    • Cross Lake Flood Map Files

    Metadata Updated: January 19, 2026

    Heavy rainfall occurred across Louisiana during March 8-19, 2016, as a result of a massive, slow-moving southward dip in the jet stream, which moved eastward across Mexico, then neared the Gulf Coast, funneling deep tropical moisture into parts of the Gulf States and the Mississippi River Valley. The storm caused major flooding in north-central and southeastern Louisiana. Digital flood-inundation maps for Cross Lake near the community of Shreveport in Caddo Parish, LA was created by the U.S. Geological Survey (USGS) in cooperation with Federal Emergency Management Agency (FEMA) to support response and recovery operations following a March 8-19, 2016 flood event. The inundation maps depict estimates of the areal extent and depth of flooding corresponding to 7 High Water marks (HWM) identified and surveyed by the USGS following the flood event. First release: November 2016 Revised: September 2017 (ver. 1.1) Additionally, there is a revision history text file called "September_2017_Revisions" available on the main page that explains exactly what changed in the revision.
