Oneida Number One Tunnel

The Oneida Number One Tunnel (also known as the Oneida Tunnel 1 or the Oneida #1 Tunnel) is a mine drainage tunnel in Schuylkill County, Pennsylvania, in the United States. It is one of five major mine tunnels in the watershed of Catawissa Creek. The tunnel discharges into Sugarloaf Creek near Lake Choctaw and Lake Susquehanna. The water quality of the tunnel's discharge has improved significantly since the installation of a treatment system at the site of the tunnel in 2001.
