With more than 32 second-feet of water entering the intake at the headgates on Asotin creek to be emptied into Clarkston and Asotin reservoirs and surplus water flowing over the dam, an adequate supply is anticipated for irrigation unless unusual conditions develop, according to Grover Beckman, Lewiston, divisional W. W. P. Co. manager. In case of shortage to the Asotin creek supply, emergency pumps are in readiness.
Due to abundant snow on the upper tributaries of Asotin creek, the supply is reported to be greater than usual. Through melting snowdrifts in the watersheds of Asotin creek during the last three months, and the additional rainfall, the supply is reported greater than any previous year. Only a slight decrease is noted in the daily water flow from Asotin creek, despite high temperatures at intervals the last three weeks.
Despite the heavy drain of the system for irrigation and sprinkling, the city reservoir is full. Water requirements are reported the heaviest in July and August.
The Washington Water Power company maintains a patrol on Asotin creek and its watersheds to see that no contaminating material is permitted to accumulate.
The sterilization plant at the headgates is kept to constant operation and the water is tested at taps in Clarkston Heights, Asotin and Clarkston.
The Washington Water Power company cleanses the city reservoir south of the city of silt and debris every year. The reservoir improvement program the last two years has involved the installation of a valve at the base of the reservoir, concrete finishings and other improvements.
The auxiliary pump at the north Clarkston sub-station on the Snake river has been operating for irrigation purposes.
