Camp Coldwater
Camp Coldwater is an area of several springs that are important to Native Americans, as well as an early European settlement in the state of Minnesota, USA. Camp Coldwater is located adjacent to the Mississippi River in south Minneapolis, directly south of Minnehaha Park.
The camp was explored by early European settlers who were in the process of building Fort Snelling. On May 5, 1820, Lieutenant Colonel Henry Leavenworth moved his troops to the area because their former encampment, on the Minnesota River, was causing unhealthy conditions. Due to the presence of Escherichia coli in the waters, which was unknown until 1895, the water there was also contaminated, like the Minnesota River . He was succeeded by Colonel Josiah Snelling in August of that year. The soldiers lived in tents and huts on the site during three summers while they built the permanent stone fort south of the location. The spring continued to supply water to the fort, first via water wagons and then via a stone water tower and underground pipes. Settlers who had left the Red River Colony settled near the location in 1821, but were forced to leave in 1840. They moved down the Mississippi River and settled in what eventually became Saint Paul, Minnesota. The Coldwater area once housed blacksmith shops, stables, trading posts, a hotel, and a steamboat landing, but nearly all of those buildings were gone by the time of the American Civil War.
The Minnesota Department of Transportation set a national precedent in 2003 by welding 28,000 square yards of eight-layer synthetic liner, covering approximately six acres to protect the water flow to the spring. The liner isolated the Hwy 55/62 interchange, allowing it to sit below the water table and remain dry, while also letting the water flow beneath the interchange to the spring.
The Coldwater site is located on the United States Bureau of Mines property east of Minnesota State Highway 55. The property was transferred to the National Park Service in 2010, and made a unit of the Mississippi National River and Recreation Area.
