LSPWCD was formed in 1964 under the Water Conservancy District Act of 1937. The district • provides augmentation for 62 wells in Sedgwick County. These wells operate under The Julesburg Recharge Project(JRP)which has been in operation since 1990. The original JRP recharge facility was created as a recharge demonstration project. It was carried out in association with the Colorado Division of Water Resources and has proven to be a successful venture. In 1993 the JRP was set up as a Water Activities Enterprise under LSPWCD. This created a program where participating well users pay for all costs associated with the recharge project and well augmentation while LSPWCD provides water and financial accounting for the project and helps to manage the administration. Well users under the operation of the LSPWCD plan must attain a permanent court approved augmentation plan by 2007. LSPWCD has filed for a permanent Augmentation Plan (Case No. 02- CW-320) and is set for a ten day trial in Water Division 1 District Water Court beginning April 16, 2007. Well users under the LSPWCD operated under Colorado State Engineer approved substitute water supply plans during the 2003 and 2004 water years. LSPWCD fully augmented out-of- priority depletions to the river as required by the state and division engineer. The replacement supplies consisted of the generating and leasing of recharge accretion credits in addition to the generating and leasing of augmentation well water. I have completed all of the accounting necessary for the LSPWCD operations for the 2003 and 2004 water years. This involved the use of groundwater modeling (SDFView) to compute the lagged well depletions and recharge accretions at the river. Acreage reports, electrical power records and flow meter data were collected for the wells by district personnel, and records provided by the water commissioner were utilized to quantify recharge site inflows. ��0g0UIli pi NIy k1V4)
