Dear Mr. Walcher:

By transmittal of this letter, the Department of the Interioris hereby requesting that the
State of Colorado institute the administrative process necessary for the Colorado Water
Conservation Board (CWCB) to file an application for an instream flow appropriation .
with the Colorado Water Court, The proposed instream flow will be for the stretch of the
Gunnison River below the Gunnison Diversion Dam through the Black Canyon, to the
confluence of the North Fork of the Gunnison River. The primary beneficiary of this
proposed instream flow appropriation is the Black Canyon of the Gunnison National Park
(P~k).

The Agreement signed last month among yourself, Attomey General S,alazar, and the
, Department of the Interior, was the first step in.a historic partnership designed to
demonstrate that the water neeqs of the United States, in rnany circumstances, can be rnet
by working colIaboratively with the states in a manner that protects existing water users.
Under the terms of the Agreement, the United States will obtain a Federal reserved right
of300 cubic feet per second (cfs) or natural flow, whiche-voris less, for the Park under
the current proceedings in Colorado Water Court for quantification of the reServed right
for the Park. The Agreement also specified that Colorado, through the CWCB, will
obtain an instream flow right with a 2003 priority date to be held by the State for the
benefit of the Park. This right shall only be exercised if Blue Mesa Reservoir is projected
to fill and spill by July 31 in any given year, If Blue Mesa is projected to fill and spill by
July 31, then any water beyond that which satisfies present and future obligations (lfthe
Aspinall Unit shall be held by CWCB for an itlstream flow right. When the CWCB
instream flow right is in priority, the right shall not be exercised in a rnanner that
interferes with Aspinall Unit operations.

We understand that in certain years where there are significant flows in the Gunnison
Basin, the amount of water available for the instream flow appropriation could be
significant. In light of the standards of Colorado law (i.e. that the appropriation shall
only be for the minirnum amount of water nepessaryto protect the environment to a
reasonable degree), we are only requesting aJ,'l appropriation for the spring runoff period
