Width: 5.2    Vel: 1.1    Area: 1.66    Disch: 1.83    G.H.: 1.65
No. Secs: 27    Qm Type: Open    Meter: P-Y281    Wt. Sz:
Meter located ROD ft. above bottom of wt.
Spin test before Qm Free , after Qm Free
Qm plots % diff from rating no.
Control: CLEAR
Weather: Cloudy and cool.
G.H. changed 0.00 ft. in .5 hrs.    Location: WADING 25 ft DS of gage.
Measurement rated Good 5% based on the following conditions:
Flow: Steady, mostly
