Natural Features Description:
Otter Slough is a small remnant of the former oxbow lakes and associated swamps that once were extensive throughout the Mississippi Lowlands prior to widespread artificial drainage efforts beginning in the late 19th century. Here you can catch a glimpse of what was once an amazing watery wilderness in Missouri’s southeast corner. Water tupelo and bald cypress dominate the trees in the swamp. Both are adapted to living with waterlogged soils. However, periodic drawdowns of Otter Lake creating mudflats are needed for a few years in a row to allow the seedlings of the tupelo and cypress to germinate and grow large enough to survive another round of flooding. The seeds of both water tupelo and cypress float and are readily carried by floodwaters.
This wetland environment is good habitat for a variety of reptiles and amphibians including green treefrog, common snapping turtle, southern painted turtle and the broad-banded watersnake. The waters of the slough support a number of fish species at the northern edge of their range, including the flier, slough darter and the banded pygmy sunfish. Other animals using the swamp include wood duck, great blue heron, green heron, muskrat, and swamp rabbit.
