First, the 3.59 percent NPANI water allocation is calculated. This is done because NPANI water cannot be allocated for irrigation. NPANI water is the Project water percentage that had once been allocated to irrigate lands that have since had the water sold off the land and removed from the ditch or canal system for Municipal use.
NPANI water is currently distributed as shown below
NPANIW Distribution (Percentage of Total Allocation) |
Percent |
Fountain Valley Authority |
0.45% |
Arkansas Valley Cities, Towns, and Entities lying East of Pueblo |
0.73% |
Arkansas Valley Cities, Towns, and Entities lying West of Pueblo |
0.27% |
Colorado Springs Replacement |
1.45% |
City of Manitou Springs |
0.35% |
Pueblo West Metropolitan District |
0.34% |
If the 3.59 percent of the amount of water available for allocation exceeds the NPANI water requests this water is then moved to the Municipal allocation.
The Municipal allocation of 51 percent plus any non-allocated NPANI water is calculated as follows:
- 25% to the Fountain Valley Authority members
- 12% to municipal entities east of the City of Pueblo
- 10% to the City of Pueblo
- 4% to municipal entities west of Pueblo
- Excess NPANI water pro-rata to the above areas
If the percentage allocated to a specific area exceeds the requests for Project water in that area the excess is then allocated to the other allocation areas pro-rata based on their percentages.
If within any single allocation area, any entity’s request is less than their individual allocation percentage the excess is then allocated pro-rata to the other entities within that area.
If all municipal requests for Project water are met, any excess water is then available to agriculture for the irrigation allocation.
Next, Project water for agriculture irrigation is allocated. This allocation is made only after the municipal requests are met up to 51 percent and the NPANI water requests are met, up the 3.59 percent of the annual Project yield. To be as equitable as possible, allocation of irrigation Project water is done proportionately on a portion of an acre-foot per acre eligible to receive Project water as determined by Reclamation Reform Act (RRA) reporting. Initially the District calculates the amount of Project water available per eligible acre by dividing the total amount of Project water available by the total eligible acres. This number is then used to calculate the allocation to each ditch. As with the municipal entities, if any irrigation entity’s request is met the excess allocation is then recalculated for the entities whose requests were not met. This may take several iterations to allocate all of the irrigation Project water.
The Project Water Allocation Policy requires, unless waived by the Board, 80 percent of Project water allocated to each entity for irrigation be used by November 15 of the year allocated and the remaining 20 percent must be used by May 1 of the following year.
