On February 28th, 2024, Colorado state legislators issued a joint resolution expressing support for ongoing efforts to restore the clarity of Grand Lake. This marks a significant step forward for a project with a long history and potentially far-reaching implications for water management in the state.
Grand Lake, Colorado's largest and deepest natural lake, was once known for its pristine waters. However, the Colorado-Big Thompson Project (C-BT) operation has resulted in reduced clarity.
The C-BT, a federal project operated by Northern Water, moves water from the Western Slope of the Rocky Mountains to the Front Range for municipal and agricultural use.
During this process, sediment and algae from Shadow Mountain Reservoir are introduced into Grand Lake, leading to cloudy water, algae blooms, and excessive weed growth – all detrimental to the lake's health and recreational appeal.
Efforts to find a permanent solution to the clarity problem have been ongoing for years. Potential fixes include significant infrastructure changes to the C-BT or adjustments to operational strategies.
However, bureaucratic challenges have hindered progress. A technical working group is now considering novel approaches, such as addressing algae growth and introducing aeration within Shadow Mountain Reservoir.
While a resolution is desired, direct funding has not been identified. The Grand Lake clarity issue highlights the complex relationships between water infrastructure, water quality, and ecosystem health.
Though there's still much work to be done, the resolution provides renewed momentum for stakeholders involved in restoring Grand Lake. It signals a shared commitment to finding a solution that benefits all those reliant upon the waters of the Colorado-Big Thompson Project.
