WATER RIGHTS
The Lake Canal Company Reservoir Company has issued 160 shares of water stock which is
presently owned by 46 stockholders. All of the stock is privately owned and used for agricultural
purposes. All the water is delivered to the Lake Canal Ditch by a diversion from the Box Elder
Creek. The Lake Canal Ditch is owned by The Lake Canal Company which is a separate company
from the Lake Canal Reservoir Company. However, all the water stored and delivered from the
Gray Lakes is owned by stock holders in the Lake Canal Company.
The Lake Canal Reservoir Company has historically supplied a portion of the irrigation water for
approxunately 5,200 acres of land. The water for irrigation is supplied by a storage decree from
Box Elder Creek equal to 1,178 acre-feet. The priority numbers, appropriation dates, and storage
right are summarized in Table 1. The Lake Canal Ditch Company, which is separate from the
Lake Canai Reservoir Company, also delivers CBT water and water from Tunanth Reservoir and
Lake Canal Reservoir No. 1.

The company desires to preserve the storage right on this reservoir and is interested in
rehabilitating the dam to allow full storage. At the present tnne, Gray Lake Reservoir No. 3 is
restricted to zero storage by the State Engineer due to the poor condition of the dam and outlet
works. The latest inspection report completed by the by the State Engineer in 1999 is included
in Appendix G. The State Engineer has rated the upstream and downstream slopes, the outlet, the
spillway, and the seepage conditions as poor. These items will have to be addressed to bring the
reservoir to full storage.
