Project Status

Northern Water and the 15 NISP participants have been going through the federal permitting processes for several years, with that hard work and persistence now paying dividends.

In the fall of 2017, the NISP Fish and Wildlife Mitigation and Enhancement Plan was approved by the Colorado Parks and Wildlife Commission and Colorado Water Conservation Board, with Gov. John Hickenlooper also putting his signature on that document.

Additionally, in the summer of 2018, officials from the Army Corps of Engineers released a Final Environmental Impact Statement outlining the impacts of the Northern Integrated Supply Project, as well as three alternative projects. It also looks at the effects to the environment if no action alternative is approved. In addition to marking yet another step in a 15-year federal permitting process, the FEIS showed that no new significant issues have popped up and that the impacts can and will be mitigated.

In January 2020, the Water Quality Control Division of the Colorado Department of Public Health and Environment issued NISP the Colorado 401 Water Quality Certification, which is part of the federal permitting process through Section 401 of the Clean Water Act.
