Update October 2022
The Supreme Court is currently hearing arguments in the Sackett v. EPA case — “dispute that had been expected to significantly narrow the scope of the Clean Water Act.” The result of this case remains to be seen, but it has the potential to gut the EPA’s ability to define, designate, and protect wetlands, among other ephemeral waters.
The importance of state action to protect Colorado waters regardless of what’s happening at the federal level has never been more fundamental. Scroll down to learn more about the Clean Water Act’s role in protecting the state’s most precious waters; the difficulties it has faced in the past several years; and what’s at risk in Colorado if the General Assembly doesn’t act to protect the upwards of 50% of Colorado streams, rivers, and wetlands that face loss of protection should the CWA be rolled back.

“All living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community.”
– Colorado River explorer John Wesley Powell describing watersheds as systems.
In April 2020, when the Trump-era Navigable Waters Protection (NWP) Rule went into effect in Colorado, leaving upwards of 25,000 miles of Colorado streams vulnerable to pollution and construction impacts, we saw just how fragile our relationship can be to the watershed community to which Colorado belongs. Ephemeral streams, which respond primarily to precipitation events and flow seasonally, constitute 68% of waters in Colorado, were put especially at-risk.
Up to 50% of all Colorado streams, rivers, and wetlands are at risk of being irrevocably harmed by rollbacks to the Clean Water Act. This could lead to numerous harmful outcomes. Regardless of their size or frequency of flow, streams and wetlands are connected to downstream waters and strongly influence their function. People, birds, and other wildlife gain many beneficial ecological services from freshwater ecosystems such as clean drinking water and wildfire resilience.
Although the Clean Water Act was re-instated later in 2021, our rivers, streams, and wetlands could continue to face threats — at both a federal and state level — until we have strong state action preventing pollution and protecting our waters. If we do not, we may see our iconic riverbanks and wetlands turned into parking lots, malls and housing developments, filled by dams or dried up by diversions. We could see our meandering backyard streams lost under piles of dirt. One thing is clear: Colorado waterways deserve protection. We need urgent and immediate state action to ensure our waterways and clean water are protected, regardless of who is in the White House. While a challenge from Colorado’s Attorney General Phil Weiser protected Colorado’s streams for an additional 10 months following the rule’s implementation nationally, it is now up to Colorado’s General Assembly to take the action necessary to protect the streams and wetlands that provide reliable drinking water, crucial wildlife habitat, and sustain a $19 billion water-based outdoor recreation economy in the state.
Make Your Voice Heard
In late 2021, the EPA announced their intention to revise the definition of “waters of the united states.” The public comment period ended in early-February, 2022.
The Clean Water Act remains in jeopardy as the Supreme Court hears arguments in late-2022. Check back on opportunities to engage to ensure Colorado’s state waters remain protected, regardless of what happens at a federal level.
Maps of Threatened Areas
These maps, created by Coalition partners Trout Unlimited and The Nature Conservancy, illustrate the extent of potential damage to Colorado’s streams and wetlands. In each, the darker the color, the higher the percentage of streams or wetlands lost in each watershed.
What We Could Lose
Rivers, streams, and wetlands across the state have the potential of being polluted by the Clean Water Act rollback, including places that many Coloradans know and love. From high altitude streams and wetlands to floodplains and dry desert washes, many of these critical areas are at risk. While Colorado’s beloved mainstem large rivers are not at risk, many of the smaller streams, washes, wetlands, and fens that comprise their upper watershed are. And these waters – and whatever else might be in them – travel downstream into mainstem rivers.
Areas under threat include:
The Quiet Cost
While iconic places across our state could lose protection as a result of these rollbacks to the Clean Water Act, some of the most tragic damage may be to our smaller, intimate backyard streams, wetlands, and marshes where protection is quietly disappearing.
At first, the damage might seem small and could go unnoticed. But small changes can lead to big impacts – particularly downstream. Paddlers enjoying small streams could come across stray piles of dirt blocking their way; hikers rounding a corner may find the sound of a babbling brook dampened; anglers might realize their favorite river bank is no longer conducive to casting a line. The damage may be done before it is discovered, and the cherished places that compel us to get outside — to love Colorado in all its natural splendor — could be lost quickly, quietly, and without consequence.
