The Lake America Act would rename Lake Ontario to "Lake America." The bill would apply to all federal documents, maps, regulations, and records, which would be updated to reflect the new name. The Secretary of the Interior, working through the Board on Geographic Names, would oversee implementation of the renaming across federal agencies. Each federal agency would be required to update its documents and maps within 180 days of the bill becoming law. The legislation does not authorize any new funding or establish significant operational changes beyond updating federal records to use the new name.
