The Main Canal extends from Savage Rapids Dam westward on the south side of the Rogue River for 9.2 miles and has a diversion capacity of 100 cubic feet per second. At about mile 6, the canal divides, with one branch serving an area north of the river through the Northwest Unit pipeline. The Tokay Canal extends from the dam westward on the north side of the river to a few miles beyond Grants Pass. This canal has a total length of 12.5 miles and a diversion capacity of 40 cubic feet per second. Other highline canals, including one on each side of the river eastward to Evans Creek, increase the total canal length to about 67 miles.
Laterals deliver the water to project lands.
Pursuant to a report prepared in 1974, work was authorized and completed on anadromous fish passage facilities at Savage Rapids Dam. Fishways on the south side of the river were repaired and modified. After the 1978 irrigation season, the existing north fish ladder was removed, and a new fishway constructed. This fishway uses turbine discharge for attraction flow, and accommodates a large range of streamflow variations without adjustment. The project is operated and maintained by the Grants Pass Irrigation District.
