The USGS in cooperation with several local public and private entities has developed a web-based flood mapping tool to assist communities in visualizing their flood risk based upon the river levels as measured at certain gages. The stations for Fenton and Valley Park were the first two developed along the lower Meramec River.
The Fenton Gage is available for modeling at https://fim.wim.usgs.gov/fim/?site_no=07019210.
The Valley Park Gage is avaiable for modeling at https://fim.wim.usgs.gov/fim/?site_no=07019130.
