DAILY STAGE OF THE OHIO RIVER FOR 1880.
No. 4.
KIRKWOOD’S SURVEY.
In 1865 the common council appointed a special commission to investigate and report upon the best method of obtaining an abundant supply of pure and wholesome water. The committee consisted of L. A. Harris, mayor; Thos. H. Weasner, president of council; D. T. Woodrow, Henry Pearce, and Henry Kessler, trustees of water-works, Geo. F. Davis, Wm. P. Wiltsee, and Chas. Brown, who succeeded R. B. Moore, members of council; and A. W. Gilbert, city engineer. They secured the services of the most eminent of engineers, John P. Kirkwood, of New York. His instructions were to ascertain the most economical and practical mode of supplying pure water, either from the gathering grounds by gravity, or by pumping from the Ohio River. No scheme was to be considered that would not provide at least thirty millions daily, with resources for future necessities. This limitation rejected Lick Run and Ross Run entering Millcreek; West Fork and East Branch of Millcreek, Duck Creek and Sycamore Creek entering Little Miami River. Those that presented fair prospects for the collection of water as regards quantity were:
