Staff Gage

Look for a boulder on river right just downstream of Willow Creek. A staff gage is affixed to the downstream face.  It is marked in 500 cfs increments and goes up to 5,000 cfs.

Because of the trees growing across the exit from this pool, the gage always reads high, typically by 500 cfs or so.  However, the error may vary from year to year as trees grow bigger in low flow years or get washed out in wet years.

FERC Article 402, required the installation of a staff gage marked in 500-cfs increments at a location downstream of the confluence of Willow Creek and the San Joaquin River.
