In the case of TWSD, the legal ability to pump the ground water is not the limiting factor in their supply. However it is the pumping capacity that is the limit. For example, to obtain the original capacity of Well No. 1 more than one well is needed and the required well spacing makes the Lambert Ranch ideal. <br />Meadows Ditch Surface Water Rights <br />Issue: What is the rough distance to the nearest surface wa ter alternative? The Meadows Ditch on Indian Creek is the closest surface water rights to TWSD. The ditch is approximate 0.4 miles downstream from the northern boundary of TWSD. The surface water rights are intermittent and seasonal water rights that would require storage to create a dependable year round supply . TWSD does not currently have the storage facilities or water treatment facilities to treat raw surface water. <br />Historic and Current Water Uses of Lambert Ranch <br />Issue: Current and Past u se of Lambert Ranch. To the best of our knowledge Lambert ranch was operated historically as a ranch with irrigated pasture. The pasture was originally irrigated with surface water from Meadows Ditch. The pasture land was not irrigated with Denver Basin ground water which is what TWSD is proposing to purchase. Therefore, this project does not include any dry up of historically irrigat ed lands . <br />Schedule <br />Issue: What is the timing for the proposed Lamber t Ranch well to be constructed? The District h as $500,000 in the 2011 budget to drill Well No. 4 , a new well to be located on the easements included in the pending Lambert Ranch Water Rights purchase. The new well would put the Lambert Ranch Water Rights to beneficial use, would increase the dependab ility o f the District’s physical supply, and would be located to reduce interference with the yield from the District’s two operational wells. The District’s adopted 2011 budget which shows the anticipated well construction budget was attached to the Loan Feasibility Study (April 4, 2011). The District plans to purchase the water rights, design a new well and associated infrastructure, and construct the well and infrastructure within the next two years.
