Smelly. Water colour brown to clear, changing rapidly. Scary!
Wetted width 20cm
Pipe inclination 2 deg
Wetted depth 13m
Measurements taken from sampling cup; attempted to measure conductivity by holding meter in the stormpipe flow and then at holding it in pool where the flow contacted the pool, but in both cases, the value kept changing due to micro movements of the meter (I was unable to hold it completely still).
Turbidity not measured in secchi tube, but water column completely clear.
