The Susquehanna River, in the Mid-Atlantic States of the USA, has a collection of dams. The Susquehanna River (originally "Sasquesahanough" per the 1612 John Smith map is a River located in the northeastern United States. The Mid-Atlantic States (also called Middle Atlantic States or simply Mid Atlantic) form one of the nine geographic divisions within the United States that The United States of America —commonly referred to as the A dam is a barrier that divides waters. Dams generally serve the primary purpose of retaining water while other structures such as Floodgates, Levees These dams are used for power generation, flood control, navigation and recreation. Electricity generation is the process of converting non-electrical Energy to Electricity. Flood control is a feature of many communication protocols designed to prevent overwhelming of a destination receiver Navigation is the process of reading and controlling the movement of a craft or vehicle from one place to another Recreation or fun is the expenditure of time in a manner designed for therapeutic refreshment of one's Body or Mind. These dams have local and regional environmental impacts on the river and the Chesapeake Bay, both positive and negative. The Chesapeake Bay is the largest Estuary in the United States.

Environmental impacts

And by making it more Susquehanna specific.
For more details on this topic, see Conowingo Dam. The Conowingo Dam (also Conowingo Hydroelectric Plant, Conowingo Hydroelectric Station) is a large Hydroelectric Dam in the Lower Susquehanna

The dams have a positive inpact on the environment. They slow water sections created trap silt and pollutants. Conowingo Dam is credited with preventing much of the silt from Pennsylvania from reaching the Chesapeake Bay. The Conowingo Dam (also Conowingo Hydroelectric Plant, Conowingo Hydroelectric Station) is a large Hydroelectric Dam in the Lower Susquehanna 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. The Bald Eagle ( Haliaeetus leucocephalus) is a Bird of prey found in North America that is most recognizable as the national bird and Hydroelectric power is considered an environmentally friendly method of power generation. Hydroelectricity is electricity generated by Hydropower, ie the production of power through use of the gravitational force of falling water

The dams also make a negative impact on the environment. They raise the water level, altering the riparian environment. The upstream pools can become environmentally unsound below the surface, especially during summer. They block migratory fish, such as the American shad. The American shad or Atlantic shad, Alosa sapidissima, is a Species of Anadromous Fish in family Clupeidae The dams from York Haven down to the Chesapeake all have fish ladders or lifts to mitigate this. Fishways, most commonly called fish ladders but also known as fish passes and in Australia also referred to as fish steps, are structures on or around artificial Fishways, most commonly called fish ladders but also known as fish passes and in Australia also referred to as fish steps, are structures on or around artificial

Human impacts

And by making it more Susquehanna specific.

The dams have both a positive and negative impact on human society, outside of the environmental impacts above.

River dams have long been associated with power generation. In the past dams powered mills directly. Today dams are used both for direct hydroelectric generation and to form pools for cooling other forms of generation. Dams create navigable stretches of river where they may have been unnavigable before. The first dams at Sunbury, Pennsylvania were to support year round ferry crossings. Sunbury (pronounced Sunberry is a city in Northumberland County, Pennsylvania, United States.

The creation of dams does have negative impacts. Communities on the river edge are displaced, such as Conowingo, Bald Friar, and Glen Cove, Maryland in 1928. Conowingo is a small community in western Cecil County Maryland, USA. Year 1928 ( MCMXXVIII) was a Leap year starting on Sunday (link will display full calendar of the Gregorian calendar. Longitudinal river navigation is impeded. Although the historic Susquehanna was very difficult to navigate most of the year. Timber rafts could come down in the spring high water, but very few boats went up the river, before the canals were built. The Conowingo Dam is located near "Smith's Falls", where John Smith had to turn back while exploring the region in the early 1600s due to the impassable rapids. Captain Sir John Smith (c January 1580– June 21 1631) Admiral of New England was an English Soldier, Sailor
