Facts About The Bay of the Chesapeake
- The Susquehanna River 2The Chesapeake Bay is essentially the valley floor of the Susquehanna River. It is the Susquehanna’s tidal portion. Two integral parts of a single ecosystem are the river and the bay. During the last Ice Age, twenty thousand years ago, the sea level was about 330 ft. lower than it is today. The Susquehanna flowed from the edge of the polar ice cap (now northern central Pennsylvania) down to the Atlantic at that time. All of the rivers in what is now the drainage basin of the Chesapeake flowed into it. The Atlantic backed up into the Susquehanna’s valley floor as the earth warmed up and sea level rose, forming the Chesapeake Bay and the tidal portions of rivers like the Potomac and the Nanticoke. valley was formed nearly 12,000 years ago when glaciers melted and flooded;

Chesapeake Bay History
Chesapeake Bay, the largest inlet on the eastern U.S. Atlantic Coastal Plain. It is 193 miles (311 km) long and 3 to 25 miles (5 to 40 km) wide, created by the submergence of the lower courses of the Susquehanna River and its tributaries. Virginia borders the southern part of the bay, and Maryland borders its northern portion. Its entrance from the Atlantic is flanked to the north by Cape Charles and to the south by Cape Henry. In addition to the Susquehanna, the western James, York, Rappahannock, Potomac, and Patuxent and the eastern Wicomico, Nanticoke, Choptank, and Chester are major rivers emptying into the bay. Most of the irregular eastern shore of the bay is low and marshy, whereas the straighter west shore consists of cliffs for long distances.
The bay area’s first European settlement, Jamestown, was founded in 1607. One year later, Captain John Smith, the English colonist, explored and mapped the bay and its estuaries, and soon after, settlers came to the easily accessible, well-protected shores of the bay.
The British invaded the Chesapeake Bay during the War of 1812. Near Annapolis, Maryland, the William Preston Lane, Jr., Memorial Bridge spans the upper bay. It was opened in 1952 to traffic and is 6.4 km (4 miles) long.
The Bridge-Tunnel of the Chesapeake Bay was completed in 1964 across the lower bay. The Atlantic Intracoastal Waterway forms part of the bay. The sheltered, nutrient-rich waters of the Chesapeake Bay supported vast populations of fish, shellfish and other marine life until the latter half of the 20th century. There was an abundance of commercial fishing and recreational activities. However by the 1970s, the surrounding land’s residential and industrial development had led to significant pollution of the bay by sewage, industrial waste, and sediment. During the 1970s and into the 1980s, commercial fishing dropped sharply, as did recreational use of the bay. In an effort to reverse the environmental damage that the bay has suffered, various projects have been undertaken. britannica.com – Chesapeake Bay
