AUTO DRIVING TOUR STOP #4
On Both sides the road here is McDonald Marsh, named after the former owner of the land. These two marshes were constructed by building dikes in the flood-prone fields. Runoff from surrounding lands fill the marshes. Water can also be added from the creek when needed for management purposes. Refuge staff raise and lower water levels in many marshes and moist soil units to provide habitat for shorebirds and waterfowl food plants.
