A history of the Altoona Reservoir system located alongside the Horseshoe Curve railroad tracks.

“The Altoona Reservoir System stands today as a remarkable example of outstanding 19th century waterworks engineering. Located near the base of the Allegheny Mountains where trains make their climb westward by way of the world famous Horseshoe Curve, an integrated system of dams, loevees, channels, tunnels, and weirs were designed to provide not only capacity, but enhanced water quality. This system is still functioning as designed and still serving the region over 135 years later.”
