At times flow affected by discharge from floodwater-retarding structures controlling runoff from 149 mi² in the Clear Creek watershed. There are no known diversions above station. No flow at times.

EXTREMES OUTSIDE PERIOD OF RECORD - Maximum stage since at least 1880, 36.5 ft in May 1908, from information by Gulf, Colorado, and Santa Fe Railway Company. Flood in May 1935 reached a stage of 34.0 ft, from information by Texas Department of Transportation. Both peaks referenced to present site and datum.
