Description 



The irrigation dam has a poorly 

 designed fishway and an un- 

 screened diversion channel just 

 above the dam. This was for- 

 merly good salmon spawning 

 area. 



The old sluice dam, not in use at 

 present, has an inadequate fish- 

 way. The dam is in poor repair 

 and structure is rotten. 



Fishway in dam closed during 

 salmon run. Salmon drop back 

 into irrigation ditches and die 

 unspawned. Many fry are lost 

 in ditches. 



Dam Is 12 to 15 feet high. Fish- 

 way is very poor and usually 

 dry during salmon run. This 

 was formerly a good sockeye 

 spawning area. Flume to tur- 

 bines is unscreened. 



Dam is 32 in. high with no fish- 

 way installed and during low 

 water is a complete barrier to 

 salmon migration. Unscreened 

 diversion above dam. 



The 3-foot dam has no fishway 

 and cuts ofl the former main 

 spawning area. Also has un- 

 screened diversion. 



Fishway now installed is not sat- 

 isfactory for passage of salmon. 

 Formerly important spawning 

 area; now nearly depleted. 



Divert Klokkon Creek into orig- 

 inal channel emptying into 

 Conni Lake. Sockeye formerly 

 spawned in this area. 



Remedial measures 



Install satisfactory fisli- 

 way and revolving screen 

 on diversion channel. 



Remove dam or install 

 efficient fishways. 



Install revolving screens 

 on diversions and have 

 sufficient water guaran- 

 teed during salmon runs 

 for proper operation of 

 fishways. 



Construct new fishpass 

 over dam and screen 

 turbine intake. 



Construct fishway in dam 

 and install revolving 

 screen in diversion. 



Install fishway and con- 

 struct revolving screen 

 in diversion. 



Construct proper fishway. 



Divert creek into old 

 channel.
