Clatskanie Falls at the upper terminus of the survey is 8 feet 

 high and fcrnerly was impassable to fish except at high water o Re- 

 cently a passage i^ras blasted through one side of the falls by the 

 Oregon Fish Commissiono The Oregon Commission is also iniproving 

 the lower section of the stream for the passage of fisho 



There is spavming area for several hundred salmon below the first 

 log jam, and for about 2,000 more fish up to the falls « Although no 

 salmon were observed, local residents rejxirt snail runs of fall Chinook, 

 dilver, and chum salmon and steelhead trout. 



Three small tributaries. Fall , Conyers , and Carcus Creeks , had 

 flows of 2 'j.foSo, but are of little value to salmon o 



15A. Beaver Creek .— (ifey 13, 19U^', Parkhurst, Brewington,, Gangmark, 

 and Fulton). Beaver Creek enters the lower slough-like portion of the 

 Clatskanie River at a point 1^ miles above the Columbia^ opposite the 

 upper end of 7fe.llace Island. The stream is 16 miles long, of which the 

 lower 2^ miles are tidal slough, and was surveyed for a distance of 3o7 

 miles above tidevrater. 



The stream was 15-30 feet wide, and was discharging 10 CofoS. The 

 water temperature was 52-59° F. There is spawning area for several hun- 

 dred salmon in the first 3 miles above tidevrater to an impassable falls 

 UO feet in height. The stream was surveyed for a distance of 3/4 mile 

 above the falls, in which there is a steeper gradient and the stream 

 bed consists mainly of bedrock and boulders. At a point 5 miles above 

 tidewater two falls, 10 feet and 6 feet in height, and tvro bad log jam;3 

 were found. Numerous silver and chum salmon fingerlings were seen be- 

 low the lower 40 foot falls. A >vinter run of steelhead trout and a fall 

 run of sea-run cutthroat trout were reported, 



15A-(1). South Fork , Beaver Creek . — (June 10, 1942 j Parkhurst). 

 Enters Beaver Creek above Beaver Creek Falls, and is not accessible to 

 migratory fisho It is a small stream, of little value to fisho 



16. Goble Creek . — 



17. Tide Creek . — (May 14, 1946; ParWiurst, dimmer, and Brewiiigton) o 

 Both streams enter the Columbia just below Deer Island. 'They are 7-10 

 miles long and carry little vra.ter during the summer » linpassable falls 

 10-12 feet in height are located about l/'S miles above the mouth of each. 

 The water temperature vras 50-52° F. , and both streams were discharging 

 20-25 Cof.So 



Both streams have SjDawning area for a few fish belov^ the falls and 

 small additional amounts above. A few steelhead trout and chum salmon 

 are reported to ascend to the falls on Goble Creek during the higher 

 water stages in late fall, but tide gates prevent the entrance of ajiy 

 migratory fish into Tide Creek o
