Document 2: Mahanoy Creek: Mahanoy Creek is a 51.6 mi tributary of the Susquehanna River in Northumberland and Schuylkill counties, Pennsylvania. There are at least 35 sources of acid mine drainage in the creek's watershed. Anthracite was mined in the upper part of the Mahanoy Creek watershed in the 19th and 20th centuries. Mahanoy Creek's tributaries include Schwaben Creek, Zerbe Run, Little Mahanoy Creek, Shenandoah Creek, and North Mahanoy Creek. Little Mahanoy Creek and Schwaben Creek are two streams in the watershed that are unaffected by acid mine drainage. Schwaben Creek has a higher number and diversity of fish species than the main stem.
Document 3: Saint John River (Bay of Fundy): The Saint John River (French: "Fleuve Saint-Jean" ; Maliseet: "Wolastoq"( )) is a river, approximately 418 mi long, located principally in the Canadian province of New Brunswick, but also in and arising from the province of Quebec and the U.S. state of Maine. It forms part of the Canada–United States border in two different places along its length. The river drains an area of approximately 55000 km2 , of which slightly more than half is located in New Brunswick. Along that portion of the Atlantic shoreline of North America that lies between the St. Lawrence River and the Mississippi River, the Saint John River is the second longest waterway; only the Susquehanna is longer. It has been nicknamed the "Rhine of North America" for its scenery. The river is regulated by hydro power dams located at Mactaquac, Beechwood, and Grand Falls, New Brunswick.
Document 4: Shickshinny Creek: Shickshinny Creek (historically known as Shickohinna) is a tributary of the Susquehanna River in the Wyoming Valley in Luzerne County, Pennsylvania, in the United States. It is approximately 10.1 mi long and flows through Ross Township, Union Township, and Shickshinny. Its watershed has an area of 35.0 sqmi and its tributaries include Culver Creek, Reyburn Creek, and Little Shickshinny Creek. The creek is designated as a Coldwater Fishery and a Migratory Fishery. A sawmill and a gristmill were built on the creek in 1802 and 1804, respectively. Several bridges have also been constructed over it. The creek was historically polluted by culm near its mouth, but agriculture was the main industry in the watershed in the early 1900s. It was historically used as a water supply.
Document 5: Chesapeake Bay: The Chesapeake Bay ( ) is an estuary in the U.S. states of Maryland and Virginia, lying inland from the Atlantic Ocean and surrounded to the west by the North American mainland and to the east by the Delmarva Peninsula. It is the largest estuary in North America. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64299 sqmi drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C.
Document 6: Six Mile Run Reservoir Site: The Six Mile Run Reservoir Site, part of the Delaware and Raritan Canal State Park, is located in Franklin Township, Somerset County, New Jersey, United States. It is adjacent to the Delaware and Raritan Canal. It covers 3037 acre . The reservoir plan was to flood the Six Mile Run watershed. The Six Mile Run is a tributary of the Millstone River that, with its tributaries (Cross Brook, Middlebush Brook, Nine Mile Run and Steep Hill Brook and several other unnamed ones), drains a large area in central Franklin Township, Somerset County, New Jersey and western portions of North Brunswick and South Brunswick Townships in Middlesex County, New Jersey. It derives its name, along with other streams (Mile Run, Three Mile Run, Nine Mile Run, and Ten Mile Run), from the distance early surveyors estimated it was from the point where the historic King's Highway (now Rt. 27) left the Raritan River at New Brunswick to the point the roadway crossed the stream. The estimates were not very accurate but the stream names have remained in use ever since.
Document 7: Kinney Run: Kinney Run, also known as Kinney's Run, is a tributary of the Susquehanna River in Scott Township and Bloomsburg, Columbia County, Pennsylvania, in the United States. It is approximately 3.1 mi long. Some of the first settlers to the Kinney Run area arrived in 1769. There are a number of wetlands and one bog, which is called the Espy Bog, in the stream's watershed.
Document 8: Potomac River: The Potomac River ( ) is located along the mid-Atlantic Ocean coast of the United States and flows into the Chesapeake Bay. The river (main stem and North Branch) is approximately 405 mi long, with a drainage area of about 14,700 square miles (38,000 km). In terms of area, this makes the Potomac River the fourth largest river along the Atlantic coast of the United States and the 21st largest in the United States. Over 5 million people live within the Potomac watershed.
Document 9: Santee River: The Santee River is a river in South Carolina in the United States, 143 mi long. The Santee and its tributaries provide the principal drainage for the coastal areas of southeastern South Carolina and navigation for the central coastal plain of South Carolina, emptying into the Atlantic Ocean approximately 440 mi from its farthest headwater on the Catawba River in North Carolina. The Santee River is the second largest river on the eastern coast of the United States, second only to the Susquehanna River in drainage area and flow. Much of the upper river is impounded by the expansive, horn-shaped Lake Marion reservoir, formed by the 8 mi -long Santee Dam. It was built during the Great Depression of the 1930s as a Works Progress Administration (WPA) project to provide a major source of hydroelectric power for the state of South Carolina.
Document 10: Rachel Carson Run: Rachel Carson Run is a 1.4 mi long tributary of the Allegheny River located in Allegheny County in the U.S. state of Pennsylvania. The stream is named after ecologist Rachel Carson.
Document 11: East River: The East River is a salt water tidal estuary in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, which is also on Long Island. Because of its connection to Long Island Sound, it was once also known as the "Sound River". The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths. The waterway is navigable for its entire length of 16 mi , and was historically the center of maritime activities in the city, although that is no longer the case.
