The Real-time Storm and Flood Data Map contains current warning information from the National Weather Service, live radar and lightning strike data, 1-hour storm track projections, and rainfall and stream level measurements from the ALERT System.

Find out if you live or work near a floodplain, areas identified as having high risk for flooding. Visit our floodplain map to view approximate floodplains. Mapped floodplains have a quantified risk of flood.

Stream Management Corridors (SMCs) represent the space needed to allow a stream to function in a way that replicates natural processes to the extent possible. Stream Management Corridors should be considered when developing a site plan.

The idea of a regional flood control district came after a devastating flood on the South Platte River in 1965. See historic floodplain boundaries, approximate flooding extents (1965), and estimated rainfall (in) related to the flooding event.

The Colorado Association of Stormwater and Floodplain Managers (CASFM) leads an annual water quality field trip. We board a 55-passenger bus and visit good examples of water quality. This Story Map consists of locations and photos from our journeys.

Story map highlighting floods in the Front Range, with emphasis in Boulder CO dating back to the 1840’s. These flood events are considered noteworthy for loss of life, extent of property damage, and other unusual circumstances.

The Fluvial Hazard Zone (FHZ) is the area a stream has occupied in recent history, may occupy, or may physically influence as it stores and transports water, sediment, and debris. Fluvial Hazard Zone mapping represents a step forward in adaptively managing stream corridors, preparing for and mitigating flood impacts, and making informed land use decisions based on an awareness of fluvial processes.
