Dear Mr, Healy:

We have reviewed your request for renewal of the Prowers County Gravel Pit substitute
water supply plan for the plan year April 1, 1998 through March 31, 1999. The required fee of
$217 has been paid.

It is anticipated that at the end of mining operations the maximum exposed ground water
surface of the gravel pit will be 3 acres, The anticipated maximum annual depletion to the
Arkansas River will be 13.58 acre-feet per year. consisting of 12.1 acre-feet of net evaporation
from 3 acres of ground water exposure, 0.48 acre-foot of water lost in product, and 1.0 acre-foot of
water used for dust suppression. Below is a monthly breakdown of this consumption with lagged
depletions to the Arkansas River.

This year's source of replacement water is to be administered by LAWMA. LAWMA has
contacted with Colorado Springs for 1,677 acre-feet of reusable water for the plan year, 17 acre-
feet of which will be dedicated to this plan to cover stream depletions and transit and storage
charges. Mr. Jim Rogers, from whom the County is leasing the pit, is paying LAWMA for the
