| Within the Tanana drainage, virtually all spawning takes place in the north-flowing streams draining the north side of the Alaska Range. Clearwater Creek, near Big Delta, is probably the greatest producer of coho salmon in this group of rivers. Reports of coho in streams above the Tanana, for example in the Chandalar River and various tributaries of the Porcupine River may be valid. However, both coho and chum are known as silver salmon in interior Alaska. Since the chum is one of the most abundant fish in the area, these reports of silver salmon far up the Yukon need to be viewed with some skepticism until verified (Ref. 27547). |
