With U.S. Rep. Tom McClintock, R-Roseville, pledging to continue the drive to one day build the long-delayed Auburn dam, the Auburn Area Democratic Club will be presenting arguments Thursday for not going ahead with the project. Laird Thompson, a geologist, environmentalist and Auburn-area resident, will speak on potential geologic and ecological hazards associated with its construction. Thompson will speak at a meeting that starts at 7 p.m. March 3 in the Auburn Library, 350 Nevada St., Auburn. Paul Berger, representative-at-large with the club, said although McClintock has been invited to speak in favor of the dam, he has not replied and is not expected to be at the meeting. “I’d be floored if he shows up,” Berger said. The dam, which would be located in the canyon adjacent to Auburn, was authorized by Congress in 1965. Work was halted in the 1970s due to earthquake concerns and then spending cutbacks.
