Lake Mattamuskeet Pump Station, Pumping station at Lake Mattamuskeet, Hyde County, United States.

Lake Mattamuskeet Pump Station is a three-story brick building of 14,977 square feet on the shore of Lake Mattamuskeet. It is connected to a 120-foot-high tower with a stairway. Built in 1911, it now stands within Mattamuskeet National Wildlife Refuge near Swan Quarter.

The station was built in 1911 as the world's largest pumping facility at that time, designed to drain agricultural lands around the lake. The federal government acquired it in 1934 and converted the structure into a hotel and administrative headquarters for the growing wildlife refuge program.

The building is known locally as Mattamuskeet Lodge, a name it took on after its 1934 conversion into a hotel and refuge headquarters. Visitors can still see the 120-foot tower with its stairway, a remnant of the original pumping works.

The site sits near Swan Quarter on the eastern shore of the lake and can be visited through the wildlife refuge visitor center. The building and surrounding refuge offer walking trails and observation areas for exploring the landscape and watching local wildlife.

The 120-foot tower is reached by a stairway inside the brick building, and the structure covers 14,977 square feet across three floors. It was listed on the National Register of Historic Places in 1980, the same year its pumping days were long over.
