<p><span>The States of </span>Nebraska<span> and Kansas are negotiating a compact for apportionment of the waters of the </span>Big<span> and </span>Little<span> </span>Blue<span> Rivers. So that the negotiating officials could allocate the water equitably, the amount of </span>streamflow<span> </span>depletion<span> caused by ground‐water withdrawals upgradient from the State line needed to be determined. At the request of the </span>Nebraska<span> officials, the U. S. Geological Survey constructed an electric </span>analog<span> </span>model<span> which could be used to determine the amount of </span>streamflow<span> </span>depletion<span> expected to occur in the next 60 years. The </span>model<span> simulates hydraulic conditions in an area of 7,400 square miles which includes the entire area drained by the </span>Big<span> and </span>Little<span> </span>Blue<span> Rivers in </span>Nebraska<span>. The trans‐missibility of the aquifer (Pleistocene in age) ranges from less than 1,000 to as much as 300,000 gallons per day per foot, and the storage coefficient averages about 0.20. The transmissibility values are based on examination of test‐ hole samples from more than 400 test holes in and adjacent to the </span>basin<span>. Analysis of the </span>model<span> indicates that predicted maximum ground‐water withdrawals between 1962 and 2022 will not deplete the base flow of the </span>Big<span> or </span>Little<span> </span>Blue<span> Rivers by more than 5 percent.</span></p>
