2.2
Lookout Creek’s average discharge is the equivalent of a fully-loaded concrete truck rumbling down the river bed every 2.2 seconds!
Lookout Ck mean annual discharge - 121.83 cubic feet per second (cfs)
A standard concrete truck holds 10 cubic yards or 270 cubic feet (cf).
270 cf ÷ 121.83 cfs = 2.21 s
Concrete trucks appear to be 7.168 m long (google) and if you chained them, bumper to bumper with no space in between, the “train of concrete trucks” would be traveling 7.25 mph.
With a more reasonable following distance of a couple of truck lengths, you’d have a never ending line of concrete trucks moving around 25 miles an hour!
