MAJOR SPECIES Pink, chum OTHER SPECIES Coho, trout 
ESCAPEMENT TIMING Middle. Aug. -Sep. ESCAPEMENT MAGNITUDE _ >20,000 
SPAWNING FACILITIES Excellent. Limited intertidal riffle areas. Upstream riffles throughout accessible 
stream offer excellent facilities. 
STREAM TEMPERATURES Normal range (Estimated). 
VALLEY DESCRIPTION Glacial origin. Stream cut. Broad valley between two high ridges. Timbered areas through- 
out with scattered muskeg. 
DRAINAGE 70 square miles (Polar Planimeter). Precipitation fed. Part of the drainage is from the W. slope of Mount 
Reid (4,560' elevation), the highest point on Revillagigedo Island. 
STREAM MOUTH IDENTIFICATION Broad intertidal flats with meandering stream course identify Carroll 
River.

during normal water levels. 
AERIAL SURVEY NOTES Excellent aerial visibility. Terminal point and barrier falls easily seen from the air. 
INTERTIDAL ZONE 
LENGTH 1.6 miles AVERAGE WIDTH/DEPTH 80-120'/18-36" 
GRADIENT AND VELOCITIES Less than .5° at 1=2' per second 
BOTTOM Silt, sand, gravel. 
HIGH TIDE LOCATION Above grassflats where stream bends toward W. side of valley. Extensive gravel bar on 
E. bank. Tributary enters just above from E. side. 
SCHOOLING AREAS Numerous large, deep holes throughout intertidal zone. 
SPAWNING AREAS | Riffle areas just below high tide mark. 
GENERAL NOTES Deep holes in the intertidal zone are collecting points for dead salmon prior to flooding. 
UPSTREAM 
LENGTH ACCESSIBLE 2.5 miles AVERAGE WIDTH/DEPTH  80-100'/18" 
GRADIENT AND VELOCITIES Less than 1° at 2' per second. 
BOTTOM Sand, gravel, some boulders upstream. 
MARKER DISTANCE 2 miles. 
MARKER IDENTIFICATION At confluence with large tributary entering from W. 
BARRIERS Barrier falls impassable to salmon in narrow canyon -5 mile above terminal mark. 
TRIBUTARIES Tributary accessible for short distance to salmon enters just above high tide from E. ‘Erminal mark 
tributary accessible to salmon for unknown distance. 
SCHOOLING AREAS Large pools between riffles used by schooling salmon. 
SPAWNING AREAS Riffle areas equally distributed from high tide to terminal mark. 
GENERAL NOTES An excellent spawning stream with a considerably greater potential than observed in recent 
years.
