LSPWCD <br />was formed in 1964 under the Water Conservancy District Act of 1937. The district provides <br />augmentation for 62 wells in Sedgwick County. These wells operate under The Julesburg <br />Recharge Project (JRP) which has been in operation since 1990. The original JRP rechazge facility <br />was created as a recharge demonstration project. It was cazried out in association with the <br />Colorado Division of Water Resources and has proven to be a successful venture. In 1993 the JRP <br />was set up as a Water Activities Enterprise under LSPWCD. This created a program where <br />participating well users pay for all costs associated with the rechazge project and well augmentation <br />while LSPWCD provides water and financial accounting for the project and helps to manage the <br />administration. <br />LSPWCD has recently obtained a court decreed augmentation plan (Case No. 02-CW-320) this <br />month. Well users under the LSPWCD operated under a Colorado State Engineer approved <br />substitute water supply plan during the 2006 water yeaz. LSPWCD fully augmented out-of-priority <br />depletions to the river as required by the state and division engineer. The replacement supplies <br />consisted of the generating and leasing of recharge accretion credits in addition to the generating <br />and leasing of augmentation well water. <br />I have completed all of the accounting necessary for the LSPWCD operations for the 2006 water <br />year. This involved the use of groundwater modeling using the AWAS model (Glover method) <br />developed by the IDS group at CSU to compute lagged well depletions and recharge accretions at <br />the river. Electrical power records and flow meter data were collected for the wells by district <br />personnel, and records provided by the water commissioner were utilized to quantify rechazge site <br />inflows. <br />
