The secondary or external benefits of increasing the availability of water for irrigation and changing the allocation of an existing water supply was analyzed from a theoretical point of view.

" Input-output" models for Cache County, Utah, and for the stat e of Utah were us ed to indicate the intersectoral relationship of water used by agriculture and other sectors in each economy.

The indirect value of water used by agriculture in Cache County was estimated. A method that extended the procedure used in this thesis was proposed that could be used to estimate the value of water in ether sectors. A "water matrix" was used to indicate reasons why large allocations of water to agriculture may be economically justified.
