acre-feet (see Appendix D). Assuming a worst case scenario that all freshwater available is delivered with no losses and that a tailwater collection system exists, the additional 2,643 acrefeet of blended water would require an additional application area of 816 acres, using the planning value of 3.25 acre-feet per acre per year application factor. The additional 816 acre requirement means the existing actual application acreage is deficient by 816 acres and the needed 2028 application acreage is deficient by 1,157 acres when blending water is considered.
