SUliMARY OF RECOLDMENDATIONS 



Imnaha River 



Since the Imnaha has not heen subjected to demands for water use, 

 it is a stresun in which r\ins of chinook salmon and steelhead trout may- 

 be maintained, and every possible attempt should be made to restore 

 the runs to their former abundance. 



Pine Creek 



The decreased volume of flow during the stunmer months over the 

 wide stream bed in the Pine Valley region, due to numerous small 

 irrigation diversions, has had the twofold effect of causing high 

 water temperat\u*es and hampering the upstream migration of salmon. 

 Since the agricultural demand for water does not pennit the allev- 

 iation of this condition, it is not advisable to atten^t the res- 

 toration of the salmon run into this stream. 



Powder River 



The barrier imposed by the Thief Valley Dam has rendered the 

 greater portion of the Powder River and most of the spawning area 

 inaccessible to migratory fish. The difficulty of constructing 

 adequate fishways over this storage reservoir dam of fluctuating 

 ?ra.ter level, as well as the necessity for screening numerous irri- 

 gation ditches above the dam and maintaining an adequate flow at the 

 time of salmon migration, make any program for the restoration of the 

 salmon run to the upper Powder River doubtful of success and eoonomi- 

 oally unfeasible. 



Eagle Creek, a large tributary to the lower Powder River, offers 

 excellent salmon spawning -area. Sufficient discharge should be allow- 

 ed from the Thief Valley Reservoir at the time of salmon migration to 

 insure the passage of salmon up to the mouth of Eagle Creek, 



Burnt River 



The difficulty of providing adequate fishways over the Unity 

 Reservoir Dam due to the great fluctuation in water level, and the 

 numerous irrigation diversions on Burnt River, together render the 

 stream of liti;le potential value to salmon. Therefore it is not 

 recommended that euiy attempt be made to restore the run of salmon 

 to this streEuiu
