Chatcolet Lake is a small area at the southern tip of Coeur d/Alene Lake in Northern Idaho. It was once a lake by itself, but a dam has turned it into part of the bigger, better-known Coeur d/Alene. Chatcolet has the added feature of having a river in its midst; the beautiful St. Joe. The river was expected to become just a part of the lake, but it refused to die and its tree-lined banks clearly outline its path through the center of the lake.
