Alternative Agricultural Water Transfer Methods -Grant Application Form <br />January 2008 <br />applications or development of engineering reports for support of the change case applications. <br />• Method or procedure that will be used or followed to accomplish the task and ident? who will <br />undertake the task.' <br />Methods and procedures used in the Task will be as follows: <br />? Historical consumptive use analyses: Existing ditchwide and parcel based historical use <br />analyses will be reviewed. To the extent possible, existing studies and analyses will be used <br />in order to avoid duplication of efforts. For budgeting purposes, however,it is assumed <br />that it will be necessary to conduct two historical use analyses on irrigated lands that are <br />the subject of the selected water transfer projects. StateCU will be used to estimate <br />historical consumptive use and on-farm return flows. AwAS will be the primary tools <br />used to conduct analyses on the lagging of return flows. Brown and Caldwell will conduct <br />this analysis and will work with DU and the par?cipating land water owner. <br />• Consumptive use data for wetlands: The first step in this task will be to survey available <br />applicable data concerning consumptive use of wetlands populated by wetland species <br />occurring in the South Platte River basin. The results of this survey will be used to <br />develop estimates of wetland consumptive use or to develop crop coefficients that can be <br />incorporated into programs such as StateCU. Consumptive use levels under various <br />hydrologic conditions will be developed. Brown and Caldwell will complete this subtask. <br />? Quantification of potential recharge credits: The volume of recharge credits available for <br />use by municipalities and others will be based on the potential supply of water to each <br />wetland project minus the consumptive use of the wetland. The tinting of availability of <br />recharge credits to the South Platte River will be estimated using ACAS. Brown and <br />Caldwell will complete this subtask. <br />• Economic data: Business and economic data obtained and?or developed in earlier tasks <br />will be used to help establish costs of the water supply required for the wetland recharge <br />area and the economic benefits to the agricultural producer supplying the water. Dr. <br />James Pritchett and Brown and Caldwell will participate in this task. <br />• Legal guidance: Guidance will be provided regarding potential legal issues associated with <br />specific methods of alternative agricultural water transfer methods for each project. Lind, <br />Lawrence, and Ottenhoff will provide this guidance. <br />• Administrative and operational guidance: Guidance will be developed concerning water <br />accounting, methods of water measurement, dry-up, and other administrative and <br />operational issues associated with each project. Brown and Caldwell will lead this effort <br />and will be assisted by Lind, Lawrence, and Ottenhoff; DU; and the Colorado Corn <br />Growers. <br />? Description of the major deliverables/products that will be produced upon successful completion of <br />the task: <br />The data and analysis produced by this task will be provided to DU in a series of technical <br />memoranda or other suitable forms to allow DU to begin implementafion of the projects. These <br />technical memoranda and other documents can be included in the Summary Report to C?X1CB <br />26
