[1] Knott Avenue runs over Fullerton Creek on a small concrete bridge built in 1950.

[3] The highest flow during that period (mouth, at Fullerton) was 1,600 cubic feet per second (45 m3/s) on 14 March 1941.

[3] In that time period, no other flow passed 1,000 second-feet, although it did come close to on 2 March 1938 (the peak of the Los Angeles Flood of 1938).

[3] The creek was originally a natural stream that flowed from Puente Hills in a southwestern direction toward the southeastern borders of the city of Fullerton.

[1] There is a seven-acre (2.8 ha) greenbelt built around a short segment of Fullerton Creek that opened in 1974.
