Black Canyon Dam
Constructed in 1924, this $1,500,000 concrete gravity dam has a 1,039 foot crest and a 183 foot structural height.
A 29 mile canal, along with lesser ditches, serves 58,250 acres of Boise and Payette valley farms. A power plant at Black Canyon Dam generates electricity for commercial use as well as for irrigation pumping. Farms far from early riverside canals benefit from this project.
Marker can be reached from Black Canyon Highway (State Highway 52 at milepost 38), 0.2 miles east of Old Dam Road.
