The Bureau of Reclamation is about to start moving water around the Upper Colorado River Basin. Here is what it could mean for fish.

The Colorado River Basin is home to fish that are found nowhere else on Earth and evolved 3 to 5 million years ago — well before dams, pipelines, and climate change reshaped the Colorado River. Their survival depends on careful planning to maintain healthy river flows.

Creating a Sustainable Future for the Colorado River

This is a critical moment for the Colorado River. Lake Powell and Lake Mead — the two major reservoirs on a river that provides water to 35 million people — have fallen to historically low levels. The U.S. Bureau of Reclamation is working to develop new guidelines for managing the river in the years ahead. This is our chance to build a more sustainable future for the Colorado River and the communities, fish, and wildlife that depend on it.

The Colorado River is Not Going to Wait for Politics

The states that share the Colorado River have failed to agree on how to protect it, leaving 35 million people without a clear path forward. We still have a chance to protect the river – but we must act now. Our communities need a plan that responds to climate change, proactively prepares for water shortages, promotes conservation across the Basin, and protects river health.
