distribution of the accretive/depletive effects of the sources of supply. at the end
of the first reporting period as provided for in An. m, App. A, Tab 3B.

Within six months from the date the Water Management Committee completes
the "Tracking/Accounting Procedure" described in Milestone Wl4-1, Colorado
will provide to the Governance Committee a calculation of the average monthly
distribution of the cumulative effect at the state line for anticipated water related
activities in the South Platte River Basin in Colorado for the period ending five
years from the effective date of the Cooperative Agreement (in accordance with
An. ill, App. A, Tab 3B).

Colorado will monitor population increase and net change, location and mix. of
water sources in the South Platte River Basin in Colorado and, within one year
of the effective date of the Cooperative Agreement, report such information to
the Governance Committee (in accordance with An. ill, App. A, Tab 3B).

Colorado will elect which option it will undertake for new water related
activities in the North Platte River Basin in Colorado as provided in An. ill,
App. A, Tab 3B.

Wyoming will develop means, if such are necessary, for protecting Program
water deliveries to the Wyoming-Nebraska state line.

Wyoming will develop means for protecting existing flow conditions in
Wyoming by: monitoring and annnally reporting new water related activities in
the North Platte River Basin in Wyoming within its boundaries; and, using the
procedures and methodologies developed pursuant to Milestone Wl4-1,
analyzing means of offsetting such depletions if a Program is implemented.

The Governance Committee (or the Water Management Committee if so
designated) will begin developing a "Tracking/Accounting Procedure for
Determining Depletion/Accretion Impacts for the Three Program Water Projects
and New Water Related Activities, Including Water Conservation/Supply
Projects. n This procedure will include:

/

determination of existing flow conditions in the associated habitats and at
the Colorado-Nebraska, Wyoming-Nebraska, and Colorado-Wyoming
state lines (hereinafter "the state lines n);

.I

determination of lag and gainlloss factors, and an associated verification
monitoring network, for use in determining how the distance of
depletions from and accretions to the river affect flow conditions in the
associated habitats and at the state lines;
