TITLE OF STUDY ; Evaluation of Management of Water Releases 

 for Fisheries from Painted Rocks Reservoir, Bitterroot River, 

 Montana (BPA Project 83-463)

OBJECTIVE ; Evaluate the effects of dewatering on trout 

 populations. Develop a water management plan to optimize the 

 use of limited water through timed discharges from Painted 

 Rocks Reservoir. 



DURATION ; 1983 - 1986 



CURRENT STATUS ; Spring and autumn fish population estimates 

 have been conducted on three sections of the river. The 

 physical characteristics of several study sections have been 

 measured. Water temperatures have been continuously recorded 

 at four stations. Stream discharges have been measured on 

 the river and at major irrigation diversions. Test releases 

 of water from Painted Rocks Reservoir have been completed. 



Reports available from DFWP in Missoula include;
