the Minnesota Department of Natural Resources (DNR) made Bde Maka Ska the official name in Minnesota. To change it at the federal level, the state submitted materials to the U.S. Board on Geographic Names, which approved the change in June 2018. Park signs around the lake use only the name Bde Maka Ska. On April 29, 2019, the Minnesota Court of Appeals reversed the decision of the DNR, holding that a name that had been in use more than 40 years could only be changed by the legislature. The MPRB stated they would continue to keep the signage of Bde Maka Ska at the lake and Minneapolis Mayor Jacob Frey said, "I will continue to call Bde Maka Ska by its rightful name. That was the lake's name before people who look like me renamed it to honor a slavery apologist and as far as I'm concerned that is still its name today". The DNR appealed the court decision, and also released a statement confirming that the federal Board on Geographic Names (BGN) had adopted Bde Maka Ska as the lake's official name. Executive secretary of the U.S. Board on Geographic Names Lou Yost said, "State legislation (or court ruling) is not binding on the Federal Government. The name at the Federal level will remain Bde Maka Ska as was approved at the BGN's June 21, 2018 meeting". The Minnesota Court of Appeals decision was appealed to the Minnesota Supreme Court, which heard oral argument November 13, 2019. On May 13, 2020, the Minnesota Supreme Court ruled that the Minnesota Department of Natural Resources had the authority to rename Lake Calhoun as Bde Maka Ska, ruling that the law restricting renaming only applied to county boards, not to the DNR. Wildlife The lake contains black crappie, bluegill, bowfin, common carp, hybrid sunfish, largemouth bass, northern pike, pumpkinseed, tiger muskellunge, walleye, white sucker, and yellow perch. Some fish consumption guideline restrictions have been placed on the lake's bluegill, crappie, largemouth bass, northern pike, walleye, and white sucker due to mercury and perfluorooctanesulfonic acid contamination. In 1991, the then-Minnesota state record tiger muskellunge at was caught in the lake. The Minneapolis Park and Recreation website lists the lake as one of the best in the city for ice fishing walleye, northern pike, and crappies. Zebra mussels, an aquatic invasive species, were found in the lake in 2018. See also List of lakes
