Gauge Description:

USGS gauge SF Stillaguamish nr. Granite Falls. The USGS has not recently taken discharge measurements here so there is no stage-discharge curve for this site. On the staff gauge 4.0-4.7 is the lower range of flows and although it's slightly more forgiving some bad sieves open up and pin potential is high. At 5.0-5.8 the river becomes much more pushy but sieve danger goes down--many consider flows of 5.4-5.6 to be ideal. Above 5.8 the river jumps up another notch and becomes even more pushy and strong class V skills are required.
