temperature was 35 to 46 F„„ but summer temperatures are 

 reported to be higho It had 7 unscreened irrigation diversions 

 and 5 dams, as follov/s s 



An Indian Service concrete dam 9 l/S miles upstream has a drop 

 of 14 inches o This dam is usually passable to fisho 



fhe Indian Service Irrigation Canal takes off at the north 

 end of the dam and has a capacity of 110 CofoSo It is not 

 screened at present. 



The Shearer Irrigation Canal takes off on the south bank 11 

 miles upstream and above a brush dam that v:as not considered a 

 barrier at the time it was inspected^ The canal has a capacity of 

 10 c.foSo, is Tjnscreened, and is reported to be used only during 

 water periods. 



A small, unscreenedj irrigation ^ditch 4 feet wide takes off on 

 the north bank 12 1/2 miles upstream but v/as not in use when inspectedo 



An unscreened irrigation ditch 6 feet wide takes off on the north 

 bank 13 miles upstream above a 2 foot high log and rock dam. The 

 passability of the dam is questionable at low water stages. 



A similar unscreened ditch takes off on the north bank 26 l/2 miles 

 upstream, above a low rock diversion dam. 



The Satus Stock Ranch Irrigation Ditch takes off above a rook wing 

 dam on the south bank 27 miles upstream. It is 10 feet wide and im- 

 screened. 



An unscreened irrigation ditch 6 feet wide takes off from the south 

 bank 30 miles upstream. It is supplied by a rock diversion dam 2 l/2 

 feet high that is believed to be a low water barrier. 



A log and rock debris slide 4 to 5 feet high and 100 feet long 

 40 1/2 miles upstream is believed to be a low water barrier. 



The stream bed in the lower 6 miles of Satus Creek consists 

 mainly of mud and sand. The remainder of the stream possesses 

 considerable spawning area, which is often inaccessible and unusable 

 because of irrigation demands ^ Steelhead and salmon were reported 

 to have rtm into this creek prior to 1910, but there are few, if any, 

 at the present time. 



With the exception of Logy Creek, none of the tributaries of Satus 

 Creek have a sufficient flow in the fall months to provide for salmon 

 runs.
