average 2080 gpd/ft with a range of200 - 5500 gpd/ft. Laramie Fox Hills wells will produce from 40 - 240 acre-feet per year per well at a rate typically of 100 - 200 gallons per minute. Transmissivities in the Laramie Fox Hills fOnTIation average 370 gpd/ft with a range of200 - 600 gpd/ft. Current 'Vater Rights and Water Sources Table E-2 describes the current allocation of water rights for groundwater resources within the District's boundaries. Table E-2 - ECcVWSD Water Rights (within District) I Classification Aquifer Source Annual Appropriation (ac-ft/yr) ~utary Cherry Creek Alluvium \1) 0 Nontributary Dawson 129 Denver 0 Arapahoe 4,827 Laramie-Fox Hills 3,219 Total 8,175 ( I) = does not include any lawn return flow development Currently, the District has developed approximately 7,455 acre-feet per year (92%) of the adjudicated non-tributary groundwater rights within the District boundaries. The District will develop six additional pairs of wells in the Arapahoe and Laramie Fox Hills formations to fully develop its adjudicated water rights within District boundaries. In addition to these non-tributary groundwater resources, the District has developed other non- tributary groundwater supplies to help meet its water demands. These include a lease of 4,000 acre-feet per year of Arapahoe aquifer water on State Land Board holdings to the east of Aurora Reservoir. This lease runs through 2032 and requires the District to develop all facilities and to pay $44/acre-foot per year for water delivered from the State Land Board. At this time, the District has developed six wells (Rangeview I) that are pumped into Aurora Reservoir as an exchange for potable water deliveries made through interconnections with the City of Aurora's water distribution system. This short-term exchange is scheduled to expire in May.2003. The exchange has produced approximately 1600 acre-feet per year of additional water supply at a cost of $0.59/1 000 gallons of delivered water. The capital and operating costs of the State Land Board wells are borne by the District. These State Land Board Arapahoe-formation wells produce between 150 and 200 gallons per minute with an annual production of approximately 200 acre-feet per well. An additional eleven wells are to be drilled in 200 I and 2002 (Rangeview II) and a transmission line constructed to deliver potable water directly to the District. These eleven wells will produce an additional 2,400 acre-feet per year. The District has rights to 756 acre-feet of South Platte River water as a part of previous settlements with Denver Water and 15 acre-feet of water purchased near Antero Reservoir for $10,000 per acre-foot. At this time, the District has no direct method for taking delivery of this \vater but is planning an exchange to Cherry Creek alluvial wells or through an interconnection \vith the Denver Water system at Willows Water District.
