Conejohela Flats
The Conejohela Flats are a group of islands in the flooded Conejohela Valley, a large floodplain along the southernmost 30 miles (50 km) of the Susquehanna River in Pennsylvania and Maryland in the United States. The valley was flooded primarily during the early 1900s by the construction of the Holtwood, Conowingo, and Safe Harbor dams from 1910 to 1931. Geography and history Before the twentieth century, the Conejohela Valley was a marshy floodplain, with extensive wetlands. The Susquehanna River flooded annually in the spring, and there were more damaging floods approximately once per decade. Thick forests surrounded a mixture of small waterfalls, rapids, and marshes. A wide, flat valley formed; the frequently wide river was a substantial barrier to crossing, both for Native Americans and for colonists. The varied terrain created many nurturing biological habitats, but human passage across the valley and river was extremely difficult. The Susquehanna is very wide in this ...

Lake Clarke
Lake Clarke in Pennsylvania is a man-made lake along the Susquehanna River formed by the Safe Harbor Dam, a public works project of the 1930s Great Depression and one of the electrification projects of the New Deal. It is approximately long centered within the Conejohela Valley approximately downstream of historic Wright's Ferry (1630−1901). Safe Harbor Water Power Corporation provides picnic areas, boat ramps, playgrounds and other public recreation facilities at several locations on both sides of the lake. Lake Clarke is home to Long Level Marina, Safe Harbor's boat-access areas, Susquehanna Yacht Club, Lake Clarke Rescue Inc., and two private marinas that are located on the York County side of the lake. The United States Coast Guard Auxiliary has several flotillas of Division 19 (5th District Northern Region (NR)) that patrol the area of Lake Clarke and is based out of Station Long Level located on the York side of the lake.

Landforms Of Lancaster County, Pennsylvania
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography.

Thomas Cresap
Colonel Thomas Cresap (17021790) was an English-born settler and trader in the states of Maryland and Pennsylvania. Cresap served Lord Baltimore as an agent in the Maryland–Pennsylvania boundary dispute that became known as Cresap's War. Later, together with the Native American chief Nemacolin, Cresap improved a Native American path to the Ohio Valley, and ultimately settled and became a large landowner near Cumberland, Maryland, where he was involved in further disputes near Brownsville, Pennsylvania, including in the French and Indian War and Lord Dunmore's War. Early life Cresap was born in Skipton, Yorkshire, England, and emigrated across the Atlantic Ocean to the Maryland colony when he was 15 years old. In 1723, he gave his occupation as that of a carpenter. He initially settled at the mouth of the Susquehanna River on the Chesapeake, on the lower end of a floodplain called the Conejohela Valley, and built boats. In 1725, Cresap married Hannah Johnson, whose father, T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Susquehanna River Dams
The Susquehanna River, in the Mid-Atlantic States of the United States, has a collection of dams. These dams are used for power generation, flood control, navigation and recreation. These dams have local and regional environmental impacts on the river and the Chesapeake Bay, both positive and negative. Environmental impacts :''And by making it more Susquehanna specific.'' The dams have a positive impact on the environment. They slow water, trapping silt and pollutants. Conowingo Dam is credited with preventing much of the silt from Pennsylvania from reaching the Chesapeake Bay. The dam spillways can add oxygen to the water. The down stream side of dams is favored by aquatic birds, possibly because the fish that pass through the dam are a bit stunned. Conowingo Dam is noted for its bald eagles. Hydroelectric power is considered an environmentally friendly method of power generation. The dams also make a negative impact on the environment. They raise the water level, a ...

Cresap's War
Cresap's War (also known as the Conojocular War, from the Conejohela Valley where it was mainly located along the south bank) was a border conflict between Pennsylvania and Maryland, fought in the 1730s. Hostilities erupted in 1730 with a series of violent incidents prompted by disputes over property rights and law enforcement, and escalated through the first half of the decade, culminating in the deployment of military forces by Maryland in 1736 and by Pennsylvania in 1737. The armed phase of the conflict ended in May 1738 with the intervention of King George II, who compelled the negotiation of a cease-fire. A final settlement was not achieved until 1767 when the Mason–Dixon line was recognized as the permanent boundary between the two colonies. Background Pennsylvania's Charter (1681) specified that the colony was bounded "on the South by a Circle drawne at twelve miles 9 kmdistance from New Castle Northward and Westward unto the beginning of the fortieth degree of No ...

Riparian
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Game Fish
Game fish, sport fish or quarry refer to popular fish pursued by recreational anglers, and can be freshwater or saltwater fish. Game fish can be eaten after being caught, or released after capture. Some game fish are also targeted commercially, particularly salmon and tuna. Specimens of game fish whose measurements (body length and weight) are a lot above the species' average are sometimes known as trophy fish. Examples The species of fish prized by anglers varies with geography and tradition. Some fish are sought for their value as food, while others are pursued for their fighting abilities, or for the difficulty of successfully enticing the fish to bite the hook. * Big-game fish are blue water saltwater bony fish such as tuna, tarpon, grouper and billfish (sailfish, marlin and swordfish). Occasionally other predatory fishes such as sharks, barracuda and dolphinfish are also pursued. * In North America, many anglers fish for common snook, redfish, salmon/trout, bass, no ...

Amtrak's 25 Hz Traction Power System
Amtrak's 25 Hz traction power system is a Traction power network, traction power grid operated by Amtrak along the southern portion of its Northeast Corridor (NEC): the 226.6 route miles (362 km) between Washington, D.C. and New York City and the 104 route miles (167 km) between Philadelphia and Harrisburg, Pennsylvania. The Pennsylvania Railroad constructed it between 1915 and 1938. Amtrak inherited the system from Penn Central, the successor to the Pennsylvania Railroad, in 1976, along with the Northeast Corridor. This is the reason for using 25 Hz, as opposed to 60 Hz, which is the standard for power transmission in North America. In addition to serving the NEC, the system provides power to NJ Transit Rail Operations (NJT), the SEPTA, Southeastern Pennsylvania Transportation Authority (SEPTA) and the MARC Train, Maryland Area Regional Commuter Train (MARC). Only about half of the system's electrical capacity is used by Amtrak. The remainder is sold to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
