We have reviewed your submittals requesting renewal of the substit r suppl
plan for the above referenced gravel pit (well permit no. 48758-F). The required $21s
been paid, This approval will cover the period April 1, 2002 through July 31, 2004.
Out of the 4.3 acres of maximum groundwater exposure that will occur during this plan, 2
acres were exposed prior to January 1, 1981. The maximum estimated depletions to be
covered total 9.285 acre-feet annually, consisting of 9.225 acre-feet of net evaporation off of 2.3
acres of post-1980 ground water exposure, and 0.06 acre-feet of water lost with 2,000 tons of
mined product (4% loss by product weight). A monthly breakdown of these amounts and their
lagged affects on the Arkansas River is given on the attached table. No pumping occurs for
gravel washing, dust suppression, or concrete hatching purposes.
The source of replacement water to cover the plan's depletions is again from Lower
Arkansas Water Management Association (LAWMA). Pursuant to a February 27, 2002
agreement, LAW MA will provide up to 11 acre-feet of replacement water from its accounts in
John Martin Reservoir, and in return Bent County Ready Mix will assign to LAW MA the use of
12 shares of Fort Bent Ditch Company stock.
Bent County Ready Mix is willing to commit its 12 shares of Fort Bent Ditch stock to the
pit as a source of long-term renewable supply of replacement water. These shares are
estimated to yield 6.0 acre-feet per year (0.50 of/share delivered) in a dry year. IAWMA has
approved the use of the 5 LAWMA shares owned by Bent County Ready-Mix, which will be
used along with the 12 shares of Fort Bent Ditch Company to provide replacements. LAWMA
agrees to provide replacement water in an amount up to 11 acre-feet per year for replacement
of stream depletions caused by operation of the gravel pit.
The state and division engineers have reviewed the plan and the adequacy of each
source of water provided for use as augmentation water, including, where necessary, the
historical consumptive use of each water right, and return flows from diversion of waters
