Because the North American river otter lives both on the land and in the water, it is the perfect ambassador species for Friends of the Chicago River as we strive to reach the goal of a first-class environment for the people, plants, and animals that share it.

Highly social, playful, and possessing seemingly unlimited energy, otters are a joyful sight to the lucky observer, and a returning otter is an indisputable sign that the Chicago River is making great strides in its recovery. Yet the river otter is highly sensitive to environmental pollution, relying on the river for hunting, frolicking, traveling, and as a refuge from danger, so clean water and healthy habitats are essential. The Chicago-Calumet River system is not yet a preferred home for the river otter. A pinnacle species in the food chain, river otters exemplify the need for comprehensive and continued river restoration and improvement, benefits that will greatly impact people, too. 

Supporting Friends in our efforts to improve the Chicago River, members of The Otter Society are those individuals and businesses that make a generous annual commitment to Friends of the Chicago River to continue the renaissance of this great natural resource. Choosing to invest in the thoughtful restoration and revitalization of the Chicago River and its watershed and making it a priority in one's philanthropy works to ensure that the renaissance will robustly continue and the river otter will return.
