Spruce Falls was the local name for a small waterfall where the Swan River empties into Sisipuk Lake in north-eastern Saskatchewan, near the Manitoba border.

[1] A large amount of power is required for construction purposes on a job the size of the Island Falls development.

As steam and gasoline units could be used only to a minor extent, owing to the high cost of transporting fuel, the only alternative was to find a site where hydroelectric energy could be generated.

These two 930 kW (1,250 hp) vertical-type turbines, with propeller-type runners, were directly connected to 1,000 kV⋅A generators delivering power at 600 volts, 3 phase, 60 cycles to a bank of transformers.

During the period of operation this plant supplied 4,698,000 kWh of electrical energy for construction purposes, at an average cost of 4.35 cents per kilowatt-hour.
