Design of reservoir and dam on Hinkson Greek for Columbia, Mo. water supply
Metadata[+] Show full item record
"The proposed reservoir and dam lies on Hinkson Creek between Ashland Road and the Quarry Road about 3/4 of a mile S.E. of Columbia, Mo. in Sec. 19 of R. 15 W. Twp. 48 N. A topographic survey of the site was made with transit and stadia and a cross section of the valley was taken by the same method. No surroundings for bed rock were necessary as it was easily estimated as to the slope for such a short distance. The required data as to the water supply for said reservoir was taken from the daily gage readings of H. G. Hunter and C. F. Phillips for 1909; a copy of which can be found in their thesis for 1909; and the daily gage readings of H. Horan and R. Hodson for 1911. These gage readings were taken on both the Hinkson and Grindstone Creeks and by the combined results obtained from the two sets the discharge of the Hinkson at the dam site was determined. Tncorporated in this investigation is the topographic map of the reservoir site, hydrographs and rating curves of both creeks and sections and elevations of a rough masonry dam 900 ft. long and 35 ft. high. Following this are the estimates and costs tabulated. "--Introduction.
