Biology CDP1 Task 2 Ecosystem: Bear Lake Utah watershed Geographic location of Bear Lake: Bear Lake is located on the border in the North east corner of Utah, and the south east corner of Idaho. People have been coming to bear lake from the earliest times in America. Mountain men held rendezvous there and Indians dwelt near the lake in the warmer months. Bear Lake is a natural lake, and the northern swampy grassland area is a refuge for all kinds of birds. The lake is about 20 miles long and 8 miles wide. Lake levels and size vary because of heavy agricultural use, and in years of drought. The border of Utah and Idaho goes right across the center of the lake. The lake is 250,000 years old and is formed by Fault Subsidence, which continues today making the lake deeper on the East side.

Abiotic Factors (non-Living) components of an ecosystem: * Fault Subsidence – Giving the lake its extreme depth and continued progression. * Dike in place on Idaho side of lake to prevent annual flooding, forces water to move to other areas. * Lime stone deposits in the lake, float and make it a striking blue color.
