<br />. <br /> <br />. <br /> <br />1) DEMAND FORECASTING PLAN <br /> <br />Puroose: <br /> <br />Develop a plan for forecasting seasonal irrigation water demands, <br /> <br />Methods: <br /> <br />Boyle will review the estimates of crop water requirements <br />developed for the Norwood,Redvale service area in the Phase 1 <br />studies, Emphasis will be placed on accommodating reported <br />crop demands in late April in the lower portion of the service area. <br />Heavy reliance will be made on the work performed for the <br />Phase 1 studies, <br /> <br />Representative monthly crop water requirement distributions by <br />crop and by location in the service area will be developed, The <br />crops to be investigated are alfalfa, grass, spring grains, and corn, <br />The service area will be divided into an upper portion (Norwood) <br />and a lower portion (Redvale) with the division made at <br />approximately Coventry Hill, <br /> <br />Historic climatic data will be used to develop representative <br />average, wet, and dry year crop water requirement distributions <br />for each crop and for both portions of the service area, These <br />crop water requirement curves will be translated into reservoir <br />demand curves through consideration of transit losses and <br />application efficiencies, All of the curves described above are on <br />a unit demand basis in units of acre,feet per acre, <br /> <br />Farm specific reservoir demand estimates for average. wet, and <br />dry years will be developed using the information developed <br />above and data obtained during irrigator interviews regarding crop <br />type, irrigation application methods, and irrigated acreage, These <br />reservoir demand estimates will be entered into a database <br />developed for those parcels uniquely identified during the irrigator <br />interviews, The demands for each parcel when composited form <br />the total demand for the service area, The units associated with <br />the farm specific demands will be acre,feet. <br /> <br />A brief summary memorandum (5 pages) will be prepared <br />describing the procedures and data used in this analysis and <br />presenting the results. <br /> <br />Products: <br /> <br />o <br /> <br />Revised crop water requirement curves which incorporate <br />additional early season demands, <br /> <br />o Farm,specific reservoir demand estimates for <br />representative average, wet, and dry years incorporated <br />into a database corresponding to specific land parcels, <br /> <br />o Summary memorandum describing procedures and <br />results, <br /> <br />2 <br />
