Located just 25 miles southwest of Peoria along U.S. Route 24, Banner Marsh State Fish and Wildlife Area is a sprawling 4,363-acre haven for outdoor enthusiasts and wildlife alike. Guarded from the Illinois River by a major levee, this expansive complex of freshwater marshes, lakes, grasslands, and shrublands serves as a vital ecological anchor in Fulton County.
A Unique Landscape with a Rich History
The story of Banner Marsh is one of remarkable environmental resilience and reclamation. Historically functioning as a highly productive bottomland lake and marsh system inextricably linked to the Illinois River, the land underwent drastic changes throughout the 20th century. It was initially drained to create fertile agricultural land and later heavily strip-mined for coal operations.
In the 1980s, the Illinois Department of Natural Resources (IDNR) acquired the property with a grand vision. Partnering with the U.S. Army Corps of Engineers, a massive reclamation project was completed in 2003. Today, the scarred earth has been transformed back into a thriving, optimized wetland habitat that serves a dual purpose: providing exceptional wildlife conservation and improving flood control for the surrounding region.

State species such as largemouth bass, bluegill, crappie, and channel catfish are plentiful, drawing fishing enthusiasts year-round.
Hunting and Dog Training
True to its designation as a Fish and Wildlife Area, Banner Marsh is heavily utilized by hunters during the designated seasons. The area offers managed hunting programs primarily focused on waterfowl, capitalizing on the site’s rich wetland environment. Additionally, the expansive grasslands and open areas provide excellent designated zones for dog training, a popular activity among local sporting dog owners in the off-season.
Wildlife Observation and Birding
Due to its strategic location along the Illinois River Valley Flight Corridor of the Mississippi Flyway, Banner Marsh has been officially recognized as an Important Bird Area by the Audubon Society. More than 200 species of birds have been documented within the park’s boundaries.
Bird watchers flock here to witness massive migrations of waterfowl in the spring and fall. The area is also a critical habitat for raptors. It is common to spot osprey diving for fish, majestic bald eagles soaring overhead, and short-eared owls quartering low over the grasslands at dusk.
