Water Ownership

Owning C-BT Project Water


By the time Colorado-Big Thompson (C-BT) Project water flowed through the Adams Tunnel in 1947, Northern Water staff had already spent a great deal of time determining how the project would operate. This included very detailed contracts, rules and regulations to allot 310,000 acre-foot units of C-BT Project water among thousands of agricultural, industrial and municipal water users in need of supplemental water from Colorado’s largest transmountain water diversion project.  

Northern Water offers a number of documents that impact C-BT allottees and water users. These documents include programs, policies, guidelines, rules and procedures. Not all programs or policies adopted by the Northern Water Board of Directors have corresponding rules and procedures. Rules, if applicable, describe a corresponding program or policy and how we implement that program or policy. Procedures, if applicable, typically describe operational details of a corresponding program or policy.
