We have received your request of November 14, 2003 and payment of $217 for the
renewal of the referenced substitute water supply plan that expires December 31, 2003.
The substitute supply plan accounts for a variable amount of exposed lake surface that
increases from 6.6. acres in April 1998 to an anticipated 18 acres in December 2004. The entire
lake surface was first exposed. after December 31, 1980. Consumptive use of water at the
property consists of evaporation from the pond surface area and water lost in product as shown
in the attached table entitled Glover Analysis Inpuf. No water is needed for dust suppression
associated. with. the wet mining operation. The delayed impacts to the. river are determined
using a Stream Depletion Factor. of 30 days. We agree with the calculations in this table.
The ultimate plan for the source of replacement water is recharge ponds that will be
operated through. an agreement with the Brighton Ditch Company. The recharge ponds, or
sumps,. were. used to recharge water during 1998 and 1999 using wafer diverted when there
was no call on the river. The accretions to the river that resulted from the recharge were
calculated using a Stream Depletion Factor of 280 days. Those accretions are shown in the
attached table entitled Stream Depletion Analysis Using Stream Depletion Factors, dated
November 12,.2003. We agree with the calculations in this table.
Currently, the recharge ponds are not being. utilized pending a final agreement with the
Brighton Ditch Company.. Until the agreement is finalized reusable effluent will be leased from
Consolidated Mutual Water Company (Consolidated) and the St. Vrain Left Hand. Water
Conservancy District (Left Hand).. Water leased from Consolidated, in the amount of 36.87
acre-feet, will be used to replace depletions during the months of April 2004 through October
2004. Of the. 36.87 acre-feet of lease water from Consolidated,. approximately 3.2 acre-feet will.
cover transit losses (9.5% based on 0.5% per mile for 19 miles).. Water leased from Left Hand,
in the amount of 11.48 acre-feet, will be used to replace depletions during the months of
January 2004 through March 2004 and November 2004 through December 2004,
I hereby approve this substitute water supply plan, in accordance with Section 37-90-
137(11), C.R.S., subject to the following conditions:
1. This plan shall. be valid through December 31, 2004, unless otherwise revoked or
modified. Should a renewal of this plan be needed, a request to renew the plan and
