Figure 2. Flow records for USGS streamflow-gaging station 14400000, Chetco River near Brookings, Oregon. (A) Estimated and observed annual peak flows for water years 1932–2008. (B) Mean daily discharge for water years 1970–2008. Annual peak flows measured for water years 1971–2008, estimated for 1964 on basis of high water mark and extension of rating curve, and estimated for all other years using data from Smith River USGS streamflow-gaging station (11532500) in northern California. Estimates from Smith River record were determined by regression of log-transformed values from period of overlap for which log Chetco River Q_peak = 0.6337 × (log Smith River Q_peak) + 1.4708 (r = 0.83).
