Lower Arkansas Valley Water Conservation District board meeting recap

Pueblo dam releases

From The Bent County Democrat (Bette McFarren):

The water supply is greater than normal, with Turquoise at 121 percent of normal, Twin Lakes at 98 percent of normal and Pueblo Reservoir at 135 percent of normal. The Pueblo Reservoir must be down to a certain level by April 15, making a spill possible to avoid flooding. Farmers are taking water they can use as requested to ease the situation. Reservoirs in the area are full or nearly full.

Since the rainfall has been less than usual in winter 2017-2018, the abundant water supply is good news for area farmers. The snowpack in the Arkansas River Basin is 59 percent of normal and 54 percent of last year. The normal peak date is April 11 and these figures are as of March 19. All the water in the flood pool must be out by May 1, so that an upriver rainstorm will not cause flooding on the lower river. Therefore, the reservoir will start spilling excess water on April 15. A spill benefits whatever entity has the call on the river; for example, it could be the Rocky Ford Highline, or Holbrook or Fort Lyon by priority dates (original priority date).

The hydroelectric plant being constructed at Pueblo Reservoir is progressing as planned. The Lease of Power Privilege has been finalized with the South East Colorado Water Conservancy District. Reclamation has approved the design, specifications, and submittals for phase 1 and 2 and is currently reviewing the final phase. Construction on the plant began in September 2017. The anticipated start-up for the first turbine is early June 2018.

The hydro produced will be purchased by Fountain and Colorado Springs, said Chris Woodka of the SECWCD on Thursday. “The reason is that Black Hills declined to incorporate the power into its portfolio.” SECWCD has a carriage agreement with Black Hills when the plant starts producing. Woodka continued, “The annual average for production is around 28 million kWh per year, which is basically enough for 4,500 homes.” Revenue from the plant will benefit the Southeastern District, but a 30-year contract with Fountain and a 10-year contract with Springs accounts for all power generated.
