See the Global Flood Inundation Map Repository (GloFIMR) portal (based on Google Maps) here. GloFIMR includes the USFIMR maps.
The USFIMR project commenced in August 2016 with funding from NOAA. The project’s main goal is to provide high-resolution inundation extent maps of past U.S. flood events to be used by scientists and practitioners for model calibration and flood susceptibility evaluation. The maps are based on analysis of Remote Sensing imagery from a number of Satellite sensors (e.g. Landsat, Sentinel-1) with some ground proofing based on secondary sources (e.g. news reports, social media). The maps are accessible via the online map repository below. The repository is currently under development and new maps are added on a weekly basis. For information, requests and data contribution contact the project PI: Dr. Sagy Cohen (sagy.cohen@ua.edu) or Lead Developers: Dinuke Munasinghe (dsnanayakkaramunasinghe@crimson.ua.edu), Austin Raney (aaraney@crimson.ua.edu)
(formerly Bradford Bates and James Misfeldt ).
Flood inundation maps are listed on the map side panel 
and at the table below.
Flood layer properties and download links* will be listed once a layer is selected from the side panel or the map.
* Download links will not work when using ‘Safari’ web browser
The dataset can also be accessed directly via Google Maps, ArcGIS Online or through the SDML Datasets Portal.
Download the entire USFIMR in Shapefile format.

“This dataset was developed by the Surface Dynamics Modeling Lab (PI: Sagy Cohen) under a Subaward with the University Corporation for Atmospheric Research (UCAR) under Cooperative Agreement No. Z16-23487 with the National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce (DOC). The statements, findings, conclusions, and recommendations are those of the PI and do not necessarily reflect the views of NOAA, DOC or UCAR.”
