<br />. <br /> <br />""- <br /> <br />more frequently as conditions warrant. If conditions change <br />sufficiently, the recovery potential, as described above, <br />would be evaluated and modifications would be made to the <br />plan as warranted. <br /> <br />By far the most var iable factor in the development of an <br />AOP is the projected water supply. Although the accuracy of <br />the water supply forecast is dependent upon highly <br />unpredictable future climate conditions, the ability to <br />depict present conditions and to update water supply <br />forecasts has significantly improved. This improvement can <br />be attributed to the 1984 installation of the Colorado River <br />Basin real-time hydrometeorologic data network. This network <br />consists of snotel, precipitation, temperature, and stream <br />gaging stations throughout the Basin. This network reports <br />data every six hours which are input to conceptual based <br />forecast models. Whereas past forecasting techniques using <br />regression models provided for only monthly updates of <br />projected water supply, the conceptual models can provide for <br />virtually instantaneous updates. <br /> <br />3.6 Role of Federal/State Colorado River Management Work <br />Group (Work Group) <br /> <br />The federal/state Work Group was formed to develop a <br />recommended process wherein AOP's for the Colorado River <br />system would be formulated during periods of full reservoir <br />and excess water conditions. The Work Group would continue <br />to function as a federal/state working committee to jointly <br />develop and evaluate future AOP'S, and to advise the <br />Secretary of the Interior and the Basin states' governor- <br />appointed representatives for review of river operations as <br />to projected river and water supply conditions, consumptive <br />water use needs, and as to a recommended AOP for the coming <br />water year and proposed revisions thereto. The <br />responsibilities of the Work Group would continue throughout <br />the year with the monitoring and assessment of the AOP. This <br />continuous participation could ensue as follows: <br /> <br />1) Each year in June, the Work Group would initiate the <br />process of quantifying excess water availability for the <br />following year based on the considerations described in <br />Section 3.2. This quantification would form the basis for <br />developing an initial operating plan and guide the evaluation <br />and development of the recommended AOP. The analysis of <br />potential water supply availability for the following year <br />would also be used to confirm or to make recommendations to <br />modify the current operating plan for the period July through <br />September. <br /> <br />-40- <br />
