Ladies and Gentlemen: 



During 1992, the Poplar River Bilateral Monitoring Committee continued to fulfill the responsibilities 

 assigned by the governments under the Poplar River Cooperative Monitoring Agreement dated 

 September 23, 1980. Through the exchange of Diplomatic Notes, on March 12, 1987, the 

 Arrangement was extended to March 1991. In July 1992, another exchange of Diplomatic Notes 

 extended the Arrangement retroactively from March 31, 1991 to March 31, 1996. In addition, the 

 Arrangement was modified to terminate quarterly exchange of data and substitute an annual 

 exchange of data. 



The enclosed report summarizes current conditions and compares them to guidelines for specific 

 parameter values that were developed by the International Joint Commission under the 1977 

 Reference from Canada and the United States. After examination and evaluation of the monitoring 

 information for 1992, the Committee finds that the measured conditions meet the recommended 

 objectives. However, the Committee notes that flow-weighted concentration of total dissolved solids 

 in streamflow in the East Poplar River at the International Boundary continues to increase and is 

 approaching the long-term objective of 1 ,000 milligrams per liter 



During 1992, monitoring continued in accordance with Technical Monitoring Schedules outlined in 

 the 1991 Annual Report of the Poplar River Bilateral Monitoring Committee. 



Herein is the 12th Annual Report of the Poplar River Bilateral Monitoring Committee. This report 

 discusses the Committee activities of 1992 and presents the proposed monitoring schedule for 1993. 



Yours sincerely.
