Big Lake National Wildlife Refuge
Big Lake National Wildlife Refuge was created in 1915 by President Woodrow Wilson after local residents became concerned that agricultural interests were destroying the natural environment of the area. It is situated 2 miles east of Manila, Arkansas. 5,000 acres (20 km²) of Big Lake is classified as a National Natural Landmark and 2,100 acres (8 km²) are classified as wilderness. The refuge consists of 5,250 acres (21 km²) of swampland, 2,600 acres (11 km²) of open water, 2,100 acres (8 km²) of bottomland hardwoods, 3300 acres (13 km²) of marsh, and 282 acres (1 km²) of other types.
The refuge was once a portion of the Mississippi River but now the Little River flows through the refuge. A large network of man-made ditches in the Missouri bootheel region drain 2,000 miles (3,000 km) of farmland through the refuge. This non-natural drainage adversely affects the refuge itself.
