The school district boundaries in St. Charles County, MO.

Digital flood-inundation maps for a 9.9-mile reach of Dardenne Creek, St. Charles County, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with St. Charles County, Missouri Department of Transportation, and the cities of O'Fallon and St. Peters, Missouri. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Program at http://water.usgs.gov/osw/flood_inundation/ , depict estimates of the areal extent and depth of flooding corresponding to select water levels (stages) at the USGS streamgages 05514860 Dardenne Creek at Old Town St. Peters, Missouri, and 05587450 Mississippi River at Grafton, Illinois. Near-real-time stages at these streamgages may be obtained from the USGS National Water Information System database at https://doi.org/10.5066/F7P55KJN or the National Weather Service Advanced Hydrologic Prediction Service at https://water.weather.gov/ahps2/hydrograph.php?wfo=lsx&gage=drcm7 (USGS streamgage 05514860) and https://water.weather.gov/ahps2/hydrograph.php?wfo=lsx&gage=grfi2 (USGS streamgage 05587450), which also forecasts flood hydrographs at these sites. Flood profiles were computed for the Dardenne Creek stream reach by means of a one-dimensional model for simulation of water-surface profiles with steady-state flow computations. The model was calibrated using the current stage-discharge relation at the USGS streamgages 05514840 Dardenne Creek at O’Fallon, Missouri, and 05514860 Dardenne Creek at St. Peters, Missouri, and documented high-water marks from the flood of December 2015. Stages in the lower Dardenne Creek can be influenced by backwater from the Mississippi River, therefore, 23 sets of water-surface profiles ranging from 18 ft to 40 ft were developed and referenced to the USGS streamgage 05587450 Mississippi River at Grafton, Illinois. The upper stage for each map library exceeds the stage corresponding to the estimated 0.2-percent annual exceedance probability flood (500-year recurrence interval flood) at the streamgage locations. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from light detection and ranging (lidar) data having a 0.26-ft vertical accuracy and 0.71-ft horizontal resolution) to delineate the area flooded at each water level. The availability of these maps, along with information regarding current stage from the USGS streamgages and forecasted high-flow stages from the National Weather Service, will provide emergency management personnel and residents with information that is critical for flood mitigation, preparedness and planning, flood-response activities such as evacuations and road closures, as well as for post-flood recovery efforts. The depth grid data are provided in Tagged Image Format Files (.tiff) and compressed into a .zip archive that is named DardCr_bckwtr_depthgrids.zip.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). In addition to the preceding, required text, the Abstract should also describe the projection and coordinate system as well as a general statement about horizontal accuracy.
