Rating 8.0 is a good representation of the stage-discharge relationship using clear control measurements. There is a break in the trend below 59.6 ft that won't be honored until lower flow definition is obtain again and confirms this break in trend. If stages receed to this level a measurement should be obtained. The upper end is defined by the newly made measurement no. 1164. The slope begins to increase at 63.70 ft as the water begins to go into overbank conditions on the left bank as indicated by the slop eof 2.03 ft.
