The principal tributaries are McGoviran , Parsons , Mill , Gash , and 

 Sho tK'on Creeks , each of vfhich liad observed discharges of 5-10 c.f .s. 

 All other tributaries vrere carrying less than 3 c.f.s., at the time 

 of the survey. 



25DD-(2). . Camp Creek . — (June 19, 193?' j Hanavan, Iforton, and 

 langtcn.) Enters the McKenzie River approximately 17 miles above the 

 mouth. The stream is about 9 miles long, of which 7.8 miles were sur- 

 veyed. The lovrer portion of the stream is 20-25 feet wide, and flov;s 

 sluggishly between dirt and brush covered banks 6-12 feet high in a 

 mile wide valley. This loyrer section of the stream is muddy and silt 

 covered, and lacks spawning area. The upper portion of the watershed 

 is in fairly high, brushy, logged-off hills. The entire river is full 

 of fallen logs and brush piles, often forming 2-4 foot falls in the 

 middle portion of the stream course. The upper 1^ miles siurveyed in- 

 cludes a series of 2-foot falls and cascades, and a 5-foot falls drop- 

 ping on a wide rock apron forms a barrier at the upper terminus of the 

 survey. 



A 7-foot lumber mill dam 3 miles above the raouth is impassable 

 when the mill is operating, as is a 6-foot mill dam a mile above. A 

 temporary mill dam 7 miles above the mouth would also be impassable 

 when in use. 



This stream appears to have no value to salmon, and no runs have 

 been reported. Except for cyprinids in the lower portion and a few 

 small cutthroat in the upper portion the stream is generally barren of 

 fish. 



25DD-(3) to (7). Johnson Creek , Ritchie Greek , Trout Creek , 

 Hatchery Creek , and Indian Creek are small 3 to 4 raile long tributaries 

 entering the McKenzie between Hendricks Bridge and Vida, Oregon. These 

 streams were believed to have little if any value to salmon, and were 

 not surveyed. 



25DD-(8). Gate Creek .— (June 6 and July 22, 1938; Parkhurst and 

 Wilding.) Enters the McKenzie Hiver approximately 38 miles above the 

 mouth. The stream is 2,2 miles long to the confluence of the North 

 and South Forks. It is 25-40 feet in vfidth, had an estimated dis- 

 charge of 35 c.f.s,, and the water temperature was 66° F,, on July 22. 

 The narrow valley is little cultivated, and is bordered by forested 

 hills. The banks- are steep and rocky, and marginal vegetation is dense, 

 The gradient is moderate, v/ith good pools and riffles. 



A run of spring chinook is intercepted at the Oregon State hatch- 

 ery racks on the main McKenzie. A series of hatchery rearing ponds 

 for spring chinook are formed by weirs in the creek 1/2 mile above the 

 raouth. Recently liberated fingerlings "^-U inches in length were numer- 

 ous below this point.
