Not illustrated. 1917 Excerpt: ...as given on Plate 68, was derived. The cofferdams built in May and June, 1906, entirely shut off the flow over the falls. Since the new plant commenced operation on February 9th, 1907, the flow at the Eastern Outlet has been through the power plant. The computed values of such flow have been furnished by the Manitoba Hydrographic Survey, and are available for the period since August, 1907. The energy being developed at the present Kenora Municipal Plant is being used for lighting, for water supply, and for manufacturing purposes. The plant was constructed for a total installation of six units. The preliminary installation comprised only three units, each unit consisting of four 40" Improved Samson runners on a horizontal shaft, direct connected to a 625 k. w., 2400 volt, 60 cycle, 3 phase generator. The installation also included two 120 volt, 1460 ampere, D. C. exciters, each connected to a 30" Twin Runner Horizontal Samson turbine. In March, 1913, a fourth unit manufactured by the Allis Chalmers Bullock Co. of similar capacity to the earlier units was installed. In the construction of the present power house and the establishment of gauges at the Plant, an assumed datum of 100.00 was used, which practically coincides with Kennedy's High Water Mark on Tunnel Island, elevation 102.54, Kennedy's datum. From February to April, 1913, meter measurements were taken at Section 7, Plate 28, by the Manitoba Hydrographic Survey. Readings of fore bay and tail race gauges, together with load carried and gate openings, were made while the meter measurements were in progress. The efficiency of the power plant from input to output was calculated for each discharge measurement. These efficiencies were then grouped according to load. The average load and efficien...
