Colorado's Drought Forces Drastic Measures: Antero Reservoir Drainage

Understanding the Drought Impact

Colorado is facing one of the driest years on record, leading to critical decisions by state water officials. Denver Water has announced the draining of Antero Reservoir—located in South Park, Park County—effective immediately. This unprecedented measure underlines the severity of drought conditions that have gripped the area.

Denver Water serves approximately 1.5 million customers, making this decision especially impactful for residents who depend on reliable water sources.

Why Antero Reservoir?

The draining of Antero Reservoir is not a decision taken lightly. Water will be transferred downstream to Cheesman Reservoir, a vital step aimed at minimizing evaporation losses during a year with historically low snowpack. Officials estimate this transfer could save around 5,000 acre-feet of water, roughly 25% of Antero's total capacity.

“Antero is a drought reservoir, designed to provide water to our customers during a severe drought. Consolidating this water into Cheesman will help us make the most of the water we have.” — Nathan Elder, Water Supply Manager at Denver Water

This strategic transfer is critical as typical replenishment from snowmelt is unlikely this year due to alarming reports of record-low snowpack across Denver Water's supply areas.

The Broader Implications of Drought

The decision to drain Antero Reservoir echoes the devastating trends in drought conditions impacting not just Colorado but the broader Colorado River Basin. This move is part of a larger drought response strategy, allowing Denver Water to rely more heavily on resources from the South Platte River Basin while relieving some pressure from Western Slope sources, which are also struggling with below-normal snowpack levels.

Significantly, historical patterns show that Antero Reservoir had been drained previously during the notable 2002 drought, and discussions regarding similar actions were held in 2013 but ultimately dismissed after late-season snowstorms improved conditions.

Environmental and Recreational Concerns

With the reservoir now closed for all recreational activities—including fishing, boating, and camping—there will be considerable disruptions for outdoor enthusiasts. Denver Water has committed to working with Colorado Parks and Wildlife to relocate fish populations before water levels drop drastically.

The reservoir is a cherished spot for anglers and outdoor lovers alike, especially during the warmer months. Although efforts will be made to facilitate a smooth transition for local wildlife, the reopening will largely depend on when water levels can be safely restored.

Looking Ahead: A Call for Adaptive Management

As we continue to navigate the ramifications of climate change, it's crucial to consider how water management strategies can evolve. The proactive measures being taken in Colorado highlight the need for innovative thinking around resource management. This moment underscores the interplay between policy changes, environmental challenges, and community needs.

Denver Water's decision to drain Antero Reservoir could serve as a case study for other regions grappling with similar circumstances. In an era where policy and natural phenomena increasingly intersect, clear reporting helps ensure trust in civic and business decisions affecting us all.
