This data represents waterbodies where freshwater jellyfish have been found. These invasives may be found in other waterbodies, but their presence has not been confirmed outside of the waters listed here. Monitoring is conducted on Wisconsin's lakes and streams in the summer months, with the presence lists compiled in the fall.
