Daily Water Surface Elevation Maps for the Everglades

Daily continuous water surface elevation maps for the freshwater Everglades are generated from a network of over 200 automated stage monitoring gages. The dataset provides spatially interpolated surfaces in centimeters relative to NAVD 88, with records beginning on January 1, 2000. The project is managed by the EDEN network and integrates telemetered gage data with a high-resolution ground elevation model.

Use Cases

• Model daily water depth across the Everglades by subtracting the ground elevation model from the provided water surface elevation layer.
• Analyze long-term trends in wetland inundation using the daily time-series of water surface elevation values.
• Calibrate hydrological models with spatially continuous water surface data interpolated from over 200 gage stations.
• Study correlations between water surface elevation dynamics and changes in specific biotic communities within the wetland ecosystem.

Strengths

• Data collection relies on a network of over 200 real-time, telemetered water level gages.
• Provides daily, spatially continuous surfaces, overcoming limitations of traditional field measurements.
• Long-term temporal coverage with records beginning January 1, 2000.

Limitations

• Spatial coverage is limited to the freshwater greater Everglades region.
• Data accuracy is dependent on the interpolation method and the density of the gage network.
