Prc,j�ct 11 -1 .2 <br /> May 25, 1972 <br /> III - SITE CONDITIONS <br /> Dra i nage <br /> • The terrain of. the disposal site and vicinity slopes gently to the <br /> southwest at a rate of approximately 6 feet per mile. The south 1/3 of rhe <br /> site is separated from the remainder of the quarter-section parcel by the south <br /> branch of South Littlejohn Creek, which traverses the site in a southwesterly <br /> alignment. Runoff from Austin Road and areas immediately east of the site is <br /> intercepted in roadside ditches and conducted along and under the roadway <br /> to a 4ift. deep ditch along the south property line which empties into Little- <br /> john Creek near the southwest-corner of the site. <br /> Littlejohn Creek channel was excavated and cleared as part of the <br /> Army Corps of Engineers' Farmington Project, which also included Farmington Dam <br /> and the Duck Creek diversion channel located east of the site. Flow in <br /> Littlejohn Creek results primarily from controlled discharges from Farmington <br /> Reservoir approximately 15 miles east of the site. Additional flow is <br /> divertod into Littlejohn Creek from Duck Creek through the Duci< Cr`ei; diversion <br /> channel , approximately 11 miles east of the site. Reservoir outflows are <br /> controlled to not exceed the non-damage channel capacity of Littlejohn Creek <br /> downstream from the diversion channel less any flow diverted to Duck Creek' . <br /> Approximately 9 miles east of the site, Littlejohn Creek splits to fore: North <br /> Littlejohn Creek and' South Littlejohn Creek. A division. of flow structure at <br /> this location limits flow into North Littlejohn Creek to 250 CFS. Th,✓ rated <br /> ca P city of South Littlejohn Creek at this point is 1750 GFS.
