There is good spawning area for at least 1,000 fish up to tne 

 forks . 



25DD-(S)a„bo The Horth and bouth Forks are each about 7 niles long 

 and had discharges of 1? c-f,s. The considerable anount of large 

 rubble in each limits the spavming area. The North Fork was suxveyed 

 for a distance of 2o6c miles, and contains potential spawning area 

 for approximately 250 salmon r On the South Fork at a point Oo7 mile 

 above the mouth there is a bedrock chute with a shallow 4-foot dr-op 

 that is normally a barrier » Below this falls there is spawning area 

 xor less than 100 salmon o 



25DD-(9) to (lA). Lkrtin Creek , Bear Creek , Deer Creek , Ennis 

 Creek , Quartz Creek , and Elk Creek .- — entering the I^cKenzie between 

 Gate Creek and Blue River did not appear to be good salmon streams, 

 and were not surveyed* These are all ^-b miles long, v/ith the ex- 

 ception of ^iuartz Creek, vfhich is 12 miles long and has a high per- 

 cent of large rubble and boulders . 



25DD-(15) Blue River .--(August 15-17, 1937j Baltao and Kolloen,) 

 Enters the HcKenzie River apiaroximately 55 miles above the moutho The 

 stream is about 16 r.iles long, of vj-hich the lower 11 miles were sur- 

 veyed. The dischiarge was 53 c.foS. The minimum recorded flow was 

 13 c.f .s., on September 27, 28 and October 1, 2, 1938. The maximum re- 

 corded flow was 8,020 Cof.s., on December 31, 1942 » T'^e flov/ from 

 July througii October is usually 20-75 cf.s. (U. SoG.S. records). The 

 gradient is fairly steep in the lower mile, moderate in tb.e next 5 

 miles ifdiere the valley widens, and becomes increasingly steep in the 

 upper section. Except for the one slightly wider section, the valley 

 is narrow and the \mlls are steep and heavily wooded. The v/ater tem- 

 perature T/as 58-62° F. 



A 9-foot falls located 2-| miles above the mcuth is impa.s sable ex- 

 cept at flood stages. Numerous low falls above the lower 6 miles axe 

 passable only vfith diff Icalty. 



A large part of the strean bed is composed of large rublr)le, 

 boulders, and occasional patclies of bedrock. The gravel of suitable 

 size for spavming is so evenly distributed throughout the larger 

 material that much of it cannot be utilized to its fullest extent. Good 

 riffles are scarce, and the only good spavming areas are located at the 

 lovrer ends of the numerous large resting ix)ols . !lany of these large, 

 deep pools are excellent for holding spring chinook salmon ttirough tte 

 suriimer. There is potential spavming area available for at least 2,000 

 salmon. Old residents re|X)rted tliat large salmon formerly entered the 

 stream. In more recent years only a portion of t!ie salmon allowed to 

 pass the racks on the main ilcKenzie ascend to the Blue River. RainboYir 

 trout of good size were numerous in the upper section of tb.e river o
