Summary

The U.S. Geological Survey (USGS) worked in cooperation with the Federal Emergency Management Agency (FEMA) to document the August and September, 2017 Hurricane Harvey storm event in southeastern Texas and southwestern Louisiana. Hurricane Harvey was the most significant rainfall event in United States history in scope and rainfall totals since rainfall records began during the 1880s. From August 25 through September 1, 2017, some areas in southeastern Texas received more than 60 inches of rain; large areas received more than 40 inches of rain. This data release contains the flood inundation polygons, flood-depth rasters, mapped boundaries, and high-water mark (HWM) locations for the selected river basins, coastal basins, and coastal [...]

Purpose

This data release documents high water mark and other flood inundation data collected during August and September 2017 in southeastern Texas and southwestern Louisiana in the aftermath of record amounts of rainfall resulting from Hurricane Harvey. Flood documentation maps were created from the data documented herein by using GIS to show the extent of inundation along impacted river reaches in southeastern Texas and parts of southwestern Louisiana. Data used to determine flood-peak magnitudes and create flood-inundation maps and other flood-inundation products for areas flooded in southeastern Texas and southwestern Louisiana are provided for five heavily flooded major river basins primarily in Texas, six smaller coastal basins, and coastal areas in Texas from Port Aransas to Matagorda Bay. Digital datasets of the inundation area, modeling boundary, water-depth rasters, and final map products are provided.
