Logan River, flow and stage at Dewitt Springs

The QC0 file contains the raw pressure, temperature, and depth data collected by an in-situ AquaTroll. The QC1 file contains the quality-controlled depth data and the derived stage and discharge data. The depth data is a measure of the water surface elevation relative to the AquaTroll. The derived stage data is the water surface elevation relative to a benchmark at the site. The discharge data is calculated from the stage data using the relationship established from the site rating curve. The stage-discharge relationship was developed by making measurements of flow and stage under varying flow conditions and thus establishing a relationship between water depth and flow at the site. Flow measurements were made with a YSI Flowtracker handheld ADV using the velocity area method.
