1Gage discontinued in 1970. Peak estimated from high water mark in vicinity of gage structure by extrapolation of rating curve.
2Gage discontinued in 1978. Peak estimated from high water mark in gage structure by extrapolation of rating curve. Peak affected by failure of upstream impoundments. 
*Recurrence interval estimates obtained from FEMA Flood Insurance Study reports 
CFS - Cubic feet per second
CFSM  -  Cubic feet per second per square mile of drainage area
FEMA  -  Federal Emergency Management Agency
POR    -    Period of record is less than 10 years, recurrence interval not determined
Recurrence Interval - average time interval between occurrences of a hydrological event in years
