Warning About Bookmarks
Please do not bookmark any pages after launching the map. The interactive maps on this site are created dynamically with the most current information available each time you visit them. Using a bookmark (sometimes called 'favorites' depending on the web browser you are using) will bypass certain necessary hidden pages that look for and load this information into the maps.

This means that the most current information may not be displayed correctly to your computer causing the map to look broken or not display at all. Also, the page names within the mapping application may change / disappear without notice causing bookmarked pages to fail or otherwise display undesired results. If this happens to you, close your browser and restart the map from the launch page.

Map Features

Created to assist our Land & Resource Department in the management of our extensive lake system, included is the Department of Natural Resources identifier, water acres, perimeter length, and classification.

Instead of the common blue, the lakes and rivers are colored based on their representative use class – which represents what kind of development and specific land use rules are in effect with respect to that particular body of water.

The map also includes an exaggerated shaded relief map called "terrain" The background colors are a color representation of elevation, as used in the national geographic atlas series maps. For example, blue is used to indicate low elevation and red to white indicates high elevation. Otter Tail County exhibits a uniquely complex range of topographic features visible within its boundaries. This scheme allows for easy classification and identification of the various landforms visible here.

National Wetland Inventory
Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. For purposes of this classification wetlands must have one or more of the following three attributes:
  1. At least periodically, the land supports predominantly hydrophytes
  2. The substrate is predominantly undrained hydric soil
  3. The substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season of each year.
