Federal Push to Rename Lake Ontario as “Lake America” Gains Traction
By Drooid · · How we work
Renaming Initiative and Federal Implementation
President Donald Trump signed an executive order in late August directing the Interior Department, in coordination with the U.S. Board on Geographic Names, to replace “Lake Ontario” with “Lake America” in federal geographic records. The order cites the lake’s role in American commerce, transportation, defense, and history. The National Weather Service (NWS) confirmed it is “in the process” of updating online maps, weather products, websites, and other materials, working in phases to avoid operational disruptions.
Private-Sector Alignment
The firm’s decision follows the NWS’s rollout, aligning its forecasts with the federal naming standards.
Historical and Geographic Background
Lake Ontario, the smallest of the five Great Lakes by surface area, covers roughly 7,340 square miles, with a deepest point of about 802 feet and an average depth near 283 feet. The lake’s name derives from the Iroquoian term “oniatarí,” often translated as “lake of shining waters,” a designation used by European mapmakers since the 17th century. The lake forms part of the international boundary between the United States and Canada, supporting major ports in Toronto, Hamilton and Rochester.
Local and Political Opposition
Rochester City Council issued a proclamation to continue using “Lake Ontario,” and more than a dozen Monroe County legislators signed a letter opposing the federal renaming. Canadian officials have reiterated that they will retain the historic name in Canada. Map providers have responded variably: Google Maps and Apple have adopted the new name for U.S. users, while MapQuest has declined to change it.
Outlook and Potential Impact
The NWS expects the naming updates to appear across its products in the coming days and weeks. Because the executive order applies only to federal documents, state, local, and private entities remain free to choose either name, creating a mixed naming environment for maps, navigation tools, and public discourse.
