. . .. POTENTIAL PROJECTS NORTH CANADIAN RIVER BASIN Palo Duro Project General -- Palo Duro Project is on Palo Duro Creek, a tributary of the North Canadian River, in Hansford County, Texas. It would provide for the irriea- tion of about 2,200 acres of valley lands and would also provide for recrea. tion and some inoidental flood control. Serving of irrigation water to the project landS could be accomplished either by a single gravity flow canal or by a series of pump canals along the stre~. Initial costs of either delivery system would be about the same, but the pump canal system would demand greater operation and maintenance costs. Project lrJorks Th€ project would consist of a dam and reservoir, about 15 miles of main canal, ~,d acout 2,200 acres of irrigable lands. The dam site is in Sections 64 and 73 of H & T RR Co., Survey Block No. 45. It controls a drainage area of 552 square miles, of which 236 square miles are only partially contributing. The dam would consist of a rolled earth embankment about 1,450 feet long and about 86 feet high above stream bed. Following is an area capacity table of the reservoir site.

It would serve 2,200 acres of land and would have an initial capacity of 45 cfs and a terminal capacity of 17 cfs. Laterals are required for only 300 acres of the project area, the remainder being served from the main canal. 36
