Document Description
The Project involves removal of between 2.1 mcy and 4.4 mcy of sediment from BTR and depositing the sediment in Maple Canyon SPS. The purpose of the Project is to maintain the capacity of the reservoir and protect the operability of the outlet works, which are necessary to protect life and property by attenuating storm water flow peaks and to capture locally generated water to support the region’s water supply. Other minor activities include: hydroblasting to flush a stilling well on the dam crest; repair of the hydraulic sluicegate; access road paving and repair of the culvert crossing; slope protection measures adjacent to the spillway; rehabilitating the northern access ramp to safely access the reservoir bottom; installing a boat dock at the dam face; and performing minor coring on existing dam riser and installing a slide gate to facilitate dewatering.
