Show COLUMBIA RIVER TREATY 421 tions. Unless otherwise agreed by the entities the average weekly out- flows shall not be less than 3,000 cubic feet per second at the dam de- scribed in Article 11(2) (a), not less than 5,000 cubic feet per second at the dam described in Article 11(2) (b) and not less than 1,000 cubic feet per second at the dam described in Article 11(2) (c). These minimum average weekly releases may be scheduled by the Canadian entity as required for power or other purposes. Flood Control 5. For flood control operation, the United States entity will submit flood control operating plans which may consist of or include flood control storage reservation diagrams and associated criteria for each of the dams. The Canadian entity will operate in accordance with these diagrams or any variation which the entities agree will not derogate from the desired aim of the flood control plan. The use of these diagrams will be based on data obtained in accordance with paragraph 2. The diagrams will consist of relationships specifying the flood control storage reservations required at indicated times of the year for volumes of forecast runoff. After consultation with the Canadian entity the United States entity may from time to time as conditions warrant adjust these storage reservation diagrams with- in the general limitations of flood control operation. Evacuation of the storages listed hereunder will be guided by the flood control storage reservation diagrams and refill will be as requested by the United States entity after consultation with the Canadian entity. The general limitations of flood control operation are as follows: (a) The Dam described in Article 1I{%) (a).-The reservoir will be evacuated to provide up to 80,000 acre-feet of storage, if re- quired, for flood control use by May 1 of each year. (b) The Dam described in Article II(2) (.6).-The reservoir will be evacuated to provide up to 7,100,000 acre-feet of storage, if required, for flood control use by May 1 of each year. (c) The Dam described in Article II(2)(c).-The reservoir will be evacuated to provide up to 700,000 acre-feet of storage, if required, for flood control use by April 1 of each year and up to 1,270,000 acre-feet of storage, if required, for flood control use by May 1 of each year. (d) The Canadian entity may exchange flood control storage provided in the reservoir referred to in subparagraph (b) for additional storage provided in the reservoir referred to in sub- paragraph (a) if the entities agree that the exchange would provide the same effectiveness for control of floods on the Colum- bia River at The Dalles, Oregon. Power 6. For power generating purposes the 15,500,000 acre feet of Cana- dian storage will be operated in accordance with operating plans de- signed to achieve optimum power generation downstream in the United States of America until such time as power generating facilities are installed at the site referred to in paragraph 5 (a) or at sites in Canada downstream therefrom. |
