Stampede Dam (LBAO)

Stampede Dam on the Little Truckee RiverStampede Dam is located on the Little Truckee River, approximately 10 miles northeast of Truckee, California.

Background: Reclamation is raising the dam and dike structures 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 limit outflows during large floods to the current spillway discharge capacity.

The construction contract for this work was awarded in May 2016 to NW Construction Incorporated (NW) for $21.8 million. Construction activities will begin in 2016 and extend through September 2018.

Current Status:  NW will mobilize to Stampede Dam in August 2016 to begin preliminary construction activities. Preliminary construction activities to be completed in the 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.

2017 Outlook:  Beginning in April 2017, the eastern section of Dog Valley Road which crosses the dam and dike will be closed to allow for construction.  Access to the reservoir will be available using the detour route.  A hyperlink to the temporary detour route which shows the closed section of Dog Valley Road is found below.

The Boat Ramp and Logger Campground will remain open during construction and the Emigrant Group Campground will be closed from April 2017 to October 2017.
