~13~ M32J2 The enormous water table below the valley floor llonstitutes rellerve storage, which to some extent equalizes the varying annual supplies and, of increasing importance in recent years, supplies the hundreds of irrigation wells in the main valley. It may be said that the valley supplies are from both the Kersey flow (itself mostly return water) and from returns in the valley and that they When the ditches and reservoirs are WIlli supplied from basic flows, the supplement each other. water tables rise in elevation, returns increase and the wells in the main portion of the valley operate with lower lifts. Possibly, future projects designed to help recharge these acquifiers, particularly in tributary valleys like Bijou and Kiowa, may be as worthwhile as surface sto..-age. liith the Conservancy District adding at least 30% to the "original" supplies on the upper tributary streams and with prospective increases to the river from the operations of the City of Denver, the Kersey discharges will continue to ga:l.n in coming years and, most important, become more uniform and stable. This will reduce the shortages in the valley and by the same token will also add to the surpluses that pass out of the State. These outflows will always continue and may increase. As the tabulations and charts show, there are large and fairly regular amounts of surplus water in the lower valley and smaller and more intermittent excess flows on the tributaries and at Kersey. Of course, the higher up any water can be conserved, the more value it will have in supplying the several cycles of diversions, application and return flow for re-use before leaving the State.
