Removal of Cline Falls Dam on Deschutes underway
Removal of the more than 100-year-old wood and concrete dam, along with hydroelectric equipment, at Cline Falls on the Deschutes River near Redmond is underway and is expected to continue through the end of August, officials said Monday.
Once completed, resident trout and wildlife will be able to migrate freely through the former dam site, accessing river and riparian habitat along the Upper Deschutes, the Central Oregon Irrigation District said in a news release.
Crews have installed a cofferdam, a temporary watertight enclosure that allows the enclosed area to be pumped out. This pumping creates a dry work environment for the dam removal to proceed. Beginning Monday, an excavator with an air-chisel attachment will be used to demolish sections of the dam.
“As owners of the land we’ve been committed to removing this dam for years in an effort to return the Deschutes River to its natural state,” said Craig Horrell, manager of the Central Oregon Irrigation District. “To finally see the dam removal and site clean-up in action was a very proud moment for our organization.”
Following a successful settlement with Pacificorp, who previously leased the site from COID, the Cline Falls dam removal and associated equipment and structures of the former hydroelectric power plant is the joint effort of the irrigation district, in cooperation with the Upper Deschutes Watershed Council.
Removal of the 120-foot-long, 5-foot-tall dam will improve ecological conditions of the river by allowing the river to flow naturally and restore the natural movement of sediment downstream. The project also includes site clean-up of left-behind contaminants.
Project costs are expected to exceed $2 million and are being financed by a settlement with Pacific Power.
Established in 1918, Central Oregon Irrigation District is a Municipal Corporation of the State of Oregon.
