Final Draft - Preferred Storage Options Plan
Southeastern Colorado Water Conservancy District
June 8, 2000

3. Winter Water stored in excess of70,000 af;

4. Non-Project water stored under contracts with municipal entities within
the boundaries of the District (limited to 163,100 at);

5. Winter Water less than 70,000 af;

6. Project water accumulated from the Arkansas River and its tributaries
under the District's East Slope water rights.

Under Re-operation Scenario B, the spill priorities listed above would not be
changed and entities would be allowed to store non-Project water in Project
storage space. Re-operation space would be under the fourth spill priority above.

Allocation Princioles

The District's Allocation Principles (November 29, 1979) provide for distribution
of Project yield and storage among participating entities, as follows:

Allocation ." ..lil Storage
TleIO'"
(%) (aflyr) (at)
FVA 25% 20,100 78,000
Arkansas Valley-East of Pueblo 12% 9,640 37,400
Arkansas Valley-West of Pueblo 4% 3,216 12,400
Pueblo 10% 8,040 31,200
Subtotal (Municipal) 51% 41,004 159,000
Irrigated Agriculture 49% 39,396 -
Unallocated Storage - -- 146,401
Total 100% 80,400 305,401

{1}

Yield is based on lon9-term average expected yield of 80,400 at. Yields are not guaranteed.
Annual allocation would be based on that year's yield times the allocation percentage.

Re-operation Scenario B was structured to maintain the yield of the Project
(80,200 af for the 1966-96 hydrology), while providing non-Project water storage
for municipal entities. Future demands on Project water were assumed to be 51
percent municipal and 49 percent agricultural, consistent with the Allocation
Principles.
