5.4 Use of water available under the subject water rights by
Boulder in its municipal water supply system consumes a portion of
the water so used. Boulder has demonstrated that the depletive
effect of the consumptive use in its municipal water supply system
during the April through October period of each year from base
(indoor) use and non-base use (lawn, park and. open space
irrigation, filling of swimming pools and other outdoor use) is as
follows:
Month Percent DepleteT
April 21%
May 39%
June 48%
July 53%
August 48%
September 34%
October 17%
The quantity of water available under the subject water rights that
has historically been or would in the future be consumed in
Boulder's municipal water supply system if the subject water rights
are used for their decreed municipal and related uses rather than
for instream flow use hereunder is water that has not returned and
would not in the future return to Boulder Creek and that would not
be available for use by other water users. Use of that quantity of
water for irrigation after the instream flow use of the subject
water rights has been completed can be made by lessees of Boulder
without causing injury to any vested water right or decreed
conditional water right.
5.5 Water available under the subject water rights described
in paragraphs 2.1 through 2.5, 2.7 and 2.8 which has been used for
instream flow purposes hereunder may be used by lessees of Boulder
downstream of the terminus of Segment C described in paragraph 4.1
above, subject to the following terms and conditions:
A. Use of water available pursuant to the terms and
conditions of this Part V shall be for irrigation purposes only
during the months of April through October of each year and such
irrigation use shall be made only by the owners of the ditches
described in paragraph 5.2 above pursuant to leases with Boulder.
B. On or before March 15 of each year, Boulder shall
furnish copies of leases to State water administration officials
and, upon request, to any of the parties hereto. These leases
shall include the names of the parties with whom such leases have
been entered into, the ditches into which available water is to be
