A diversion dam 5 feet in height is located 1/3 mile above the 

 mouth. It has a fair fishway^ and the diversion of 1-2 Cof.So is 

 screened. 



The Westport water supply diversion dam is 4 feet in height and 

 is located 1 mile above the mouth. The diversion of 1.5 cf.s. is 

 screened. The dam is difficult for fish to pass during low viater 

 periods . 



There are tvro impassable waterfalls 8 feet and 6 feet high lo- 

 cated l^- miles above the mouth. A series of 3 additional waterfalls 

 8, 30j and 15 feet high are located 300 yards farther upstream, and 

 other barriers J including an abandoned 30 foot high dam^ exist above. 



Spawning area for a few salmon occurs in the. lower ij miles. 

 The obstructions and steep gradient above this point render the re~ 

 mai.-'ler of the stream inaccessible to migratory fish. A few salmon, 

 presumably silvers and chums, enter in the fall, but are reported to 

 be greatly molested by some persons in Tfestport. The only improve- 

 ment warranted on this stream, would be the elimination of pollution 

 in the lower section. 



11, Vfcst Cree k. -'"(or Dave Vifest Creek) 



12, Oleson Creek .— 



13, 0. K. Creek .— 



14, Tandy Creek . — (inspected June 11, 1942 j Parkhurst). These 

 are all small streams discharging less than 5 c.f.s. and entering the 

 Columbia within 5 miles above Westport, Oregon. Because of their 

 small size and general absence of suitable spawning areas none are of 

 value to salmon. 



15, Clatskanie River .— (October 11^, 1945 5 Parkhurst., Brewington^ 

 Davis, and Johanson). Enters the Columbia at Clatskanie, Oregon,, and 

 is about 25 miles long, of which 12 miles were surveyed from tidevrater 

 to an impassable vfaterfall 7 feet in height. The stream was 15-18 

 feet wide (at low water stage) and discharging 5 c.f.s. The Tj-ater 

 temperature Viras 50-55° F. 



The lower 1^ miles are slough-like j the succeeding 8 miles up- 

 stream contain suitable spatming areas, followed by a 3 mile section 

 up to Clatskanie Falls iiaving a steeper gradient and little suitable 

 spawning area. 



There vrere 9 beaver dams and 3 log jams that were diff iciolt or 

 impassable to fish at low water stages .
