Is Mirror Lake a real lake?
Originally, a spring supplied much of the water for Mirror Lake and was a source of drinking water for both the campus and people living nearby. A city sewer was constructed in the ravine in 1891 on the south side of the lake, but it was so poorly built that the lake and spring disappeared. The sewer was reconstructed in 1892 and water once again flowed through the spring. The increasing coverage of the ground surface by campus buildings and paved areas permanently dried up the spring in the 1920s. After that time, well water, river water, and city water became the sources used to feed water into the lake. The lake holds 91,000 cubic feet of water.
