 boundary flows be divided equally between the United States and Canada in

In August 1977, the Governments of the United States and Canada, pursuant 

 to Article IX of the Boundary Waters Treaty of 1909, referred the matter 

 of water quality in the Poplar River Basin to the IJC. The reference 

 specifically requested the IJC to examine and report on the water quality 

 of the Poplar River, including the transboundary water quality implica- 

 tions of the thermal power station of Sask Power and its ancillary 

 facilities. A study was completed by a multi-disciplinary team of 

 scientists from Canada and the United States and a summary of findings 

 and recommendations was published in January 1981. 



The Poplar River Bilateral Monitoring Committee was authorized for an 

 initial period of 5 years by the Governments of Canada and the United 

 States under the Poplar River Cooperative Monitoring Arrangement dated 

 September 23, 1980. A copy of the Arrangement is attached to this report 

 as Annex 1. On March 12, 1987 the Arrangement was extended by the 

 Governments for 4 years to March 1991. 



The Committee is composed of representatives of the Government of the 

 United States of America, State of Montana, and Government of Canada and 

 Province of Saskatchewan. In addition to the representatives of Govern- 

 ments, two ex-officio members from the State of Montana and Province of 

 Saskatchewan who reside in the Poplar River basin participate in the 

 activities of the Committee. Table 1 lists the members and ex-officio
