History of human impact on Bear Lake

The immediate uses of the water in Bear Lake, local surrounding streams, and the larger Bear River, were primarily for fishing and irrigation. After building a few aspen cabins, the newly settled pioneers began the task of constructing irrigation canals. Within its valley, the Bear River and its tributaries water over 50,000 acres of land in Rich County. The largest irrigation sources are Big Spring and Swan Creek. Settlers in Laketown, Round Valley, and Meadowville continued to construct a network of canals still being used today; these included the Crawford and Thompson Canal, the Beackwith Canal, and the Chapman Canal (Parson, 1996)...

Paleo-biology and paleo-hydrology of the Bear Lake Basin, Utah

Many ancient clam and snail shells have been found around the shoreline of Bear Lake. Local residents have at times gathered the shells as a source of calcium for their chickens. These shells are well preserved and have been dated to be 10,000 years old (Smart, 1963). Curators at the Smithsonian Institute identified all 6 species of snail and one species of clam. Carbon dating performed by Columbia University estimated shells gathered from the Ideal Beach area of Bear Lake to be 12,000 years old...
