Hyatt Dam in Oregon, US, is to be modified to limit the risk of internal erosion in the structure, with Suulutaaq, Inc recently awarded a $4.4 million contract for the work by the US Bureau of Reclamation.

Work under this contract involves excavating portions of the existing dam embankment and foundation, reconstructing the dam embankment, furnishing and installing toe drain pipes and concrete inspections wells, constructing a concrete spillway stilling basin and headwall retaining structure, and extending current piezometers. Construction activity will begin in early June 2017 and be completed by the end of November 2017.

“Reclamation has worked diligently on the safety and function of our dams,” commented Reclamation’s Acting Commissioner Alan Mikkelsen. “This work will enable Hyatt Dam to continue to provide irrigation and recreation to the area for many years to come.”

Hyatt Dam was constructed in 1923 by the Talent Irrigation District (TID) for water storage. In 1960, USBR modified the dam, constructing fish screens and recreation facilities as a part of the Talent Division. USBR owns the dam, but it is operated by TID.
