TRUCKEE, Calif. – Under the Bureau of Reclamation’s Safety of Dams Program, Stampede Dam and dike structures are being raised by 11.5 feet to address dam safety concerns related to large flood events. In addition, two small dikes will be constructed near the south end of the reservoir to fill low-lying areas of the reservoir rim. The spillway crest structure will be reconstructed to control outflows during large flood events to the current spillway discharge capacity of approximately 3,000 cubic feet per second. Completed in 1970, Stampede Dam is a zoned earthfill embankment dam located approximately 11 miles northeast of Truckee, California, in Sierra County.
The construction contract for this work was awarded in May 2016 to NW Construction Incorporated (NW). NW will mobilize to Stampede Dam in August 2016 to begin preliminary construction activities. Preliminary construction activities to be completed during 2016 include improvement and surfacing of the Dog Valley Road detour route (from Hobart Mills to the Stampede Boat Ramp turnoff); timber clearing; construction of two small dikes; and some miscellaneous work to prepare for the 2017 construction season. There will be no road closures in 2016; however, some traffic control may be in place for safety purposes. Please look for road guards and signage as you drive through the area.
Beginning in April 2017, the eastern section of Dog Valley Road, which crosses the dam and dike, will be closed to allow for construction on the main dam structure. Access to the reservoir will be available using the posted detour routes. A hyperlink to the temporary detour routes which shows the closed section of Dog Valley Road is found at http://www.usbr.gov/mp/sod/projects/stampede/index.html.
The Boat Ramp and Logger Campground will remain open during construction. The Emigrant Group Campground will be closed from April 2017 to October 2017 for construction activities.
The website will be revised periodically with updated information as the construction project progresses. For information, please visit http://www.usbr.gov/mp/sod/projects/stampede/index.html.
