The Bureau of Reclamation will begin collecting concrete core samples next month in Lake Tahoe Dam as part of the Lake Tahoe Dam Rehabilitation Study. While the dam is currently safe to operate, the study, funded by the Bipartisan Infrastructure Law, is being conducted to evaluate alternatives for needed repairs.  Restoration repairs are needed to address deterioration in the 115-year-old dam structure … Gate operations have also been affected as gates have become temporarily immobile or unable to close due to the concrete deterioration.
