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 

 then 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 617 cubic decameters (500 acre-feet) shall be delivered to 

 the United States upon demand at any time during the 12-month period 

 commencing June 1st. 



(iv) 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 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 to 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 tribu- 

 taries shall not be depleted by more than 60 percent of its natural flow. 



3. The natural flow and division periods for apportionment purposes shall be determined, unless 

 othenwise specified, for periods of time commensurate with the uses and requirements of both 

 countries.
