on left bank at downstream side of bridge on Laurer Road, 0.8 mi northwest of Pleasant Hill, 2 mi downstream from

PERIOD OF RECORD.--October 1916 to September 1928, October 1934 to current year. Monthly discharge only for some 
periods, published in WSP 1305. Gage-height records collected at same site March 1922 to December 1963 are 
contained in reports of the National Weather Service.
REVISED RECORDS.--WSP 523: 1917. WSP 1305: 1920(M). WSP 1908: Drainage area.
GAGE.--Water-stage recorder. Datum of gage is 846.73 ft above sea level. Prior to Dec. 23, 1934, nonrecording gage 
at same site and datum.
REMARKS.--Records good except for estimated daily discharges, which are poor. Sediment data collected at this site.
COOPERATION.--Gage-height tapes and 8 discharge measurements furnished by Miami Conservancy District.
EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of March 25, 1913, reached a stage of 17.5 ft. Discharge at site about      
3 mi upstream, 51,400 ft3/s, computed by Miami Conservancy District. This stage is not comparable with present 
gage heights because of failure of levee in 1913.
