(iii) When the total natural flow of the Middle Fork Poplar River, as 



determined below the confluence of Goose Creek, during the immediately 

 preceding March 1st to May 31st period is greater than 9,250 cubic 

 decameters (7,500 acre-feet), but does not exceed 14,800 cubic decameters 

 (12,000 acre-feet), then a continuous minimum flow of 0.085 cubic metres 

 per second (3.0 cubic feet per second) shall be delivered to the United 

 States on the East Poplar River at the International Boundary during the 

 succeeding period June 1st through August 31st. A minimum delivery of 

 0.057 cubic metres per second (2.0 cubic feet per second) shall then be 

 maintained from September 1st through to May 31st of the following year.

(iv) When the total natural flow of the Middle Fork Poplar, as determined 



below the confluence of Goose Creek, during the immediately preceding 

 March 1st to May 31st period exceeds 14,800 cubic decameters (12,000 

 acre-feet) then a continuous minimum flow of 0.085 cubic metres per 

 second (3.0 cubic feet per second) shall be delivered to the United States 

 on the East Poplar River at the International Boundary during the 

 succeeding period June 1st through August 31st. A minimum delivery of 

 0.057 cubic metres per second (2.0 cubic feet per second) shall then be 

 maintained from September 1st through to May 31st of the following year. 

 In addition, a volume of 1,230 cubic decameters (1,000 acre-feet) shall be 

 delivered to the United States upon demand at any time during the 12- 

 month period commencing June 1st. 



(c) The natural flow at the International Boundary in each of the remaining 



individual tributaries shall not be depleted by more than 60 percent of its 

 natural flow.
