Mark Ojibway wades in shallow water looking for walleye during the spring spearfishing season at the Chippewa Flowage on the Lac Courte Oreilles Reservation, Sunday, April 14, 2024, near Hayward, Wis. Walleye numbers in some lakes are dwindling due to warming waters, increasingly variable seasonal changes and lakeshore development. Losing the species would mean losing a food source for Ojibwe and other Indigenous people, a sovereign right to fish and a deep connection to tradition and nature. (AP Photo/John Locher)
