The most northerly of the two facilities is on the East Toba River and is the largest run-of-river project in B.C. It has a 30.7 m3/s design flow and 581 m gross head. About 17 km southwest is the facility on Montrose Creek, which has a 22.8 m3/s design flow and 466 m gross head.

Knight Piésold Consulting Engineers originally identified the sites and the idea of the combined projects. They obtained the permits for the owners, Toba Montrose General Partnership, and then were hired by Kiewit to do the detailed design under an EPC (engineering-procurement-construction) contract.
