Continuous stage and temperature data were collected via commercially available, unvented and vented submersible pressure transducers (PTs) as ‘tiered’ gages co-located with United States Geological Survey reference gages in relatively small, low-order streams across the United States. Tiered gage data were compared with reference gage records to assess sensor performance variability across different installation methods, reaches, watersheds, and streamflow conditions. Sensor error was evaluated via differences between reference and tiered stage values through time and across variations in atmospheric pressure, barometer proximity, and water temperature. Finally, stage measurements from tiered and reference gages were used to estimate discharge and comparative accuracies evaluated. When installed and visited regularly with tape downs and levels, tiered gages can be pretty accurate! How accurate you ask? Well, please stop on by to see our presentation.
