Excerpt from The Irrigation Age, Vol. 28: November, 1912Again, a diversion dam in connection with the canal head gates must always be able to reject the ¿oating trash and sand at the intake and discharge them through the dam. Moreover, the pond above the diversion dam must neither be allowed to fill up, nor must the water level be lowered below the service point. Yet it must at the same time be controlled against sudden rises which would over top the head gates.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
