Document Description
The Lost Creek Weir Repair Project is limited to the repair of a concrete weir used to measure flows below the Lost Creek Hydroelectric Plant. Concrete will be used to repair and seal leaks located on the western weir abutment. To perform the work, stream flows will be reduced from 15 to 8 cubic feet per second for a period of up to 48 hours, to allow flow to be diverted and channeled along the right side of the creek. A cofferdam will be constructed around the western weir abutment, and approximately 2-4 cubic yards of wet concrete will be added to seal leaks. Heavy equipment (tract excavator) will be used on the western bank of Lost Creek to remove gravel/boulders from the weir abutment area and to deliver concrete to the western abutment.
