Show water. When constructed the reservoir had a greater depth, but of late years sedimentary deposits have covered much of the bottom, reducing: the capacity fully one-third. Were the walls of the dam as high as originally planned, tho reservoir could be made to serve to some purpose in a period of flood, as its storage capacity would be equal to a good sized lake, but a reservoir capable of materially checking Ogden river this spring would have to be valley-wide and canyon-deep. An engineer predicts that the river will be flowing approximately approximate-ly 4,500 second-feet in high water. As a cubic foot of water equals 7.48 gallons and there are 3,600 seconds in each hour of time, multiplying mul-tiplying 4,500 by 3,600 gives .121,176,000 gallons as tho probable flow of Ogden river each hour during, the flood period. Now Ogden City has two reservoirs, one of which holds 6,500,000 and the other 13,500,-000 13,500,-000 gallons, or a combined capacity of 20,000.000 gallons. Ten minutes min-utes flow of the river in flood would overflow these storage ponds which are large enough to meet the water consumption of the entire city for a period of about three weeks. That offers a faint idea of the ! great volume of water which for days comes down from the water-j water-j shed to the east of Ogden. I Great Salt Lake, with its wide expanse, is none too great for the mighty rush which is to start soon and continue well into the summer. The lake will rise a foot or more, although each foot must ! push the shore line out over miles of country which ha3 not been I inundated in thirty years. WHEN THE FLOODS START. There is enough snow in the mountains of the drainage basin vhich forms Ogden River, to set the canyon stream on a rampage . vhen the thaw of early spring comes ; and this snow is being added to until there seems to be no limit, and no one can even approximate :he amount of moisture being stored, or how much water will be released re-leased when the warm days come. It has been suggested that the Utah Light & Railway company might drain the large reservoir in Ogden canyon to the minimum requirements of the power plant and keep the gates open until the crest of the spring freshets shall be reached, when the storage of part of the flood water might save the lowlands around Ogden from a disastrous overflow. But that is not feasible, as the reservoir has become a shallow pond, containing a depth of less than six feet of |
