Box Canyon Dam, Gravity dam near Mount Shasta, California.
Box Canyon Dam extends 1,100 feet in length and rises 209 feet high on the Upper Sacramento River, forming Lake Siskiyou in the eastern Trinity Mountains.
The construction of Box Canyon Dam began after California approved funding studies in 1959, with the main structure completed in 1970 and the powerhouse added in 1984.
The Lake Siskiyou Trail system incorporates the dam structure into its path network, connecting local outdoor recreation areas with the surrounding Shasta-Trinity National Forest.
The dam maintains a storage capacity of 26,000 acre-feet of water and generates hydroelectric power while providing flood control for communities in Siskiyou County.
The dam's spillway manages water discharge rates up to 56,000 cubic feet per second through the narrow canyon leading toward the town of Mount Shasta.
