Copco 1, the oldest of the three remaining dams on the Klamath River, was successfully breached Tuesday. Crews blasted a plug in Copco’s adit tunnel, a 10-foot diameter tunnel that was drilled at the base of the dam last summer. … Earlier this year, openings were created at the two other hydroelectric dams, Iron Gate and John C. Boyle, as part of drawing down water from the reservoirs behind the dams. A fourth dam, Copco 2, was removed last year.
