decision support system, South Platte Mapping and Analysis Program (SPMAP). Recommend a <br />method and develop up to three (3) locally calibrated crop coefficients for use with the Blaney- <br />Criddle methodology within the SPDSS study area. Using calibrated crop coefficients, estimate <br />the potential consumptive use for up to four (4) common crops grown at the key climate stations <br />identified in Task 53. <br />Approach: <br />59.1 Gather and review appropriate data and literature from previous lysimeter studies <br />representing the SPDSS study area and use results to develop Blaney-Criddle crop <br />coefficients used by StateCU to calculate consumptive use. <br />59.2 Gather and review appropriate data and literature from previous studies that developed <br />Blaney-Criddle crop coefficients to represent local conditions and studies of high altitude <br />Blaney-Criddle crop coefficients. <br />59.3 Review CSU's Kimberly-Penman methodology and determine its appropriateness for use <br />in the calibration of Blaney-Criddle crop coefficients by comparing results to lysimeter <br />studies. <br />59.4 Summarize, review, and recommend methodology for the development of locally <br />calibrated crop coefficients by geographic regions. Develop locally calibrated crop <br />coefficients using the recommended methodology and estimate potential crop <br />consumptive use for up to four (4) common crops at each of the key climate stations <br />identified in Task 53 during the SPDSS study period. The crops may vary depending on <br />the primary crops grown in the climate station geographic region. <br />Deliverables: <br />59.4 A technical memorandum that includes: <br />- a description of each lysimeter study, the data collection period, a map showing the <br />geographic area of relevance, and its appropriateness for use in developing crop <br />coefficients <br />- a summary of previously developed crop coefficients from Subtask 59.2, their <br />appropriateness for use in SPDSS, and a map showing their geographic area of <br />relevance <br />- a summary of the Kimberly-Penman methodology and results compared to lysimeter <br />data and Blaney-Criddle estimates <br />- the recommendation for the development of local Blaney-Criddle crop coefficients <br />and/or the use of high altitude adjustments for use in SPDSS by geographic region <br />- locally calibrated Blaney-Criddle crop coefficients for the SPDSS study area <br />- potential consumptive use estimates at each key climate station for prominent crops <br />grown in the climate station geographic area. <br />This technical memorandum is expected to be an appendix in the final Historic Crop <br />Consumptive Use Report. <br />A data file of locally calibrated Blaney-Criddle crop coefficients in a format for use by <br />StateCU. <br />Task 62 -Review SPMAP, Develop a Plan for SPMAP and StateCU to Coexist Under <br />SPDSS, and Compare Results <br />SPDSS Consumptive Use and Water Budget Component 14 <br />
