the water-year l?UO-Ul (U.S.G.S., 19U2), taken at a station 2f miles 

 above the mouth, show discharges ranging from a maximura of 527 c«.f,So 

 in March to a minimum of OoU c,f,s» in July. On the date of observa- 

 tion the discharge at this point was 5.5 c.f.So and the water tempera- 

 ture was 80 F« The gradient is moderate. 2R-'(1) North Hornet Creek 

 enters the main stream about 8 miles above the mouth and extends for 

 12 miles. 2R-(l)a The Left Fork enters North Hornet Creek U| miles 

 above the mouth of the latter and extends for 7 miles to its so\arce 

 in constant springs. There were 13 irrigation diversions on Hornet 

 Creek. Three of these were of fair size, each withdrawing 3-1; c.f.s. 

 The stream was reported to have formerly supported good runs of 

 Chinook salmon and steelhead trouto The headwaters are still of some 

 value to steelheads, although the irrigation diversions present 

 hazards to downstream mlgrants# Because of the extensive withdrawal 

 of water for irrigation. Hornet Creek is of no present or potential 

 value to salmon. 



2S. Mill Creet o->^ (Not surveyedo) Mill Creek enters the Weiser 

 River approximately 58 miles above the mouth. The stream is about 

 7 miles long. There were nine irrigation diversions. There were no 

 reports of salmon entering the stream in recent years. Because of 

 its small size and use for irrigation. Mill Creek is of no value to 

 salmon* 



2T» Fort Hall Creek . — (Not surveyed©) Fort Hall Creek enters 

 the Weiser River approximately 60 miles above the mouth. It is a 

 very small stream, about 3 miles long. There were three irrigation 

 diversions. There were no reixjrts of salmon entering the stream. 

 Because of its small size and use for irrigation, Fort Hall Creek is 

 of no value to salmon. 



2U. West Fork, Weiser River . — (August 29, 19Ulj Frey and Bryant.) 

 The West Fork enters the Weiser River approximately 61 miles above the 

 mouth. "Hie stream is about lii miles long. Gaging-station records for 

 the water-year 19UD-m (U.S.S.S,,19U2), taken at a station 1^ miles above 

 the mouth, show discharges ranging from a maximum of 350 c.f.s. in April 

 to a minimum of 2 c.f.s. in Jiily. On the date of observation the dis- 

 charge at this point was h6 c.f.s. There were three irrigation diver- 

 sions on the stream, the largest withdrawing about 6 c.f.s. The West 

 Fork was reported to have formerly supported good runs of chinook sal- 

 mon and steelhead trout, and it is still of some value for steelhead. 

 The Chinook rwa has been greatly depleted, and the stream is of little 

 present or potential value for salmon because of the extensive with- 

 drawal of water for irrigation. 



2U-(1). Lo st Creek . — (August 29, 19Ulj Frey and Bryant.) Lost 

 Creek enters the West Fork of the Weiser River approximately 8 miles 

 above the mouth. The stream is about 21 miles long. Gaging-station re- 

 cords for the water-year I9U0-U. (U.S.G.S., 19U2), taken at a point ^ 

 ndle below the Lost Valley reservoir dam, or about 10 miles above the 

 mouth, show discharges ranging from a maximum of 18U c.f.s. in May to 

 a minimum of 2 c.f.s, in October. On the date of observation the dis- 

 charge at this point was about U9 c.f.s* There was very little dis- 

 charge from October through March, when water was being impoxmded,
