Extreme drought is hitting Colorado hard, but why are some of its largest towns not implementing mandatory watering restrictions? This article delves into the complex water management strategies of Front Range communities, exploring the reasons behind their varying approaches to conservation and the potential implications for the state's water supply.
The Drought's Impact
Colorado is facing an extreme drought, with nearly the entire state experiencing some level of aridity. The Front Range, a highly populated urban corridor, and the mountains that supply much of the state's water are particularly affected. Record-low snowpack has led to anemic streamflows, moisture-sucking soil, and drained reservoirs, with federal authorities describing the situation as severe, extreme, and exceptional.
Water Management Strategies
Despite the widespread drought, 13 of Colorado's 25 largest cities and towns, home to over 1.5 million people, have not imposed additional mandatory water use restrictions. These communities, including Fort Collins, Pueblo, and Boulder, have asked customers to voluntarily cut back water use, with varying degrees of success. Water providers set drought restrictions based on their water sources and reservoirs, and communities with diverse water portfolios and powerful water rights are better equipped to withstand the drought.
A Complex Web of Water Rights
John Thornhill, Windsor's director of community development, explains that each district and provider has unique water rights and storage rights, leading to significant differences in water management strategies. Kim Hutton, Boulder's water resources manager, notes that the lack of mandatory restrictions in some cities can be confusing to residents, especially when they see headlines about extreme drought and mandatory restrictions in other areas.
The Case of Englewood
Englewood, a town with senior water rights on the South Platte River, was initially without mandatory restrictions. However, even with these rights, the town is feeling the strain of the drought. The city council will soon decide whether to impose mandatory watering restrictions, limiting outdoor watering to two days a week, a significant change for a town that has never implemented such measures.
Voluntary Conservation Efforts
Voluntary conservation efforts have shown mixed results. Erie, for example, has achieved a 10% reduction in water use compared to the 5-year average through a voluntary two-day outdoor watering restriction. In contrast, water use in Fort Collins and Boulder is slightly above or at the 5-year average, while Colorado Springs' use is up about 7%. Denver Water and Aurora Water have seen significant drops in water use under mandatory restrictions, with Denver Water's use down 5% and Aurora Water's use down 9%.
Agricultural Use and Water Conservation
Water managers emphasize that municipal water use is dwarfed by agricultural use, which accounts for nearly 90% of the state's water consumption. While water use is up in some towns, per capita water use has decreased in others, such as Windsor, where it is 20% lower than in 2012. The drought's impact on agricultural use is significant, with farmers fallowing fields due to water scarcity.
Implications and Future Concerns
Water leaders warn that subsequent years of dryness will exacerbate the current situation. The first year of drought can often be managed, but the second and third years become increasingly dire. The lack of mandatory restrictions in some Front Range communities, despite the severe drought, raises questions about the state's water management strategies and the potential impact on Western Slope water conservation efforts.
In conclusion, the varying approaches to water management in Colorado's largest towns reflect the complex interplay of water rights, conservation efforts, and the state's diverse water sources. As the drought persists, the state must carefully consider its water policies to ensure a sustainable water supply for its residents and the environment.
