Summary

Total dissolved solids (TDS) in surface waters affect water quality and useability and are of particular concern in the Colorado River Basin. Estimates of current and past TDS concentration and flux in rivers support appropriate management and salinity control measures. In this study we estimated the total dissolved solid concentration and flux at 11 sites on tributaries of the Colorado River, starting as early as 1938 until 2021. Of these sites, eight were not affected by dams. For these we estimated daily and water year flow normalized TDS concentration and flux using the Weighted Regressions on Time Discharge and Season (WRTDS) water quality modeling framework. For the three sites situated below dams, we used flow-weighted concentrations [...]

Purpose

This data supports investigation into controls on salinity in the Lower Colorado River Basin, and provides context for trends observed in the Upper Colorado River basin and along the main stem of the Colorado River Basin. This work supports decisions about salinity mitigation and deepens our understanding of processes driving river water quality.
