Hydrology data from selected Louisiana freshwater forested wetlands 2004-2022

Infinity water level recorders were installed in 2004 to monitor hydrologic conditions in five freshwater forested wetlands in Louisiana: Bayou Chevreuil, Bayou Teche National Wildlife Refuge, Mandalay National Wildlife Refuge, Jean Lafitte National and Historical Park, and Treasure Island. Hourly measurements were collected continuously on a 24- hour basis through April 2022, producing an extensive record of wetland hydrology. The dataset shows daily changes, flooding, and long-term shifts in water levels across the sites. It also provides a foundation for evaluating the impacts of climate variability and extreme events on Louisiana’s freshwater ecosystems.
