This was considered the most economical arrangement because when the power plantwas originally installed various considerations dictatedthe wisdom of placing it about 1,600 ft. back fromthe Big Sandy, on an elevation well above high-watermark in the flood season. The river rises normallyabout 30 ft. each spring, the flood occurring in Marchor earlier. The record high water was that of 1913,when the rise was 40 ft. No spraying devices wereused in connection with the pond in the original plant. Shortly after the plant was taken over, two 1, turbines were put in, one being a high-. Pumping Plant on the Bank of the Big Sandy River,with Power Plant in Distance pressure and the other a low-pressure machine. Aspray system was installed in the pond, and an exten-sion to the boiler house was built to house sevenadditional B. & W. boilers, three of which were usedto replace the old Berry boilers. As soon as this equipment was installed the demandon the station increased so rapidly that it was decidedto install a 7,500-kw. General Electric turbine witha surface condenser. When this unit was operated inconnection with the spray pond, the load continuingrapidly to increase, it was found that the capacity ofthe pond had been exceeded. Further, an additional generating unit was foundnecessary, and a 12,500-kva. (10,000-kw. at 80 per centpower factor) General Electric turbine was made absolutely necessary the increase in facil-ities for supplying circulating water and the decisionwas leached to install an electrically-driven pumpin
