The consumptive use work group (CUWG) has need for accurate and timelier consumptive use information than is now possible through the current basin-wide efforts such as the consumptive use and loss reports published by the bureau of reclamation. The compact empowers the commission to make findings of the quantity of colorado river system water used each year in the upper colorado river basin and in each state thereof. In the event that curtailment of use of water by the states of the upper division shall become necessary to comply with article III of the colorado river compact of 1922, the 1948 compact requires the commission to determine the timing and quantity of curtailment required by each upper division state. In so doing, the commission requires accurate and timely annual consumptive use information for every water year. Consumptive use information for the water year (1 october 30 september) is needed provisionally by 1 january and final estimates by 1 april (6 months after the end of the water year).
