Peak-flow frequency information is needed for flood-plain mapping, design of highway infrastructure, and many other purposes across Montana. The USGS Wyoming-Montana Water Science Center has an ongoing project working to update peak-flow frequency estimates at USGS streamgages across the state.
The Montana Department of Natural Resources and Conservation requires peak-flow information for Federal Emergency Management Agency (FEMA) floodplain mapping for various locations across Montana. Accordingly, the USGS WY-MT Water Science Center is in the process of updating peak-flow frequencies across the state using Bulletin 17C (https://pubs.er.usgs.gov/publication/tm4B5) methods. The map below illustrates the status of updates for Montana streamgages. The data for these streamgages are publicly available on the WY-MT WSC Peak-flow Frequency Analyses landing page.
