Lake Calhoun is officially off the map.
The federal government's approval of its name change was the last hurdle needed for the body of water in south Minneapolis to be recognized by its original Dakota name: Bde Maka Ska.
It also ends a yearslong controversy propelled by the national movement to remove monuments tainted by racism. The lake's former namesake was an ardent supporter of slavery.
"What this means is that any maps created by the government will say Bde Maka Ska instead of Lake Calhoun," said Robin Smothers, a spokeswoman for the Minneapolis Park Board, which also pushed for the change.
The Minnesota Department of Natural Resources approved the name change in January. The U.S. Board of Geographic Names put its stamp of approval on the change last month.
Carly Bad Heart Bull, a descendant of Cloud Man, a Dakota leader of an agricultural settlement at the lake in the 1830s, called it a name restoration rather than a change.
"For so long the indigenous stories of this land have been silenced at least to the broader community," Bad Heart Bull said Monday "It's time for our language, our stories as Dakota people, as indigenous people of this land be lifted up, acknowledged and celebrated."
The U.S. Board on Geographic Names is a federal body created in 1890 to maintain uniform geographic name usage throughout the federal government.
