Choi, N., 2023, Geospatial and model dataset for flood-Inundation maps in a 10-mile reach of the Sabinal River and a 7-mile reach of the West Sabinal River near Utopia, Texas, 2021: U.S. Geological Survey data release, https://doi.org/10.5066/P9CIK9ZF.

Summary

This data release documents the digital data used to produce flood-inundation maps for a range of gage heights (stages) for the Sabinal River near Utopia, Tex. The simulated flood-inundation maps correspond to a range in stage from 11 to 28 feet (ft) at U.S. Geological Survey (USGS) streamgage 08197970 Sabinal River at Utopia, Tex. at intervals of 0.5-ft. The maps were created for a 10-mile reach of the Sabinal River extending from USGS streamgage 08197936 Sabinal River below Mill Creek near Vanderpool, Tex. to USGS streamgage 08197970 Sabinal River at Utopia, Tex. (hereinafter referred to as the “Utopia gage”) and 7-mile reach of the West Sabinal River were created by the USGS in cooperation with the Bandera County River Authority [...]

Purpose

A library of 35 flood-inundation maps at 0.5 ft increments ranging in stage from 11- to 28-ft was prepared for use as a quick reference guide. The map library identifies areas likely to be flooded throughout a range of high-streamflow conditions depending on the stage. Real-time stage data obtained from the Utopia gage can be used to select which flood-inundation maps are of interest during a flood. The flood-inundation maps and HEC–RAS model documented by this data release and its companion interpretive report will be made available as part a flood preparedness toolset for the Sabinal River at the Utopia gage. The toolset is intended to provide emergency management personnel and residents with information to aid with flood response activities such as evacuations and road closures, as well information for use in post-flood recovery efforts.
