Kattenburg Pit SWSP September 26, 2024 Page 5 of 11 X = 2,300 ft* X = 1,200 ft* W = 3X0ft W = 3J00ft *Need to adjust the distance from the Fraser River to the structure based on the as-built location. Assuming a call year-round affecting this reach of the Fraser River, the lagged stream depletions are equal to the augmentation requirement that require replacement to prevent injury to senior water rights. Typically, the call on the Fraser River emanates far downstream on the Colorado River at the Shoshone Power Plant and/or at the Grand Valley Canal, but in certain limited circumstances the Colorado Water Conservation Board ("CWCB") can place a call for its instream flow right ("ISF") on the Fraser River located between the confluence with Crooked Creek and the confluence with the Colorado River and/or its instream flow right on the Colorado River located between the Windy Gap point of diversion and the confluence with the Williams Fork River. Replacement As identified in the SWSP request, United has entered into a short-term contract (copy of lease attached) with Middle Park Water Conservancy District ("MPWCD") for up to 4 acre-feet of replacement water that will primarily be released from either Wolford Mountain Reservoir or Windy Gap Reservoir. It should be noted that MPWCD's Windy Gap water is actually stored and released out of Granby Reservoir. When releases are made from Wolford Mountain Reservoir, an estimated transit loss at the rate of 0.25% per mile will be assessed. MPWCD will also make water in Sunset Ridge Pond available to United in the event CWCB has placed a call on its ISF on the Fraser River. Sunset Ridge Pond is located adjacent to the Fraser River near Tabernash approximately 9 miles upstream of the Kattenburg Pit. When releases are made from Sunset Ridge Pond, an estimated transit loss at the rate of 0.25% per mile will be assessed.
