Splash Dam
A splash dam was a temporary wooden dam used to raise the water level in streams to float logs downstream to sawmills. By impounding water and allowing it to be released on the log drive's schedule, these dams allowed many more logs to be brought to market than the natural flow of the creek allowed. Water releases from multiple splash dams on tributaries were also often combined to maximize the number of logs floated throughout a given watershed. Construction Splash dams were typically constructed of logs or boards, which formed cribs that were then filled with stones and earth. They could be anywhere from to several hundred feet wide, and were used from one to several years. A splash dam had to be sited on a section of the stream that allowed as large a body of water to accumulate behind the dam as possible. Behind the dam logs were transported to the creek and its banks, often along log slides. (No ISBN) The splash dam was equipped with a chute to allow water and logs to esc ...

Board Feet
The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada. It equals the volume of a length of a board, one foot wide and thick. Board foot can be abbreviated as FBM (for "foot, board measure"), BDFT, or BF. A thousand board feet can be abbreviated as MFBM, MBFT, or MBF. Similarly, a million board feet can be abbreviated as MMFBM, MMBFT, or MMBF. Until 1970s in Australia and New Zealand the terms super foot and superficial foot were used with the same meaning. One board foot equals: * 1 ft × 1 ft × 1 in * 12 in × 12 in × 1 in * 144 in3 * 1/12 ft3 * ≈ * ≈ * ≈ or steres * 1/1980 Petrograd Standard of board The board foot is used to measure rough lumber (before drying and planing with no adjustments) or planed/surfaced lumber. An example of planed lumber is softwood 2 × 4 lumber sold by large lumber retailers. The 2 × 4 is actually only , but the dimensions for the lumber when purchased wholesa ...

Parker Dam State Park
Parker Dam State Park is a Pennsylvania state park in Huston Township, Clearfield County, Pennsylvania in the United States. The park is surrounded by Moshannon State Forest. Parker Dam State park is north of Clearfield on Pennsylvania Route 153 just off exit 111 of Interstate 80. The park was constructed during the Great Depression by the Civilian Conservation Corps; they built many of the facilities that are in use today at Parker Dam State Park. History The park takes its name from William Parker, who leased lumbering rights from John Otto. Parker built a splash dam on Laurel Run at the site of the present lake. Lumbering began as early as 1794 in Clearfield County, harvesting the white pine and hemlock which covered the mountainsides. The tall white pines fetched a high price in Baltimore for use as masts. Logs were to Baltimore by way of the Susquehanna River. Logging picked up in force during the 1850s when the Susquehanna Boom was built across the West Branch Susqu ...

List Of Pennsylvania State Parks
There are 124 state parks in the U.S. state of Pennsylvania . The Pennsylvania Bureau of State Parks, a division of the Pennsylvania Department of Conservation and Natural Resources (DCNR), is the governing body for all these parks, and directly operates 116 of them. The remaining eight are operated in cooperation with other public and private organizations. The first Pennsylvania state park, at Valley Forge, opened in 1893 and was given to the National Park Service (NPS) for America's bicentennial in 1976. There are a total of seventeen former Pennsylvania state parks: four former parks have been transferred to the NPS, four to the Pennsylvania Historical Museum Commission, two to the U.S. Army Corps of Engineers, one to both the Corps and the Pennsylvania Game Commission, five to the Pennsylvania Bureau of Forestry, and one has ceased to exist. Nine current and two former state parks have had major name changes or have been known under alternate names. The list gives an overvie ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dam For Flooding Logs, L
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] |
Photograph Of A Dam For Making Freshet For Floating Logs In Northern Michigan - NARA - 2129578
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
