(which, per the well permit, had been located in one of the gravel pits on the property) had previously been disconnected and the pump had been pulled. Headley Wells 3993-F and 5709-F were last used in October 2003, and power to each well was disconnected in April 2004. Each well had been equipped with a flow meter in 1993. Prior to that time the only available estimates of well pumping were estimates included as part of annually approved substitute water supply plans submitted by Groundwater Appropriators of the South Platte, Inc. ("GASP"). GASP showed no records of pumping of Headley Wells 5709-F and 10794-F prior to 1993. c) Gravel mining operations on the Headley Farm, which had been discontinued by the time Pinneo acquired the property, left Gravel Pits Nos. 1 and 2 as a single pond. No exposed ground water remains in Gravel Pit No. 4a. A small amount of exposed ground water remains in Gravel Pit Nos. 1 and 2. d) In substitute water supply plans approved annually since 2004 by the State Engineer pursuant to C.R.S. § 37-92-308(4), for the replacement of out-of- priority depletions associated with use of the Pinneo Wells, Pinneo has continued to account for augmentation obligations created by virtue of any past and continued uses on the Headley Farm and all the resulting out-of- priority depletions therefrom to the South Platte River. The recharge credits available from Pinneo's interest in the Headley :Recharge Project for augmentation of the Pinneo Feedlot Wells are therefore limited to those credits that exceed such prior augmentation obligations. The midpoint of accretions from the Headley Recharge Project reaches the South Platte River at a location in the NW 1/4 SW 1/4 of Section 33, Township 5 North, Range 55 West, 6a' P.M., Morgan County, Colorado. Based on the midpoint of accretions, 49% of the accretions affect the South Platte River upstream of the inlet to the North Sterling Canal and 51% of the accretions affect the river downstream of the inlet to the North Sterling Canal. 2) Jackson Lake Rights: a) Pinneo purchased the Jackson Lake Rights along with a farm under the Lower Platte and Beaver Canal in 1991. The Jackson Lake Rights were historically used on the Lower Platte and Beaver Canal farm until the farm was sold in 2003. b) The water rights represented by shares in Jackson Lake Reservoir and Irrigation Company are a senior and sought-after supplemental irrigation supply that serves multiple ditch systems in the area. c) Because not all of the water released under the Jackson Lake Rights was historically consumed during irrigation, Pinneo's future use of such water for augmentation and replacement purposes must account for historical return 13 of 33
