25T-U. Second Periwinkle Creek and First Periwinkle Creek are 

 both small streams on the Willamette Valley floor and entering the 

 Willamette River between the Santiam and Calapooya Rivers. Neither 

 of them is of value to salmon, 



25V. Calapooya River . — (lower 26 miles inspected and the next 

 20 miles surveyed September 1-2, 19/4.5; Parkhurst, Hanavan, Silliman, 

 Rucker, and Brevj'ington . Next 13 miles to North Fork surveyed, Septem- 

 ber 29 - October 2, 1941; Prey and Bryant.) Enters the Vfillamette 

 River approximately 114 miles above the nouth. The stream is about 

 65 miles long. The flov/ at a point 34 miles upstream ranged from a 

 minimum of 13 c.f.s., on September 8, 1940, to a maximum of 9,400 c.f.s., 

 on December 31, 1942. The stream gradient is slight in the lower 26 

 miles, and moderate above. The y/ater temperature was 72° F., in the 

 lower 26 miles, 58-66° F., in the next 20 miles, and 47-51° F», in the 

 upper section. 



The Albany Ditch, leading from the South Santiam River, discharges 

 through the Mountain States Povrer Plant 1/2 mile above the mouth. The 

 power plant operates under a 36-foot head, and chinook salmon Jiave been 

 reported taken from the tailrace. 



A diversion dam 4 feet high located 21 miles upstream was divert- 

 ing 18 c.f.s., to a woolen mill at Brownsville, and the diversion is 

 unscreened. A fishv/ay over the dam is impassable at low water. 



The Finley Mill Dam at Crawf ordsville , 26 miles above the mouth, 

 is 10 feet high and is a barrier except at extreme high water stages. 

 At least 20 chinook spawners were observed to be held up below the 

 dam in September, 1945 • In 1941 a fevir salmon were reported to have 

 passed to the upper watershed vrinen part of the dam was temporarily 

 washed out. This dam, although not in use, has prevented the passage 

 of chinook salmon to the major spavming areas and is ilargely re- 

 sponsible for the depleted condition of the run in the Calapooya River. 



A series of cascades and rapids about 30 miles upstream and two 

 log jams 37 and 42 miles above the aouth were believed passable . A 

 log pond dam at Dollar, 48 miles upstream, v/ts a low water barrier in 

 1941, but was reported to have washed out in 1945* A log jam over a 

 lo\f falls 54 miles upstream was a total barrier. 



The lower 25 miles of the stream has a mud bottom and is of no 

 value to salmon. There is 1 mile of good spawning area below the 

 Finley Mill iJan, containing suitable sjavming area for approximately 

 1,000 salmon. There is spawning area for at least 9,000 additional 

 fish from the Finley iiam to the impassable log jam 27 miles above. 



The present run of salmon is very small, probably less than 100 

 fish, although in 1941 more than 200 spring chinook spavmers were re- 

 ported. Steelhead trout were reported as far upstream as the impassable
