A dry season in 1929 resulted in low water level in 1930 and it became necessary to find additional sources of water in order to maintain the amount of power required for construction. The outlet of

and fuses. Rated at 2,000 kV⋅A, these transformers stepped the voltage up to 26,400 volts for transmission to Island Falls. There, a sub-station stepped the current down to 600 volts for two motor-generator sets which supplied current for the electric locomotives used in hauling earth, concrete

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

Work on the temporary power plant was started on
October 4, 1928. Its operation began on March 20, 1929, and continued without interruption until No. 1 Unit at Island Falls took up the load on June 5, 1930. Subsequently, the Spruce Falls plant was dismantled, and, under very difficult freighting

The Spruce Falls temporary powerhouse was a frame building on the shore of
Sisipuk Lake. It contained two small generating units and complementary equipment. These two 930 kW (1,250 hp) vertical-type turbines, with propeller-type runners, were directly connected to 1,000 kV⋅A

By utilizing the natural fall of 7.6 metres (25 ft) at Spruce Falls in addition to a 4.6-metre-high (15 ft) timber dam which impounded a small forebay, a head of 12 metres (40 ft) was developed. Water from the head pond was conveyed to generator turbines by two

1.8 metres (6 ft) in order to furnish enough power to complete the construction at Island Falls. After construction, the outlet was replaced by a faced, rock-filled, timber-crib weir, thus restoring
Chicken Lake to its former elevation.
