Canal Capacity Studies Main Canal Columbia Basin Project
Additional tests were made during 1965, 1966, and 1967 on the Long Lake Reach of the Main Canal, Columbia Basin Project, to determine the hydraulic properties of the canal and the effect of aquatic growths during these years. Test methods and observation locations were the same as the 1963-64 studies. Filamentous algae growth was light to moderate and generally much below that observed during prior seasons. Fresh water sponge infestation was reported to be increasing. Flow resistance improvement after treatment of the canal with copper sulfate was not as great as had been anticipated. Two weeks after treatment, flow resistance returned to about pretreatment values. (Author)
