waste disposal system. However, if growth should occur in 

 some areas of the basin, additional surface and ground water 

 demands could be placed on the Clark Fork system. Potential 

 future irrigation and mining water needs are discussed 

 separately following the sections on instream flow needs. 



Instream Flow Reservation Needs in the Basin 



In addition to the flows already requested by DFWP in 

 the upper river (above Milltown Dam) , the DFWP has developed 

 the following tentative list of streams and stream reaches 

 within the Clark Fork Basin that need instream flow reserva- 

 tions for protection of fisheries resources:
