3.2.4 On-Demand Release 



In addition to the minimum flow, the IJC apportionment recommendation entitles Montana to an on- 

 demand release to be delivered during the twelve month period commencing June 1 . Based on the 

 runoff volume of 2 740 dam^ recorded at the Poplar River at International Boundary gaging station 

 during the March 1 to May 31, 1993 period, Montana was entitled to a release of 370 dam^ from 

 Cookson Reservoir during the twelve-month period commencing June 1, 1993. Montana requested 

 this release to be made between May 12 and May 30, 1994. A volume of 391 dam^ was delivered 

 during this period.
