the bedrock around the east side of the falls, but at the time of obser- 

 vation it was in a state of disrepair and -was impassable* Big Falls, 

 30 feet high, is located about 32 miles above Steelhead Falls o It has 

 a fair 9-step fishway, but it too is impassable at times because of a 

 lack of -water, and at such times the falls must be considered as a 

 barrier* These falls marked the upstream limit of migration of chinook 

 salmon and steelhead trout under natural conditions, Odin Falls, 6 

 miles above Big Falls, is scarcely more than a cascade with a drop of 

 about 10 feet in $0 yards* Cline Falls, 5 miles above Odin Falls, has 

 a drop of about 30 feet plus an additional 3 feet created by a wooden 

 splash dam across the crest. The fishTjay was in a state of disrepair 

 at the time of observation. Aubrey Falls, 7 miles above Cline Falls, 

 is another cascade having a drop of about 15 feet in 100 yards. The 

 North Canal Dam, marking the upper boundary of this section of the 

 main Deschutes River, is a concrete structure 30 feet high* There is a 

 broken-dotm fishway at the center of the dam* Thus this dam, like the 

 falls, is a barrier to fish. At this point diversions have removed 

 so much of the flow that only a scant 15 or 20 c«f *s* is allowed to spill 

 over the dam during the period from March to November* During the 

 balance of the year additional water passes over the dam, but this could 

 benefit only a few late fall run steelhead trout in this section of 

 stream* This low flow makes it impossible to attempt to pass fish 

 through this section to the upper portion of the river* It is doubtfTil 

 that the upper stream sections are of great enough value to justify 

 fishways at the three falls and at the dam, even if a sufficient volume 

 of flow could be provided. Suitable spawning area is limited to a few 

 good riffles near Tumalo, Oregon* No tributaries of importance enter 

 this section* 



Section 3; The Swalley (80 c.f*s,) and North Canals (UOO c*f,Sa) 

 divert water at the North Canal Dam, A third large canal, built by the 

 U*S* Bttreau of Reclamation also diverts about 1,000 c*f»s« at this point 

 in connection with agricultiiral development in the Madras area* 



- The Deschutes County M\inicipal Improvement District dam, 7 feet 

 high, is located in the city of Bend* It 'is of concrete construction, 

 and has a 6-step fish-way. From 6O-8O c*f*s* is diverted at the dam to 

 supplement the Tumalo project feed canal. 



The Pacific Power and Light Company dam is located about 1/U mile 

 above the coiinty dam. It is about 15 feet high and has a poor fishway. 

 The Shevlin-Hexon Ixunber mill dam is located about 1 mile above the 

 Pacific Power and Light Company dam* It is of wooden construction, about 

 6 feet high, and has a good fish-way* The Scanlon-Brooks lumber mill dam, 

 located a short distance farther upstream, is similar to the Shevlin- 

 Hexon dam*
