Fort Wayne grew where the St. Joseph and St. Marys rivers join to form the Maumee, which carries water on to Lake Erie. Flat terrain, river banks and standing water give mosquitoes and rodents plenty of room.
Fort Wayne, the seat of Allen County in northeastern Indiana, counted 263,886 residents in 2020. It sits at about 758 feet, roughly 18 miles west of the Ohio line, and covers around 110.8 square miles of mostly flat ground. The St. Joseph and St. Marys rivers meet at the city's founding site to form the Maumee, and the land east of the Fort Wayne Moraine was once part of the Great Black Swamp.
Residents describe the city in four quadrants split by Calhoun Street and the rivers. The climate is humid continental, with hot, wet summers and cold winters: July highs average about 84 degrees, and snowfall runs near 33.5 inches a year. Damp summers help mosquitoes breed along waterways, and long winters drive mice and beetles indoors.
