Northern Integrated Supply Project

Northern Integrated Supply Project 

Two New Reservoirs to Support Northern Colorado's Growing Communities

The Northern Integrated Supply Project (NISP) will deliver 40,000 acre-feet of new, reliable water annually to 15 water providers across the Northern Front Range. These providers will serve nearly 500,000 residents by 2050, helping secure the region’s water future. 

Northern Water is leading the permitting, design, and construction of this vital project on behalf of its participants. Key components of NISP include: 

• Glade Reservoir and Forebay (northwest of Fort Collins) and Galeton Reservoir (northeast of Greeley)
• Relocation of U.S. Highway 287
• A new tunnel and canal to deliver water to the Glade Forebay from the Poudre River near the canyon mouth
• Five pump plants to support water movement and delivery
• Pipelines for water exchange with two irrigation companies and delivery to participating communities

Together, these elements form a modern, efficient water supply system designed to meet the needs of a growing population while supporting agriculture, recreation and environmental stewardship.
