Vegas artesian basin, an attempt was made to estimate the average annual recharge to the basin, and the figure of between 30,000 and 35*000 acre feet per year was arrived at. The discharge has been inventoried for several years, and 1 don't have that figure handy, but It Is as last year, something like 3^,000 acre feet—a little bit more perhaps, Q» Is that a measured discharge or the total discharge? A, That's the measured discharge, Q, Is there any discharge other than the measured discharge? A. Yes, there is discharge of the ground water through the use of plants and through evaporation from the soil. There are a variety of plants and grasses growing that depend on ground water for their water supply. These plants send their roots and draw from the ground water and primarily altogether from the shallow form of aquifers. That, together with the evaporation from the shallow zone, was estimated at the time the report was prepared, to range between five and 8,000 acre feet a year, Q, Does that include leakage? A. That water which is in the shallow zone probably is composed of water leaking upward through faulty wells — through faults that have occurred in the alluvian, and in part from the irrigation. It's difficult to say — it's impossible to say what part is contributed from each.
