The Two Rivers National Wildlife Refuge is one of five refuges on the Mark Twain National Wildlife Refuge Complex. The Complex was established in 1958 for the protection of migratory birds, and spans 350 miles along the Mississippi River in the states of Iowa, Illinois, and Missouri.
Two Rivers NWR is located near the confluence of the Mississippi and Illinois Rivers. The refuge includes five divisions - Calhoun, Gilbert Lake, Batchtown, Portage Island, and the Apple Creek Division - totaling 8,500 acres. Two Rivers functions as an important link in the chain of resting, feeding, and wintering areas for birds migrating along the Mississippi Flyway.
More than 200 different species of birds funnel through this important river juncture on their fall migration including over 5,000,000 ducks and 50,000 geese. Open water pools, backwater sloughs, small impoundments, wetland management units, and a cooperative farming program all contribute to this objective.
As with the other refuges of Mark Twain Complex, Two Rivers is a popular area for the once endangered bald eagle, with over 1,000 over-wintering in the area. Two Rivers is also one of the few remaining places where the Boltonia decurrens (decurrent false aster), a federally threatened plant, can still be found.
