MAJOR SPECIES Coho OTHER SPECIES Pink, chum, trout 
ESCAPEMENT TIMING Late. Sep. -Oct.-Nov. ESCAPEMENT MAGNITUDE Unknown 
SPAWNING FACILITIES Spawning grounds in the streams tributary to Hall Cove are concealed by the amber 
colored water commonly found on Duke Island. Preliminary examination from the air indicates that conditions 
are most favorable for coho which have been observed in good numbers in most of the tributary streams. 
STREAM TEMPERATURES Warm range (Estimated). 
VALLEY DESCRIPTION Except for the relatively high mountain on the S. side of Duke Island, the entire 
island is flat, muskeg. Geologic reports show that most of the flat island areas contain large quantities of low 
grade iron ore. 
DRAINAGE Flat muskeg area drainages with deep amber color, flowing through small lakes and many small ponds. 
STREAM MOUTH IDENTIFICATION Hall Cove is entered from the S. W. side of the island over shallow 
bars.
