3. If flow-weighting is to be maintained, it was recommended that 

 flow-weighted moving averages be calculated using geometric mean 

 flows, and that the regression relationship between parameters of 

 interest and conductance be derived from the daily conductance 

 readings, rather than from the monthly grab sample results. 



The report and recommendations are being studied by the Bilateral 

 Monitoring Committee and will be on the agenda at a future meeting. 

 However, the Committee determined that sampling at East Poplar 

 River at International Boundary would be decreased by 50 percent 

 (bimonthly sampling from both the USGS and EC would yield 12 

 samples annually rather than the previously collected 24).
