Know Before You Go

Northern Iowa weather can change rapidly, with windy, sub-zero winter temperatures and hot, humid summers. Tallgrass prairie and wetland habitats provide little protection from the elements, so we encourage visitors to be prepared for the season and to watch weather forecasts. A warm coat, clothing layers, hat, gloves and insulated boots are a must for winter activities. We recommend sunscreen, hat, cool breathable clothing, drinking water and insect repellent for summer visitors.

Visitor Tips

Early morning and evening are typically the best times to observe wildlife because that’s when animals are most active. Waterfowl production areas typically receive less traffic on weekdays - so wildlife are disturbed less frequently during the week. Consequently, weekdays in the morning or evening are usually the best times to visit.


Iowa Wetland Management District provides visitors with year round opportunities to hunt, fish, observe and photograph wildlife, investigate nature or take a hike just to enjoy the fresh air.

Other Facilities in the Complex

Iowa Wetland Management District is managed through the Union Slough National Wildlife Refuge office. Four tracts of Northern Tallgrass Prairie National Wildlife Refuge are managed through the Union Slough National Wildlife Refuge office as well.

Rules and Policies

Each wetland management district wetland management district
A wetland management district is a U.S. Fish and Wildlife Service office that manages waterfowl production areas in one or more counties. Waterfowl production areas are small natural wetlands and grasslands that provide breeding, resting and nesting habitat for waterfowl, shorebirds, grassland birds and other wildlife. The Fish and Wildlife Service acquires waterfowl production areas under the authority of the Migratory Bird Hunting and Conservation Stamp Act, primarily using funds from the sale of Federal Duck Stamps. The Refuge System’s 38 wetland management districts comprise thousands of waterfowl production areas – almost all in the Prairie Pothole Region of the Northern Great Plains.
