March 7, 2007 – Scope of Work Task Order 200 7 - 003
Technical Support for the Basin Roundtables – Needs Assessment
Work Plan Development and Project Management Assistance

Deliverable: Draft and final w ork plan for completing Task 2 including recommended
f unding mechanism.
3) Basin - wide – Identify vulnerabilities to water supply shortages for Gunnison Basin
municipalities.
SWSI Phases I and II identified several municipalities in the Gunnison Basin that may
not have the drinking water security and level of system redundancy that is
recommended to protect against unforeseen shortages. These shortages could be
drought related, infrastructure related and/or system related. Several significant
examples exist in Gunnison Basin, including but not limited to the To wns of Ridgway
(0.4 day treated water supply), Ouray (0.5 day treated water supply), Orchard City
(not known), Hotchkiss (not known), Paonia (not known). One of the larger
providers, the Project 7 system in Uncompahgre basin has only an estimated 30 day
t reated water supply. This drinking water treatment and distribution system is
particularly important and potentially vulnerable as it serves up to 8000 water taps,
including 38,000 water users in 3 counties and is reliant on the Gunnison Tunnel as its
pre dominant supply. If an extended outage occurs in this system, 38,000 people are at
risk. Furthermore, this analysis should be performed using historical demand
conditions related to minimum supply conditions as appropriate (e.g., during the
drought of 2002 – 2004).
The Consultant will work with the needs assessment committee to expand upon the
list above and to determine the level of detail needed to describe the vulnerabilities.
The information from SWSI 1 and 2 will be used as a starting point for this ta sk. After
finalizing the list of water users and districts the Consultant will contact the water
users and districts to gather this information related to this task. This task will b e
coordinated with Tasks 1 and 6 .
Deliverable: Draft and final technical memorandums describing the results of the
information from the smaller communities.
6) Sub - basin Specific: Upper Gunnison – Review, refine, and/or confirm the estimate
of future snowmaking demands in the Upper Gunnison Basin.
With the growth of Crested But te Mountain Resort, there is some concern that
previous estimates of snowmaking water demands may need refinement. It is
important that this analysis be performed using the most up - to - date records to
capture the wide variety of conditions, as appropriate ( e.g., during the drought of
2002 – 2004). The Consultant will meet with Crested Butte Mountain Resort to assess
their estimates for future snowmaking. The results of this meeting will be reflected in
the Technical Memorandum created for Task 1.
Deliverable : Incorporation of the results of this task into Draft and Final Technical
Memorandum s created for Tasks 1 and 2.
