 Row R, 



Portions of lower 

 Sandy and tribu- 

 taries. 



Important producer of spring 

 Chinook salmon. Present spawning 

 area threatened by proposed 

 water-use developments. 



Numerous good spawning areas 

 and resting pools. 



Finley Dam, built in 1847, about 

 72 km. above the mouth, blocked 

 runs for 102 years. Best spawn- 

 ing area became available after 

 this dam washed out in 1949. 

 Stream improvement work has 

 been accomplished, but runs are 

 still small. 



River has remained a good pro- 

 ducer in spite of losses of both 

 upstream and downstream migrants 

 at following projects: Irriga- 

 tion District Canal, Eugene- 

 Springfield Supply Diversion, 

 and Walterville Canal. A barrier 

 and bypass at Walterville Canal 

 and bypass at Leaburg Power 

 Plant are needed for adults. 

 Screens are needed at the diver- 

 sions. Stream has excellent 

 water supply, proper size of 

 gravel, and suitable gradient 

 for spawning. Produces largest 

 run in Willamette system (esti- 

 mated at 45-50 percent). 



Cougar Dam, dedicated May 9, 

 1964, is about 6 km. from mouth. 

 Strube Dam, to be constructed 

 3 km. down from Cougar, will 

 regulate flow. Important spawn- 

 ing area will be inundated, but 

 area above dame will be kept in 

 production by fish passage 

 devices. 



Spring runs which formerly 

 spawned above Dexter Dam are 

 now maintained by the Willamette 

 Hatchery (O.F.C). Many fish 

 lost in holding ponds because of 

 disease in former years. Im- 

 proved treatment and handling 

 have reduced losses in recent 

 years. Good-sized runs returned 

 in 1963. 



Domestic and mining pollution 

 depleted runs before construc- 

 tion of Cottage Grove Dam in 

 1942, which blocked runs 45 km. 

 above mouth. Releases of wann 

 water from the dam prevent use 

 of downstream areas by spring 

 Chinook. 



Little information on extent of 

 former runs. Dorena Dam blocked 

 Row R. in 1949. 



Sandy Hatchery (O.F.C.) rears 

 part of the spring chinook run 

 and the rest spawn in upper 

 watershed.
