MAJOR SPECIES Pink OTHER SPECIES Chum, coho, trout 
ESCAPEMENT TIMING Early. July-Aug. ESCAPEMENT MAGNITUDE  »>50,000 
SPAWNING FACILITIES Excellent. Gravel riffles throughout accessible stream, broad, clear water, optimum 
current velocities. 
STREAM TEMPERATURES Normal range. Observed ranges: 50-58°F., 1950; 48.5-59°F., 1951; 
51-55°F., 1952; 52-5S°F., 1953. 
VALLEY DESCRIPTION Glacial. Steep valley sides, bedrock upper slopes and ridges. Valley extends N. 6 miles 
to high cirques, short, steep valley on W. side rises to hanging valley with Heart Lake cirque. 
DRAINAGE Greater than 25 square miles. Snowfields, high lakes and ground water. 
STREAM MOUTH IDENTIFICATION The stream is reached by ascending the slough which joins the 
Chickamin River in the upper delta. Stream has long high bar on E. side of outlet with long shallow pools. 
Only clear water tributary on slough. 
TRAILS AND SURVEY ROUTES There isa trail along the N. side of the Chickamin valley which leads to 
Humpy Creek. The creek is easily hiked on normal water levels. Slough is easily navigated by skiff and outboard 
to creek. 
AERIAL SURVEY NOTES Stream easily observed from air. Afternoon light makes W. side of stream preferred 
for reduced reflections. Steep wall on W. side requires above normal altitude for slipping nearly vertically 
down over the stream. 
UPSTREAM 
LENGTH ACCESSIBLE 2 miles AVERAGE WIDTH/DEPTH  50-60'/12-18" 
GRADIENT AND VELOCITIES 1° at 2!' per second 
BOTTOM _ Sand, gravel and small rock. More coarse in upper stream. 
MARKER DISTANCE 2 miles. 
MARKER IDENTIFICATION Impassable falls easily identified. 
BARRIERS _ Impassable falls over bedrock shelf. 
TRIBUTARIES Heart Creek enters . 3 miles below barrier falls from steep W. side of valley. A limited section 
just above its mouth utilized by spawning salmon. 
SCHOOLING AREAS At the confluence with the Chickamin Slough. Schooling salmon in glacial streams make 
use of the contact area of clear and silt water for concealment. Several pool areas up the creek are used to a 
lesser degree on the upstream migration. 
SPAWNING AREAS _ Heaviest spawning concentrations observed from .5 to 1.5 miles upstream on excellent 
spawning riffles. 
GENERAL NOTES This is the second largest spawning tributary known to be in the Chickamin River system.
