Central Weld County Water District -Proposed Dry Creek Reservoir
Introduction
The Central Weld County Water District (CWCWD) is applying fora $3,937,500 loan to construct a
new water storage reservoir in a 50/50 partnership with the Little Thompson Water District (LTWD).
Both districts would jointly build, own and operate the proposed reservoir. The estimated total cost
of the project is $10,500,000. In conjunction with this loan request, the LTWD is also submitting a
$3,937,500 loan request. Please see the attached project summary and map.
Background
CWCWD and LTWD jointly own the Carter Lake Filter Plant that treats Colorado-Big Thompson (C-
BT) water for use by their customers. Currently, the filter plant has no raw water storage facility. All
water treated by the plant is delivered directly from Carter Lake to the filter plant through the St.
Vrain Supply Canal. Consequently, the Districts are entirely dependent on availability of water from
Carter Lake. In wet years, the Districts are unable to treat and store all of the water to which they
are entitled, and consequently must take less than their water rights would allow. Over the last 10
years, the Districts together have had to carry over or lose approximately 1000 acre-feet per year.
In dry years, the Districts can have a shortage of water that cannot be overcome by supply from
Carter Lake, and consequently are forced to meet their current demands by augmenting with water
from outside entities. In addition, any condition that would interrupt supply from Carter Lake such
as maintenance to Carter Lake or the St. Vrain Supply Canal also would cause interruption in
operation of the treatment plant. Currently, the only storage the Districts have, other than Carter
