Project Answers Participants' Need for Water Supplies

The Chimney Hollow Reservoir Project will benefit nine cities, two water districts and a power provider. Northern Water's Municipal Subdistrict is coordinating the permitting process for these residential providers, who face a serious lack of water supply as the region continues to grow.

Participants and Requested Storage

  • Broomfield (26,464 acre-feet)
  • Platte River Power Authority (16,000 acre-feet )
  • Loveland (9,587 acre-feet )
  • Greeley (9,189 acre-feet )
  • Longmont (8,000 acre-feet )
  • Erie (6,000 acre-feet )
  • Little Thompson Water District (4,850 acre-feet )
  • Superior (4,726 acre-feet )
  • Louisville (2,835 acre-feet )
  • Fort Lupton (1,103 acre-feet )
  • Lafayette (900 acre-feet )
  • Central Weld County Water District (346 acre-feet )

By 2050, these water providers' combined population will have far more than doubled what it was in 2005, to about 825,000 people. Water demand projections show a shortage in supply of 64,000 acre-feet in 2030 and 110,000 acre-feet by 2050.

To address this shortage, participants are relying on multiple approaches: conservation, reuse and additional supplies - including building Chimney Hollow Reservoir.
