The Marys River is a river in western Oregon that flows for approximately 41 miles from the Coast Range to the Willamette River. It was named after a Native American tribe that lived in the area. The river has historically been used for fishing by the local tribes and later for logging and transportation. It also has been a source of water for agriculture and drinking water for nearby towns. The river is dammed at two locations, the first being the Marys River Dam, which creates the Starker Reservoir, and the second being the Woods Creek Dam, which creates the Woods Creek Reservoir. These reservoirs are used for water storage, flood control, and hydroelectric power generation. The Marys River is a popular spot for recreation, including fishing, kayaking, and hiking along its banks.

History of the River

The St. Marys River (named Saint Marys River by the USGS, and sometimes misspelled as St. Mary's River) is a 126-mile-long (203 km) river in the southeastern United States. From near its source in the Okefenokee Swamp, to its mouth at the Atlantic Ocean, it forms a portion of the border between the U.S. states of Georgia and Florida. The river also serves as the southernmost point in the state of Georgia.
The St. Marys River rises as a tiny stream, River Styx, flowing from the western edge of Trail Ridge, the geological relic of a barrier island/dune system, and into the southeastern Okefenokee Swamp. Arching to the northwest, it loses its channel within the swamp, then turns back to the southwest and reforms a stream, at which point it becomes the St. Marys River. Joined by another stream, Moccasin Creek, the river emerges from Okefenokee Swamp at Baxter, Florida/Moniac, Georgia. It then flows south, then east, then north, then east-southeast, finally emptying its waters into the Atlantic, near St. Marys, Georgia and Fernandina Beach, Florida.
