Big Creek Gate Cabin Staff Gauge
Manually recorded stage height
("depth") of Big Creek as measured at the staff gauge
near the Big Creek gate cabin. This staff gauge station has been
extremely stable from year to year. A reading of 1' corresponds
to zero flow, approximately. This gauge was installed in 1986
by Matt Kondolf of UC Berkeley. A reading of 1.4' corresponds
to a flow rate af about 6 cf/s, and a reading of 1.98' corresponds
to a flow of about 42 cf/s (see depth/flow
page). At a reading of 4' the creek is approximately 20' wide
and moves at about 7 miles/hr. We have data going back to 1986.
We also have automated data for several years in the early 90's.
