dlTersloxis* Good runs of ohlnook salmon and steelhead fonnerly utilised 

 the spanning area, but these runs hare been greatly depleted in recent 

 years* Because of its extensive irrigation use the streeun is of no pre> 

 sent or potential Talue to salmon, and of only slight -value to steel- 

 head. 



2K» Griggly Creek, — (Not surreyed*) Griialy Creek enters the 

 YTeiser River approximately 42-^ miles above the mouth* The stream is 

 about 8 miles long. It had one small irrigaticn diversion of less than 

 1 o*f.8* The stream is not of sviffioient size to be of any value to 

 salmon or of more than slight value to steelhead* 



2Im Coir Creek* — (Not surveyed*) Coir Creek enters the Weiser 

 River approximately 43^ miles above the mouth* The stream is about 8 

 miles long* There were three irrigation diversions, only one of iriiioh 

 was of any importance* The stream is not of sufficient sixe to be of 

 any value to salmon or of more than slight value to steelhead* 



ZUa Bacon Creek .— (Not suiTsyed. ) Baoon Creek enters the Weiser 

 River approxiiaately 44^ miles above the mouth* It is about 7 miles 

 long* Excess water from the Mesa diversion of the Middle Fork of the 

 Weiser River flows into a pool at the head of Bacon Creek* If it were 

 not for this supplememtal flow. Bacon Creek would be dry during the 

 summer* There were no reports of salmon entering the stream* Because 

 of its small size and dependence upon an unnatural flow. Bacon Creek 

 is of no present or potential value to salmon* 



2N* Goodrich Creek .— (Not s'lrveyed*) Goodrich Creek enters the 

 Weiser River approximately 462- miles above the mouth. It is about 13 

 miles long* There were three sna.ll irrigation diversions, the largest 

 having a capacity of 0*4 o.f.s. The stream is one of those wtiioh 

 were reported formerly to have supported rvais of ohinook saLmon and 

 steelhead* It is of little present or potential value to salmon. 



2-0. Johnson Creek* — (Not surveyed© ) Johnson Creek enters the 

 Weiser River approximsTFely 48 miles above the mouth* It is about 13 

 miles long. There was one small irrigation diversion. Good runs of 

 Chinook salmon end steelhead trout formerly utilized the spavRiing area* 

 Although -Uiere are occasional reports of a few ohinook salmon in the 

 Btream, it is of slight present or potential value as a salmon producer* 

 It is of more value to steelhead because water oonditions are more fav- 

 orable at the time of the spring steelhead spawning migration* 



2P, l&ddle Fork, Weiser River .-« (August 19-22, 1941; Frey and 

 Bryant, ) The Middle Fork enters tiie Weiser River approximately 49^ 

 miles above the mouth. The stream is about 25 miles long, of whieh 

 15 miles were surveyed. It was 9 feet wide at the moizth euad discharg- 

 ing about 3 o.f.s* at the time of the suz'vey* Gaging-station records 

 for the water-year 1940-41 (U.S.G.S.), taken at a station 2^ miles 

 above the mouth, show discharges ranging from a maxiaum of 640 o.f.s* 

 In May to a minimum of no flow in part of August. The discharge at 

 this point on the date of observaldan was 7 o*f*8* The gradient is 

 moderate in the lower portion and increases upstream, becoming fairly 

 steep above Mesa Dam*
