deep prairie coteau pothole is unusual in that it has forested islands. Over
the past decade, water levels in the slough have risen steadily, doubling the
size of the slough. This has decreased the size of the colonial waterbird
nesting colony on the island, but has created new habitat on the south

Conservation Issues

waters have almost entirely engulfed the original nesting island. This prevents
ground-nesting, and hastens the demise of the resulting flooded timber in which
most of the birds nest. Eventually, the flooded timber will rot and fall down.
Disease is always a concern in a dense waterbird nesting colony.


The water and islands belong to the state.
The land on the east and northeast is state-owned Game Production Area or
School & Public lands. The rest of the land is privately-owned.

Land Use

of the privately-owned upland is used as pasture. The state-owned portion is
managed for upland game production.
