heavy precipitation, a number of rivers overflowed their banks for several weeks at a time and broke through levees at numerous locations. Flooding continued into July. States affected by the flooding included Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri and Wisconsin. The American Red Cross assisted the victims of flooding and tornadoes across seven states and the National Guard was mobilized to assist in disaster relief and evacuation. Flooding continued as long as two weeks with central Iowa and Cedar Rapids being hardest hit. The upper Mississippi Valley experienced flooding in Missouri and Illinois as the region's estuaries drained the floodwater into the river. The flood left thirteen dead and damage region-wide was estimated to be in the tens of billions of dollars. Illinois On June 11, Illinois Governor Rod Blagojev ...
