Estimate of underflow in the Niobrara River Basin across the Wyoming-Nebraska state line

Open-File Report 57-4
By:  and 



The purpose of this report is to estimate the amount of ground water flowing across the Wyoming-Nebraska State line within the Niobrara Rive basin and to evaluate the accuracy of that estimate. The approximate effort involed in obtaining additional data to determine the underflow more accurately also is discussed.

This report was prepared by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and Director of the Conservation and Survey Division of the University of Nebraska, at the request of the Niobrara River Compact Commission. The following paragraph requesting the work is quoted from the report of the Engineering Subcommittee to the Niobrara River Compact Commission, Ainsworth, Nebr., October 29, 1956:

Need for additional data under this item is confined to ground-water data since surface-water data discussions are covered under item 1. It is recommended that the Commission request the Geological Survey in cooperation with each of the three states to develop estimates of ground-water flows across state lines, together with ground-water contour maps extending adequate distanced into each state, such estimates and maps to be based on existing data and qualified by their evaluation of resultant percentage degree of accuracy. In addition they should be requested to furnish an estimate of cost to obtain additional data necessary to bring the estimate to within a more acceptable degree of accuracy as may be desired by the Commission.
