Watershed Park is a 153-acre temperate rain forest public park located in Olympia, Washington that supplied almost all the city's water from privately established wells in the late 1800s. The city acquired and operated the wells starting in 1917 until the 1950s when the municipal water source was replaced. In 1955 the forest was to be logged and the land sold but strong local opposition resulted in an ordinance preserving the area as a city park. Throughout, remnants of the waterworks are visible from the park trails.
