The present investigation examined the current water demand characteristics and the future water demand of Cache Valley, Utah for the time period of 1990-2010. The demand attributable to agriculture and seven nonagricultural economics sectors was determined and forecasts were performed based on those demand values.

Linear regression, extrapolation, and alternative futures forecasting methods were applied and the various results compared against each other. Three different scenarios were calculated for residential demand to represent different sources and composition of demand information. It was determined that consideration of water demand data excluding Logan City provided the best statistical description of water demand.

A discussion of the probable changes in the three water demand components, agriculture, industrial and residential, addressed issue of conservation and change of use patterns which would impact on the need for future development of new water supplies to meet the forecast demand for Cache Valley, Utah.
