Two Rivers National Wildlife Refuge was established in 1958 to protect and enhance habitat for migratory birds. Located between the Mississippi River and Illinois River, the refuge encompasses 9,225 acres of riverine and floodplain habitat scattered around the confluence of the rivers. The mosaic of wetlands, open water, bottomland forests and prairies provide habitat for numerous mammals, amphibians, reptiles, fish, nearly three hundred bird species, and a population of decurrent false aster, a Federally threatened plant species.

Swan Lake Drawdown (updated Aug 22, 2024)

Recently the refuge started pumping the water out of Lower Swan Lake.  This is done occasionally by refuge staff to remove most of the water from wetland management units to encourage the growth of annual plants that produce significant amounts of seed.  This seed becomes food for waterfowl in the fall and winter.  The drawdown also creates lots of mudflat areas for shorebirds, wading birds, and others looking for insects in the mud.

When this happens the area is not suitable for canoeing, boating, or kayaking. However, the Middle Swan Lake portion is still accessible from Jan 1 - Oct 15 for boating at the Blooms Landing Access, at the end of Bimms Rd.

If you have any questions, please contact the refuge headquarters at 618-883-2524.
