Dallas Augments Its Water Supply.
With nearly half a billion gallons of water in the new White Rock reservoir and with Turtle Creek, Bachman’s and Record Crossing reservoirs filled to overflowing, Dallas, Tex., is declared to be in better shape as to water supply than in several months. Water Commissioner Nelmes estimated the city’s water supply as follows, having heard of a rise of only one inch at White Rock at the time he gave his figures: Bachman’s Dam, 750,000,000 gallons; Turtle Creek reservoir, 100,000,000 gallons; Record Crossing, 400,000,000 gallons; White Rock, 350,000,000 gallons.; total, 1, 600,000,000 gallons. At the stage at which White Rock is standing now, it is estimated that each additional inch rise means 15,000,000 to 20,000,000 gallons, so that the total supply now impounded by the city’s reservoirs may be said to exceed 1,500,000,000 gallons. At the rate at which Dallas is using water at present, about 9,000,000 gallons per clay, this supply would last 160 days, allowing considerable part of the supply to evaporate. But it is pointed out by Commissioner Nelms that for two or three months the city will not have to draw upon its impounded water supply at all, but can simply pump as much water into Turtle Creek from Record Crossing each day as is being pumped out of Turtle Creek into the city mains. He thinks the Elm Fork of the river will flow enough water for several months to allow 9,000,000 gallons to he drawn out each day without reducing Record Crossing below the level of the dam. According to this view, Dallas will have plenty of water until the end of the present year even without rain. Then Mr. Nelms sees other things coming that will add still more to Dallas’ safety from the one-time fear of water famines. If floods ever stop coming down the Elm Fork of the Trinity, California Crossing will be dammed in and ready to hold about 300,000,000 gallons, and shortly after that the Carrollton clam will be ready to hold its 450,000,000 gallons. In addition, the Trinity Sands well at Bachman’s is expected in within 20 days, and it will flow 1,000,000 gallons per day if it meets expectations. It is now 2,050 feet deep and the depth usually required around Dallas to strike the Trinity Sands is about 2.300 feet. The artesian well to the Trinity Sands, which is being dug in Fair Park, has been sunk to a depth of 1,250 to 1,300 feet. The third well in Oak Cliff is now about 1,900 feet and will be brought in in about two or three months.
