Overview The Northern Integrated Supply Project will supply 15 Northern Front Range water partners with 40,000 acre-feet of new, reliable water supply. The project consists of: • Two reservoirs (Glade and Galeton) • A forebay reservoir • Three pump plants • Pipelines to deliver water for exchange with two irrigation companies and for delivery to participants • Improvements to an existing canal to divert water off the Poudre River near the canyon mouth NISP will store excess water currently leaving the state in years of abundance. Since 2009, more than 4 million acre-feet of water has left the state downstream to Nebraska over and above Colorado’s legal requirements under the South Platte Basin Compact. Through an exchange with two local ditch companies, a 1980 direct flow right on the Poudre River and a 1992 storage right on the South Platte River the project will provide 40,000 acre-feet of firm yield to participants annually. Current Status The U. S. Army Corps of Engineers is currently working to complete the Final Environmental Impact Statement for NISP. Following release of the Supplemental Draft EIS in June 2015 and subsequent public comment, the Corps has been addressing more than 500 comments and 4,000 pages of documentation as it works toward a FEIS. The Corps estimates completing the FEIS in 2017, with a Record of Decision scheduled for 2018. At that point, project design will be updated and construction could begin in 2021. The ROD will be the Army Corps’ final determination on whether the project can proceed, and if so, what mitigation and enhancement conditions will be placed on the NISP participants as Northern Water pursues building NISP. In the meantime, Northern Water staff have proposed a conceptual mitigation plan and begun discussions with state agencies on the Fish and Wildlife Mitigation Plan and 401 Water Quality Certification processes. A Better Poudre River The 15 NISP participants have offered a refined conveyance concept for keeping more year-round flows in the Poudre River. This proposal enhances the aquatic habitat while also addressing impacts identified in the environmental permitting process and during the public comment period. The modified conveyance will release at least 14,300 acre-feet of water per year from Glade Reservoir to the Poudre River, beginning near the canyon mouth and continuing 12 miles downstream to a point near the Fort Collins Mulberry Water Reclamation Facility. These releases will then be recaptured by NISP participants downstream of downtown Fort Collins. This refined conveyance will release a minimum flow of 25 cubic feet per second during the summer and 18 cfs during the winter. It will increase current base flows in 8 out of 12 months in average years and 10 out of 12 months in dry years while also improving water quality. The NISP mitigation and enhancement plan includes the construction of bypass channels at the four major agricultural diversion structures through Fort Collins, another guarantee that these minimum flows will make it through the city and downstream while allowing fish to move freely upstream or downstream.

NISP will store excess water currently leaving the state in years of abundance. Since 2009, more than 4 million acre-feet of water has left the state downstream to Nebraska over and above Colorado’s legal requirements under the South Platte Basin Compact. Through an exchange with two local ditch companies, a 1980 direct flow right on the Poudre River and a 1992 storage right on the South Platte River the project will provide 40,000 acre-feet of firm yield to participants annually.
Current Status
The U. S. Army Corps of Engineers is currently working to complete the Final Environmental Impact Statement for NISP. Following release of the Supplemental Draft EIS in June 2015 and subsequent public comment, the Corps has been addressing more than 500 comments and 4,000 pages of documentation as it works toward a FEIS.
The Corps estimates completing the FEIS in 2017, with a Record of Decision scheduled for 2018. At that point, project design will be updated and construction could begin in 2021.
The ROD will be the Army Corps’ final determination on whether the project can proceed, and if so, what mitigation and enhancement conditions will be placed on the NISP participants as Northern Water pursues building NISP. In the meantime, Northern Water staff have proposed a conceptual mitigation plan and begun discussions with state agencies on the Fish and Wildlife Mitigation Plan and 401 Water Quality Certification processes.
A Better Poudre River
The 15 NISP participants have offered a refined conveyance concept for keeping more year-round flows in the Poudre River. This proposal enhances the aquatic habitat while also addressing impacts identified in the environmental permitting process and during the public comment period. The modified conveyance will release at least 14,300 acre-feet of water per year from Glade Reservoir to the Poudre River, beginning near the canyon mouth and continuing 12 miles downstream to a point near the Fort Collins Mulberry Water Reclamation Facility. These releases will then be recaptured by NISP participants downstream of downtown Fort Collins.
This refined conveyance will release a minimum flow of 25 cubic feet per second during the summer and 18 cfs during the winter. It will increase current base flows in 8 out of 12
months in average years and 10 out of 12 months in dry years while also improving water quality.
The NISP mitigation and enhancement plan includes the construction of bypass channels at the four major agricultural diversion structures through Fort Collins, another guarantee that these minimum flows will make it through the city and downstream while allowing fish to move freely upstream or downstream. Currently the Poudre River can run dry at some locations as irrigators exercise existing water rights.

Glade Reservoir
Glade Reservoir will be located northwest of Fort Collins near the intersection of U.S. Highway 287 and State Highway 14. It will be 5 miles long, 260 feet deep and have the capacity to store 170,000 acre-feet of water, slightly larger than Horsetooth Reservoir. The water to fill Glade Reservoir will be diverted from the Poudre River during mostly high-flow times using the already existing Poudre Valley Canal near the canyon mouth. There will be no new structures on the river. The reservoir site is divided by U.S. Highway 287 that travels between Fort Collins and Wyoming. Therefore, about seven miles of the highway will be relocated to the east.
South Platte Water Conservation Project (Galeton Reservoir)Galeton Reservoir will be located east of Ault and northeast of Greeley. It will store about 45,600 acre-feet of water at full capacity. The water to fill Galeton will be diverted from the South Platte River downstream from Greeley at high-flow times. Galeton water is proposed to be delivered to two agricultural irrigation companies in exchange for a portion of the Poudre River water they currently use.
More than half of NISP’s planned diversion from the Poudre River includes water that has already been diverted for decades by these two ditch companies, and also employs the use of existing infrastructure wherever possible.
Colorado Water PlanThe November 2015 release of Colorado’s Water Plan reinforced the necessity of additional water storage projects to help meet Colorado’s future water gap. The plan identifies the need for 400,000 acre-feet of additional storage statewide. NISP can play a role in meeting the impending water gap in Colorado.
The gap is the difference between the estimated future water demands and the existing supplies to the year 2060. The plan also identifies water conservation and increased water transfers between the agricultural and municipal sectors as additional solutions to help meet the impending gap.
The NISP participants have reduced their per capita water usage by more than 20 percent in the past 15 years. /Gladereservoir
