EXTREMES OUTSIDE PERIOD OF RECORD.--
Floods of March 1936 and
September 1938 reached stages of 10.5 and 10.2 ft, respectively, from

PERIOD OF DAILY RECORD1.--
DISCHARGE: October 2012 to current year.
Turbidity data are collected every 15
minutes using an in-situ turbidity probe located in the same pipe
adjacent to the automatic sampler intake tubing. Daily
suspended-sediment load and concentration are derived from a regression
equation relating turbidity to suspended-sediment concentration.
