The Little Maquoketa River is a 29.6-mile-long (47.6 km)[1] direct tributary of the upperMississippi River. The Little Maquoketa River is largely confined to Dubuque County, Iowa, and enters the Mississippi in the rural areas north of Dubuque.
Little Maquoketa River is a put and grow stream for trout, including brown trout. Three inch fingerlings are stocked each year and they reach 9 to 10 inches the first year, 12 to 14 inches the second year and continue to grow from that point on. The river is considered one of the best smallmouth bass and trout fisheries in Iowa.[3][4]
