Due to the low levels of water, the federal government has declared a Tier 1 water shortage in the Colorado River for the first time ever. This declaration reduces the amount of water that Arizona, Nevada and Mexico can claim from the river.
“The Tier 1 shortage declaration highlights the challenges facing the Colorado River Basin; however, this did not come as a surprise,” says Taylor Hawes, The Nature Conservancy’s Colorado River Program Director. “The Colorado River has witnessed a steady decline in flows since 2000 that impacts communities, agriculture, industry, and the health of our rivers in the region. Even as flows decreased, our demand reductions have not kept pace.”
The declaration not only reduces the amount of water available for cities, but it will likely restrict water supplies for farmers. Some farmers may be forced to sell cattle, switch to different crops, or use groundwater from wells.
Colorado River Hit Hard by Climate Change
The Colorado River provides drinking water for more than 40 million people, hydroelectric power to meet the needs of over 7 million people, and water for 30 Native American Tribes. It irrigates around 5 million acres of fields that supply vegetables to the entire world and supports a thriving $26-billion recreation and tourism economy, as well as a wide variety of wildlife.
But climate change is hitting the Colorado River hard. The West has been in the grip of a drought for over 20 years that scientists believe is the worst in a thousand years, and the river is starting to feel the pinch. Its flows are powered by snowmelt in the Rocky Mountains, and as precipitation declines across the region, the river’s supply has dwindled too. Higher year-round temperatures also mean that the water evaporates faster while water use increases. These challenges make it harder and harder to balance the needs of people and the fish and wildlife that depend on healthy, flowing rivers.
“The Colorado River can be a model for resiliency and sustainability but not without a concerted and significant effort by stakeholders in the region,” Says Hawes. “While stakeholders have been developing solutions and adapting to a drier future, we must all accelerate the pace. We need short term solutions to stabilize the system while also working on longer term solutions. These include reducing water use across sectors, modernizing infrastructure, improving forest health, enhancing natural infrastructure, using technology to bolster groundwater levels, and improving stream and river health."
Leading on Innovative and Collaborative Solutions
Already, water levels in Lake Powell and Lake Mead, the two major reservoirs that store the Colorado River’s water, are down to 34% of their capacity and may soon drop too low to spin the hydroelectric turbines in their dams. Some smaller reservoirs began emergency releases in summer 2021 to prop up water levels in these lakes.
The situation is serious, but there’s plenty we can do to improve it. We know that the West will continue to get hotter and drier due to climate change. By proactively working together and planning for this future, we can share the Colorado River’s water equitably among all those who need it, including nature. We can use water more efficiently in our homes and businesses, improve agricultural irrigation infrastructure, adopt innovative water sharing approaches, and plant crops that use less water. With proper planning, the river will have enough water for fish and animals as well as people.
“Water issues are complex and require partnership and collaboration,” says Hawes. “The Nature Conservancy has worked in the Colorado River Basin for 20 years and appreciates the critical importance of partnerships in charting a sustainable and resilient future. However, the river system has changed more quickly than we have adapted. We must accelerate our efforts and think more broadly and creatively than ever before to chart a sustainable course. We must work together, testing ideas, sharing knowledge and investing in both short-term and long-term solutions in order to have the greatest impact in a short amount of time. This approach is our best path forward to minimize more future shortages on the river.”
With our contacts in the region and our history of bringing diverse stakeholders together, TNC is ideally situated to broker agreements that keep the Colorado River healthy. In Colorado, we developed the Yampa River Fund, a compact in which downstream users pay to protect the health of their water supply near its source. In Arizona, we developed a groundwater recharge system and helped farmers switch to water-efficient crops. We helped Mexicali, Mexico, invest in wastewater treatment solutions to leave more water available for nature. We are supporting policies at local, regional, and national levels that safeguard water supplies in the arid West.
The Nature Conservancy is a global conservation organization dedicated to conserving the lands and waters on which all life depends. Guided by science, we create innovative, on-the-ground solutions to our world’s toughest challenges so that nature and people can thrive together. We are tackling climate change, conserving lands, waters and oceans at an unprecedented scale, providing food and water sustainably and helping make cities more sustainable. The Nature Conservancy is working to make a lasting difference around the world in 81 countries and territories (40 by direct conservation impact and 41 through partners) through a collaborative approach that engages local communities, governments, the private sector, and other partners.
