Metadata (Data about data or how the map was made)

River otters are found along rivers, streams, and lakes and also in estuaries, coastal bogs, and large marine waterways such as Puget Sound and the Strait of Juan de Fuca. In the central basin, they are apparently limited to large rivers, such as the Columbia, Yakima, and Walla Walla.

This range model was limited to mapped water and wetlands because smaller water bodies and wetlands are less suitable for River Otters. So some of the smaller rivers and wetlands suitable for breeding otters are not indicated.
