River Gauge Data

These hydrographs are from some rivers that experienced flooding from the heavy rains associated with Ian. Some water levels in some of the Central Florida river systems were low due to persistent dry conditions observed across the state. The color code helps identify the intensity of flooding or potential flooding along the river:

The color code helps identify the intensity of flooding or potential flooding along the river:

• Near Flood Stage (yellow) - flooding becomes a concern. River/stream is approaching or is forecast to approach the gage height (flood stage) where flooding is defined to begin. Flood stage is an established gage height for a given location at which a rise in water surface level begins to create a hazard to lives, property, or commerce.
• Minor Flooding (orange) - minimal or no property damage, but possibly some public threat.
• Moderate Flooding (red) - some inundation of structures and roads near the stream/river. Some evacuations of people and/or transfer of property to higher elevations.
• Major Flooding (violet) - extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations.

Select one of the rivers from the interactive and see how the river rose and fell over time. What was the peak crest of the river? How long did it take for the river to crest and return to normal (below the action stage) after Ian passed through the area?
