It was estimated from counts made by the sur'vey party that there 

 were at least 1,20C spring chinook simwners in the main stream, of 

 which less than 50 were found belovf Staytono In addition, ttere were 

 nearly 1^000 spawners being held at the Detroit hatchery racks » These 

 fish ascend the river from April through July, and spawn mainly in 

 September, A good run of spring steelliead ascends the river from March 

 through May, spawning for the most part in the upper main stream and its 

 tributaries in llay and Juneo In the year 194-0 the hatchery take was 2^ 

 million steelhaad eggs, and it was estimated that there was a run of 

 iaore than 2^000 fish in the main river. 



25S-(2)co Little North Santiam o— (August 15-16, 194.0; Parkhurst 

 and Bryant"^ < Enters the North Santiam River at Meharaa., about 28 miles 

 above the routh , The stream is ai^proximately 30 miles long;, of which 

 the lower 15 miles up to the impassable 25-foot high Elkhorn Falls was 

 surveyed. The flow ranges from a minin).um of 21 Cof„So.j in September to 

 a maximum of 19,400 cf.So^ on November 23, 1942, The water temperature 

 ranged from 61°- 68° F«,, at the time of observation. The stream gradient 

 is moderate, being 30-40 feet per mile in the lower 20 miles o 



The stream flows through a wooded area in a steep canyonr Above the 

 lower 2 miles there are ma.ny large, deep, clear resting pools _., all of 

 which contained salmon , At a point about 12 miles upstream a narrow 

 resting pool 150 yards long and 10-30 feet deep, locally knoTm as"The 

 Narrows" contained approximately 200 spring chinooks. More than 70 

 chinooks vrere counted in the pool at the foot of Elkhorn Palls. Spring 

 Chinook salmon reach these pools during spring high water. Because of 

 the low summer flows fish are confined to some of these pools until the 

 first fall rains, when they move onto the spawning riffles. There is 

 spasming area available below the falls for at least 2,500 salmon, but 

 most of the spavming occurs above the lower 5 miles. The area above the 

 falls should be surveyed, as a fish ladder at the falls seemed desirable. 

 It was estimated that there were at least 500 spring chinook spawners in 

 the stream, and a good spring run of steelhead was reported. None of 

 the loT/er tributaries were of appreciable value to spawning salmono 



25S-(2)i. Blowoat Greek ,-- -Uuly 18, 193^5 i'arkhursto) Enters the 

 North Santiam approximately 56 miles above the mouth. The stream is 

 about 12 miles long, of which the lov/er 2 miles vrere siu"veyed to a series 

 of impassable cascades and low falls in a box canyon. The water tem- 

 perature tias 53° F. The stream gradient is fairly steep. There is 

 spawning area available for approximately 200 fish. A fevf steelhead 

 Tirere reported to enter the stream.. 



25S-(2)j, B reitenbush River .— (September 27-29, I9385 Ilanavan, 

 Lobell, Baltzo, and Kolloen.) Enters the North Santiam approxiniately 57 

 miles above the mouth. The stream is 13t miles long to the confluence 

 of the North and South Forks, and was all surveyed. The flow ranges 

 from a minimum of 87 c.f .3,, on September 2, 1940j to a maximum, of 9. ,710 

 c.foS., on November 23 j 1942. The water temperature ranged from 46°-5l°F,
