prlmary fish of Alaska's commercial fishing Industry. These 

 fish, along with steelhead, cutthroat, and dolly varden char are 

 also Important for subsistence and sport fishing. Timber harvest 

 results in the degradation of fish habitat and erodes the $60 

 million per year commercial fishing Industry of Alaska. 



Timber harvesting raises the temperature of the water in 

 streams in the area being cut, a change which can be lethal to 

 juvenile and adult salmon populations. Adverse changes in stream 

 flow also occur. Deficiencies in dissolved oxygen due to more 

 organic matter in the water during timber harvesting also can be 

 lethal to the fish. Stream sedimentation from logging and road 

 construction reduces food supplies and disturbs spawning areas.
