Rothe <br /> <br />Introduction <br />Mildred Rothe is applying for a $353.482 loan to construct the Rothe Augmentation Plan, <br />consisting of 3 recharge wells, 2 augmentation wells, 3 separate pipelines, and 33 recharge sites. <br />The estimated total cost of the project is $392,758. Please see the attached project summary and <br />map, <br /> <br />Backaround <br />The Rothe Farm, located in Morgan and Weld Counties, consists of over 9000 acres. Irrigation <br />water is supplied by direct flow water rights, and by irrigation wells. <br /> <br />There are 17 junior wells on the Rothe Farm. The depletions from the pumping of these wells <br />must be replaced during times when there is a "call" on the river by a senior downstream water <br />right. GASP has successfully been used for the past 30 years to cover the depletions on these <br />wells. However, GASP operates on a year-to-year basis with no guarantee of continued <br />coverage, The current drought has brought to the foreground just how difficult it is to provide <br />adequate augmentation for well users. GASP has even indicated to its members that if the <br />drought continues, well pumping may be curtailed, <br /> <br />The Rothe Farm wants to construct a recharge system (the Rothe Augmentation Plan) to <br />generate augmentation water to be used to offset the depletions caused by 17 wells serving <br />3055 irrigated acres, By generating its own augmentation credits, the Farm can protect itself <br />from pOSSible curtailment and help GASP strengthen its coverage in the same area of the river. <br /> <br />Feasibility Studies <br />Brent Nation, P.E. of Nation Engineering Services, has completed the feasibility study. The report <br />includes an evaluation of alternatives available to generate an augmentation supply for the Rothe <br />Farm wells, <br />
