WATER Located over the Dolores River is the grand McPhee Reservoir. Taking a massive space of around 4,470 surface acres, this is indeed one of Colorado’s largest lakes. The dam is 1,300 feet in length and 30 feet wide. As far as its crest goes, it stands 270 feet above the stream bed.

The creation of this reservoir was a result of the construction of Great Cut Dike and McPhee Dam in a saddle. Plenty of boating options are here, stop by Doc’s Marina for rentals. If you’re really keen to show your family how grand a dam can be, this one certainly deserves attention. It’s located in Dolores in Southwest Colorado near Cortez.

McPhee Reservoir can hold up to 381,000 acre-feet when full at 6,924 ft in elevation.

The capacity of the reservoir is divided up into three parts:

▪ Dead Pool – 100 acre-feet

▪ Inactive Capacity – 152,000 acre-feet

▪ Active Capacity – 229,000 acre-feet


Cortez is blessed with the high-quality Dolores River water out of McPhee Reservoir with which to begin the water treatment process. All water processed by the treatment plant is from McPhee Reservoir.  The water distribution system is planned and sized to provide for home and business uses, as well as fire protection. The minimum size distribution line installed in residential areas is a 6” line. Commercial area and feeder lines are usually 8” or 12” diameter lines.

ELECTRIC – Empire Electric

EEA purchases power from Tri-State Generation and Transmission Association. Tri-State supplies EEA with a 230,000 volt transmission line that comes from the Nucla/Montrose area. Tri-State’s transmission system passes through EEA’s service area to La Plata Electric Association’s service area to the east of EEA and that provides another layer of reliability.  To further enhance reliability on the western side of our territory, EEA began constructing a transmission interconnection in the Monticello Utah area in 2022 and it will be in service by late spring 2023. 

EEA buys our power from Tri-State, so for the most part, the Tri-State renewable generation mix is also EEA’s. Tri-State had a minimum of 20% renewable generation in 2021 as required by Colorado law and their Responsible Energy Plan will have them at 50% by 2024.
