The stream gradient is fairly steep. At points 13 and 132 "niles up- 

 stream there are 2 small 4- to 5-foot high power dams supplying local 

 resorts o The do-'jmstream aprons and the addition of flash boards to 

 these dams make them jjnpassable at low water. There is spawning area 

 for at least 3„000 fish below the dams_, and for several hundred ad-- 

 ditional fish in the main stream above. 



In the years before hatchery racks were installed at the mouth 

 of the stream and before the small power dams were built there were 



xcellent runs of spring Chinook salmon and even larger runs of 

 steelhead into the Breitenbush and its two forks. The last big run 

 of steelhead was reported in 1934" The entire Breitenbush stream 

 system wr!/' be rendered inaccessible to anadromous fish by the Detroit 

 Dam. 



25S-(2)j-io North Fork Breitenbush River .—(.July 18, 1938| 

 ParKharst and WildingTJ The stream is 10 miles long, of which 6^ miles 

 were surveyed. The discharge was 72 c.f.s.^ at the tine of observa- 

 tion. The -yrater temperature was 54° F. The stream gradient is fairly 

 steep. The lower 5-niile section has an interlacing channel system 

 wi^h spawning area for more than 2,000 salmon. The stream formerly 

 supported good runs of box,h salmon and steelhead. 



25S-(2)j~ii. South Fork. Breitenbush River .— (July 14-15,. 1938s 

 Parkhurst and li/iiding,) The stream is 8 miles long^ of vfh.ich the lower 

 1.7 miles v/ere surveyed up to an impassable 12-foot high falls. The 

 stream is fed by glaciers on Mt. Jefferson and was dischai'ging 106 c.f.s< 

 The gradient is steep throughout. There vras spawning area available 

 for at least 1.000 fish. Good runs of salmon and steelhead formerly 

 entered the stream. 



25S-(2)1. Pa melia Creek .--(inspected September 27. 1937^ Hanavan.) 

 The stream is about 7 miles long. It arises from glaciers on Mt. 

 Jefferson, and was discfarging 130 c.f .s. The water temperature was 

 45*^ F. The gradient is steep, the stream having many cascades and a 

 few log jams. Tiiere is spa.wning area for a few hundred salmon. A few 

 Chinook salmon and steeiliead utilize the sjjavming area i^articularly in 

 the lower mile.

 Enters the North Sant.iara approximately 75 miles above the mouth« The 

 stream is 7 miles long^ of vfhicn 3t miles were surveyed up to impassable 

 40'-foot high Gatch Falls. The disctiarge was 120 c.f.s., and the water 

 temperature was 48^ F. The stream gradient is steep for most of the 

 course.. The stream forms a network of interlacing channels near the 

 mouthy and contains spawning area for at least 1^,500 saLmono Former 

 runs of spring Chinook and steelhead have been intercepted in recent 

 years by the hatchery racks on the main Santiam.
