USGS - Irma High Water Marks

During and after Hurricane Irma, the US Geological Survey recorded high water marks across the affected area, as they do for every major storm [https://www.usgs.gov/special-topic/hurricane-irma]. The files in this dataset provide 506 high water marks for Hurricane Irma flooding, and 202 peak sites. These files were downloaded following the steps below. If you'd like to check the original sources again, or search for HWM for a different storm, you may find these directions helpful.

The High Water Marks can also be visualized directly from the USGS Flood Event Viewer for Irma [https://stn.wim.usgs.gov/fev/#IrmaSeptember2017]
