1. Chicago. Burlington & Ouincy Pipeline. This water right is an extremely small
direct flow right. The initial appropriation was for .15 cfs. Originally, 0.0214 cJ's
were used for domestic and irrigation purposes and 0.1286 cfs were used for
consumptive power purposes in connection with a railroad operation. The Town
of Lyons acquired the 0.1286 cfs industrial right, but has not changed the right to
municipal use.

2. St. Vrain & Palmerton Ditch. The St. Vrain & Palmerton Ditch is owned by a
mutual ditch company. The water rights were originally adjudicated as direct flow
rights for irrigation purposes. Lyons has acquired 1.5 shares of stock in the SI:.
Vrain & Palmerton Ditch Company. However, the Town has not changed its pro
rata share of the water rights to municipal use. At this time, there has been no
historic consumptive use analysis of the Town's shares. Based on previous cas(~s
involving changes of St. Vrain & Palmerton Ditch water rights to municipal usei;,
1.5 shares would typically yield 36.9 acre-feet of annual yield.

3. Button Rock Reservoir. Lyons is entitled to the first 300 acre-feet of the senior
storage right in the reservoir. Lyons also has carry-over rights up to a total 300
acre-feet cap comprised of carry-over water and water stored in priority.
Additionally, the water commissioner has run an undecreed exchange up to the
Button Rock Reservoir 300 acre-foot pool using the Town's 523 CB-T units as the
source of supply. It is believed that most, if not all, of the Town's 523 CB-T units
were exchanged up to Button Rock Reservoir prior to the Colorado Wat(~r
Conservation Board's filing for in-stream flow rights in the North Fork of
St. Vrain Creek.

The Town will be undertaking within the near future an engineering study to determine
the firm annual yield of its water rights portfolio, and to determine whether it will be necessary
for Lyons to acquire additional water supplies and storage to provide for its future water demand:;.
Based upon the results of the study, the Town will undertake such Water Court adjudications,
water rights purchases, and/or water agreements as may be appropriate.
