Northern Water Board Approves Changes to Tracking Rule Procedures
The Northern Water Board of Directors has unanimously approved a change to Colorado-Big Thompson Project accounting procedures concerning C-BT water tracking.
During a rule-making hearing at the June 11 Board meeting, Directors heard about the changes to the rules surrounding the tracking of water from the Project. The new accounting procedures will require accounting of tracking data to be provided in a manner to allow for the administration of C-BT Project water return flows, which will help Northern Water protect them as described in the District’s Repayment Contract with the Bureau of Reclamation, the Water Conservancy Act and contracts with allottees.
The modifications affect only domestic and municipal users, and Northern Water staff met or contacted 26 municipalities, water districts and treatment plants in the months before the rule change was approved.
