Flow from the Trinity River to Galveston Bay

The flow of the Trinity River into Galveston Bay varies naturally over a very wide range. Naturalized flows, which remove man-made influences from measured flows by subtracting the effects of reservoir evaporation and storage, diversions, inter-basin transfers, return flows, and run-off rates due to land uses, have been calculated for the Trinity basin by several parties. These are reviewed and compared as they relate to Galveston Bay. The analyses cover the period from the 1940s to the 1970s and 1980s on a monthly basis.
