Aurora Water proposes Wild Horse Reservoir to enhance water storage capacity

The Colorado Parks and Wildlife Commission has highlighted a significant development regarding the proposed Wild Horse Reservoir, which is expected to impact park management and operations in the region. During the second day of their meeting on April 26, 2025, officials discussed Aurora Water's plans to construct the reservoir as part of their strategy to enhance water storage capacity for users. The project is currently in the planning stages, with completion anticipated in the 2030s.

The proposed Wild Horse Reservoir will have a capacity greater than the existing Spinning Mountain Reservoir, featuring a depth of 100 feet and approximately 12 miles of shoreline. This development is seen as a collaborative effort, as Aurora Water is already a partner with Colorado Parks and Wildlife on the Spinning Reservoir project, fostering open communication between the two entities.

Commissioners raised important questions regarding the water rights associated with the new reservoir, particularly concerning the source of water that will fill it. The discussions revealed that water from the Arkansas River, currently transported via the Otero pipeline to Spinning Reservoir, may be redirected to the new reservoir. This potential shift raises concerns about the implications for Spinning Reservoir's water levels, especially during low seasons.

As the planning progresses, Colorado Parks and Wildlife is actively engaging with water resource experts to assess the potential impacts of the Wild Horse Reservoir on existing water systems. The commission emphasized the importance of thorough water modeling to understand how changes in water diversion could affect local ecosystems and water availability.

The meeting underscored the need for ongoing dialogue among stakeholders to ensure that the development of the Wild Horse Reservoir aligns with environmental sustainability and community needs. As the project moves forward, the commission will continue to monitor its implications for park management and regional water resources.
