Exhibit G CMLRB 112 Permit Application
Agile Stone Systems, Inc.
• conductivity (K) values, measured aquifer thicknesses, and monitoring well flow
test rates. From sieve analyses of site aquifer materials plus type curves (Driscoll,
1986, p.786), K values ranging from 2,000 to 12,000 gpd/ft2 can be expected.
4) Aquifer thickness ranges from 0' at its edges, to about 26' in the eastern
monitoring well; an average thickness of 10 to 15' results. Airlift tests of the
monitoring wells resulted in flow rates of about 15 gallons per minute (gpm) in
the western well and 50 gpm in the eastern well. Assuming draw downs of 1 to 2'
in the tests, T values of 30,000 to 50,000 gpd/ft are estimated from the
relationship T _ 2000 x Q/s. (More recent, un-utilized tests, indicate a 60 gpm in
another eastern well with no draw down resulting. Contract Driller Test Results,
12/97)
4.4 Replacement Water
To replace the consumptive water uses in its Project, Agile acquired 5 shazes of Twin
Lakes Reservoir & Canal Company water shazes which closed on November 11, 1997. A
copy of stock certificate # 8311 for the 5 shares is attached.
Twin Lakes Reservoir & Canal Company water share yields have historically ranged
from 0.26 to 1.76 acre-feet per share, with an average of 0.99 to 1.00 acre feetishare.
Subsequent analysis by the SEO indicated that 0.93 to 0.95 acre feeUshare is an
appropriate range to use, and Mr. Van der Horst of the SEO recommended that 0.93 acre
feetfshare be used.
An acre foot has 325,853 gallons. Five shares of Twin Lakes water has an average yield
of 1,515,216.5 gallonslyeaz (0.93 acre feetlshare x 5 shares x 325,853 gallons/acre foot).
Mr. Van der Horst noted that the loss factor in transport is 0.07% per mile. Mr. Dale
S[raw of the SEO Pueblo office noted that Canon City's water in take is 105.57 miles
from Twin Lakes Reservoir. Pazkdale is about 12 miles upstream from Canon City.
Assuming 93.57 miles to Pazkdale, there would be a 6.5% transport loss.
After accounting for water transport loss at 6.5%, an equivalent per-share volume is
about 0.8696 acre-feet, as shown in Table 1. Thus, about 1.417 million gallons per year
are available for replacement of consumptive use by the Project.
4.5 Water Balances
The water balances at the River (rates and cumulative volumes) were computed quarterly
using the estimated river diversions, lagged return flows, and Twin Lakes replacement
water. The results of the computations aze given on Table 3.
Quarterly periods in Table 3 are arranged to be synchronous with the water year (Nov 1-
Oct 31). Thus, the first quarter is May through July 1998, the second quarter is August
through October, and so forth through 20 quarters or five yeazs.
