   at datum 2.67ft lower, used as supplementary gage when flow was less than 4,800 ft3/s.

REMARKS.--Records good above 5,000 cfs, and fair below.
   Since Nov. 7, 1953, slight regulation at low water caused by diversions above control
   0.7 mi downstream from gage by a steam-electric powerplant for cooling of condensers.
