The Corps selected appropri ate des i gns to provide dependabl e yi e 1 ds from ter- minal storage sites sufficient to restore and maintain lands in New Mexico, Oklahoma and Texas from the two southern routes (C and D); while the two northern routes (A and B) were designed to meet Kansas, Colorado, Nebraska, and Oklahoma needs, plus one-third of Texas' needs. In consultation with the General Contractor, the Corps agreed to increase the needed quantities to reflect the assumption that a 10 percent loss factor woul d be used to account for probabl e losses between the ter- minal reservoirs and actual on-farm delivery. The following table shows the year 2020 water demand, by state, and the required terminal storage to pro- vide that level of dependable yield. SOURCE STORAGE The use of the 1 argest avail ab 1 e source storage all ows the maxi mum yield from the source river. It is also important from a cost standpoint to have the source storage located as close to the source ri ver as possi b 1 e. This is necessary because the pumps and pipelines which remove and carry the water when available from the source stream to the source reservoir are much larger than the capacity of the canal system which is designed to remove the water from the source reservoir at a constant rate. 18
