The status of the Dolly Varden Salvelinus malma population overwintering in the Wulik River drainage of northwestern Alaska was investigated during 1994-1995. Population abundance, and length composition were estimated. The number of Dolly Varden over 399 mm in FL overwintering in the Wulik River during the winter of 1994 - 1995 was estimated at 361,599 fish (SE = 62,306). Two aerial surveys conducted during the last week of September 1994 counted 66,937 fish and 65,100 fish respectively. It was assumed that the late migration of Dolly Varden into the Wulik River in 1994 accounted for much of this difference. Dolly Varden ranged in fork length from 250 to 826 mm with the majority (79%) between 400 mm and 500 mm FL. Scars from attempted predation by marine mammals were noted on 887 (20.7%) of fish inspected.
