Groundwater constitutes one of the major sources of water for municipalities, irrigators, and rural dwellers. Conflicts between groundwater users are bound to arise from time to time, as is evidenced by a recent Missouri case, Higday v. Nickolaus, discussed elsewhere in this issue.' Such conflicts may increase in frequency in the future as the demand for groundwater increases. Although a majority of cases will involve allocation of groundwater between users of that class of water, many groundwater diversion cases will involve adverse effects on the flow of water in streams. It is –to the latter situation that this article is directed.
