REMARKS - Several small diversions above station. Flow is affected at times by discharge from flood-detention pools of 32 floodwater-retarding structures with combined detention capacity of 39,200 acre-ft. These structures control runoff from 200 mi² in the Turkey Creek and upper Pecan Bayou drainage basins. Historically, these retentions are assumed to affect flows by 10 percent or more.

A floodmark surveyed from the flood of Jan. 21, 1968 reached a peak of 24.1 ft. Flood of 1957 was 25.5 ft. on right bank about 0.5 mi. downstream according to local resident, Mr. Eubank.
