Floodplain Mapping Projects

Middle Smoky Hill Custom Watershed


The Middle Smoky Hill Custom Watershed Floodplain Mapping update project will produce Base Level Engineering (BLE) floodplains for the entire custom watershed. They are beginning to be produced and should be available in Spring 2021. Enhanced data development is anticipated to begin in 2024 for the areas that will undergo a regulatory update. We anticipate regulatory updates for Ellsworth County, but Discovery meetings will be held to discuss where regulatory updates are needed. Ellis County is being updated as part of a separate county-wide project. This website will be updated with relevant content as the project moves forward.
