All water not drawnout through the pipes will be stored in the reservoir, and it is antici-pated that during the coming spring a large amount of water will beso stored in the reservoir for use during the coming drier season. The pool below the dam, into which the waste water is to bebrought from the gate-chamber, has been nearly completed. A large amount of excavation has been done for the preparationof the waste channel or spillway at the western end of the dam,through which the water may be wasted in case there is an overflowfrom the reservoir, after the completion of the dam.
