Summary

This dataset features inundated areas at discharges from 15,000 cfs to 100,000 cfs. The spatial extent for floodplain inundation modeling in the lower Trinity River was from Romayor, Texas, to approximately Moss Bluff, Texas. River sections were modeled using steady flow conditions. For the upper section, discharge and stage were both available for the two gages (Romayor USGS 08066500 and Liberty USGS 08067000). For the lower section, the Moss Bluff gage (USGS 08067100) is tidally-influenced, so gage height didn’t correspond to upstream changes in discharge. To model river stage specific inundation for the upper section, discharge for each Landsat 8 overpass date was entered as the upstream condition and the corresponding water surface [...]

Purpose

This data helps to provide a robust basis for management recommendations such as: river flow recommendations for increasing connectivity with important spawning areas; water level manipulation (e.g. reconnection of areas important for spawning or juvenile development to the main river under conditions other than flooding, such as high flow pulses); and/or terrestrial land management (e.g. maintenance of appropriate land cover suitable for spawning) on private and public lands for conservation of Alligator Gar populations, with links to other target species.
