RE: Justin Young Jr. Substitute Water Supply Plan
Sections 29 & 30, T22S, R44W, 6th P.M.
Water Division 2, Water District 67

Dear Mr. Healy:

We have reviewed your March 30, 1998 request for a substitute water supply plan on
behalf of Justin Young Jr. to allow construction and operation of a number of wildlife ponds and
"terraces". The structures will consist of one 13.5 acre-feet (9 surface acres) terrace in section
30, and two terraces totaling 3.2 acre-feet (2.31 surface acres) and one pond of 4.13 acre-feet
(1.64 surface acres) in section 29. The source of water will be surface flows originating as taii
waters from irrigation under the Amity Canal, and the structures will be constructed so as to be
drainable. While the pond will contain water year round the terraces will only contain water
during the months September through February.

Stream depletions will be caused by filling of all structures in September, and by
subsequent surface evaporation. Your estimates of monthly depletions, detailed on Attachment
A, also include amounts for saturation of tile soil underlying the pond and terraces to a depth of
3 feet. This year's initial operations are estimated to create an annual depletion of about 62
acre-feet. With the pond not having to be filled, subsequent year's depletions are anticipated to
be about 55 acre-feet. It is noted that contrary to the note on the proposed accounting form, ice
cover of a pond will not reduce the cllargeable evaporation.

At the end of February tile 3 terraces will be drained. Your submittal stated LAWMA
would want credit for this drainage, including "release" of water stored in the soil which is
greater than the available water holding capacity. Prior to receiving any credits for soil moisture
drainage, additional explanation and documentation of how such storage and drainage is
determined and measured must be provided.

Replacement of stream depletions is proposed by use of 74 acre-feet of consumable
water Mr. Young has purchased from Coiorado Springs Utilities (CSU) via the Lower Arkansas
Water Management Association (LAWMA). The 74 acre-feet will cover filling, evaporation, an
estimated 20% transit and storage losses, and according to an April 17, 1998 agreement
between CSU and LAWMA will be delivered into John Martin Reservoir's Kansas Offset account
in June. LAWMA has agreed to provide accounting services for this plan.
