PacifiCorp announced on Tuesday that it will repair the leak in Mirror Pond dam in April, in time for people to enjoy higher water levels on the Deschutes River this summer.
One of the wooden panels in the dam began leaking in October, and since then, the water level has sunk, leaving visible the mud flats that have been building up in the Mirror Pond section of the river. The utility stopped generating power at the dam after it discovered the leak, and executives have been meeting with a Bend city councilor and the executive director of the Bend Park & Recreation District to discuss the possibility of transferring ownership of the dam to a government agency.
PacifiCorp plans to install a steel sheet piling upstream of the leaking panel, according to a news release from the utility.
Once the dam is repaired, PacifiCorp will again begin generating electricity at the dam, Mark Tallman, PacifiCorp’s vice president for renewable resources, said in the release.
Tallman also said it is possible Mirror Pond would have filled up anyway this summer, when more water will be released from Wickiup Reservoir.
In December, PacifiCorp spokesman Bob Gravely said it would not be cost effective to repair the dam because it produced a meager amount of electricity. On Tuesday, Gravely said utility executives decided to repair the dam for different reasons.
Gravely said PacifiCorp hopes that repairing the dam will make it easier for the utility and local officials to reach an agreement to transfer the dam to a local government agency. “We don’t intend to generate (electricity) long-term, so fixing one leak for that purpose wouldn’t make sense.”
Gravely said PacifiCorp estimates that fixing the leak will cost $250,000.
Park district Executive Director Don Horton recently called for PacifiCorp to repair the dam to prevent further damage to the structure and ensure the river will be safe for boaters and others recreating on the river this summer.
Regarding PacifiCorp’s announcement, Horton said, “It shows that PacifiCorp has been listening to the community’s needs and trying to do their part in this negotiation process that we’re going through, to figure out a long-term solution to Mirror Pond and the dam.”
PacifiCorp also met privately on Tuesday afternoon with City Councilor Mark Capell and Horton to continue negotiating a possible transfer of ownership of the dam. Capell and Horton are members of the Mirror Pond ad hoc committee tasked with deciding the future of the pond. They were joined in the negotiating session by Ned Dempsey, a citizen member of the committee. Dempsey is a civil engineer who owns a home across from Drake Park.
The committee is scheduled to meet at 1 p.m. today to discuss a proposal from committee member and park board Chairman Scott Wallace to appoint Dempsey to the small group that is meeting with PacifiCorp. However, Horton said Tuesday that Wallace went ahead and appointed Dempsey without waiting for a public meeting.
Capell said that during the meeting Tuesday, Bend officials and PacifiCorp discussed proposals from firms that want to conduct an independent inspection of the dam on behalf of the park district. Capell had to leave the meeting during discussion of a proposal from HDR, a large engineering firm where Capell’s brother Paul Capell works. Capell has said PacifiCorp should repair the Mirror Pond dam and give it to the community, and on Tuesday, he said the announcement that the utility will repair the dam does not mean it will be worth more. “It’s not going to make them any money, for sure,” Capell said. Nonetheless, Capell said the utility’s decision to fix the leak is a positive development. “I thought that was an outstanding step forward by (PacifiCorp),” Capell said.
