Two augmentation stations from Meadows West Reservoir, as shown on the attached map will pump water to Little Dry Creek then from there to the South Platte River below the Meadow Island No. 1 headgate. The two stations are: the Northwest Station to Little Dry Creek located at 40.1095270 N, 104.834691 W about 4 miles from the confluence with the South Platte River and the Southeast Station to Little Dry Creek located at 40.102871 N, 104.8295469 W about 4.5 miles from the confluence with the South Platte River. Transit losses from a point directly east of the reservoir on the South Platte River will be 0.25 percent winter transit loss per mile. The applicant shall obtain prior permission from the District 2 Water Commissioner when making releases from this reservoir. Credit will not be given to any releases not measured and recorded to the satisfaction of the District 2 Water Commissioner or Division Engineer. During times a winter call on the reach of the South Platte (i.e., the Milton Reservoir storage right at the Platte Valley Canal Headgate), replacement supplies will be from L.G.

The wells are currently permitted for industrial, commercial and augmentation use and are allowed a combined average annual withdrawal of 73.1 acre -feet and a pumping rate of 150 gpm. The wells are further described in the following Table F. The Applicant's accounting includes the 2% relinquishment requirement for the nontributary Laramie -Fox Hills water. TABLE F — L.G.
