Projected demands in Table 3 -2 were calculated using 220 gpcd estimate from SWSI and the population
projections available from county data.
3.1.3.2 La Plata County
La Plata County did not have water resource planning studies available, but water demand estimates were
made using population data from the County's 2030 Transportation Integrated Plan (2030 TRIP). These data
were, in turn, taken from the State of Colorado Demography section and are summarized in Table 3 -3.

projections available from the county data.
3.2 Water Providers with Potential Interest in A -LP Project
Water
The SWSI water needs assessment identifies areas and water providers in La Plata and Archuleta Counties
with future demands for additional water supply. It is important to note that many of these areas and water
providers identified in the SWSI needs assessment: (a) have demands less than 300 AF /YR, (b) are located in
unincorporated portions of the county, and /or (c) are located relatively far from the A -LP Project. Because
of these factors, Brown and Caldwell has focused in this initial demand study on the larger water providers in
Archuleta and La Plata Counties that are within proximity to Lake Nighthorse.
In addition to reviewing this SWSI needs assessment list, Brown and Caldwell was provided with letters of
interest to purchase A -LP Project water from the State. This included letters from the La Plata West Water
District and La Plata - Archuleta Water Authority.
From this information and data, Brown and Caldwell, the following water providers became the focus of the
demand investigation:
• City of Durango, Colorado
• La Plata Archuleta Water District
• La Plata West Water Authority
• Lake Durango Water Authority
• Pagosa Area Water and Sanitation District and San Juan Water Conservancy District
• Town of Bayfield, Colorado
