What are construction crews doing at 2 a.m. at the Calaveras Dam? They are working in the pre-dawn hours to mix and place concrete for the new spillway. Over 40,000 cubic yards of concrete will be placed into the new 1550 ft concrete spillway for the Calaveras Dam Replacement Project. Crews have to work in the early hours to ensure the concrete maintains a precise temperature to cure and reach its optimum strength. We are approximately 30% complete with the concrete spillway work.

Crews work early hours placing concrete on the new spillway. All concrete is mixed on-site at our batch plant reducing truck deliveries on public roads.
