Only a few remnants of the Toluca Coal Mine still exist today, including a concrete rectangle that during mining operations served as a water reservoir used to cool the steam engines. A 6-inch diameter pipe carried water from the open well, supplied by gravitation from the pond, to the steam engines working shaft #1 in the boiler house. After World War I, the American Legion and the Toluca City Council turned the reservoir into a community swimming pool, charging $2.50 for a season ticket. The buildings in the background housed a dressing area and concession stand. Toluca's population in 1923 was about 1400. Today, the area is referred to as the pool and serves as a central meeting point for many community events, wiener roasts, and birthday parties.
