Water-surface elevations derived from submersible pressure transducers deployed along the Salcha River, Alaska, July-October 2018

Metadata Updated: January 20, 2026

The U.S. Geological Survey deployed seven submersible pressure transducers on the bottom of the Salcha River in July 2018. An additional transducer was left out of the water to correct for barometric pressure fluctuations. At the time of deployment, the bank position near each transducer and the water-surface elevation were measured with real-time kinematic GPS equipment. The transducers collected a depth measurement every 15-min until the recovery of five of the seven in October. We adjusted the water elevation measured at deployment by the difference between the depth measured at deployment and each subsequent depth measurement to derive the water-surface elevation at 15-min intervals. The data included as part of this release include the horizontal location of the five transducers and water-surface elevation at the time of deployment. In addition, the date, time, water temperature, barometric pressure control reading, barometric pressure compensated depth measurement, and computed water-surface elevation are reported for each recovered transducer.
