into the Missoula Valley Aquifer by: 1) conducting surface 

 water discharge rates on the Clark Fork and Bitterroot River, 



2) measuring water level changes at six monitoring wells, and 



3) evaluating the discharge rates of two stormwater drain 

 systems and three septic tank disposal fields. Water quality 

 parameters are also being collected at all of these monitor- 

 ing sites. 



FUTURE ACTIVITIES ; The above monitoring program will 

 continue for two years. At that time, a numerical ground- 

 water model will be developed to predict the effects of 

 existing and proposed development and disposal practices on 

 the aquifer system.
