Excerpt from Bulletin of the United States Bureau of Fisheries, 1917-1918, Vol. 36 It is the purpose of this paper to direct attention to some little known but very important food fishes in Bear Lake, Idaho and Utah. Aside from their value as food, these fishes are of interest to ichthyologists, as they belong to previously unknown forms that have managed to survive as representatives of an ancient quaternary fauna, which was no doubt composed of numerous species Of relatively wide distribution. At present they are confined to a single small lake, and they therefore remind us of the animals Of certain oceanic islands which have been preserved under favorable conditions, while Others of their kind less favored have long since passed away. Bear Lake is a part of the drainage system of Great Salt Lake, the connection being through Bear River, which has its origin among the mountains of the eastern slopes of the Wasatch Ranges. Through the channel Of its outlet, Bear Lake Was at one time connected with the quaternary Lake Bonneville, the Shore lines of which are still plainly traced along the sides of the bordering mountains. The outlet of Lake Bonneville carried its overflow into Snake River, and thus Bear Lake was for a time a part of the Columbia River system.
