New Seasonal Fishing Closures on Blue River and Tenmile Creek: What Anglers Need to Know

Colorado anglers, take note! A new seasonal fishing closure has been implemented on parts of the Blue River and Tenmile Creek in Summit County. These closures are part of ongoing efforts by Colorado Parks and Wildlife (CPW) to protect vulnerable fish populations during critical periods. As conservationists and anglers alike, it’s important to understand not just when and where these closures are happening, but also why they’re crucial for the long-term health of our rivers and the species that call them home.

Why Are These Fishing Closures Happening?

Fishing closures are about allowing fish populations to thrive during their most sensitive times. In this case, the closure primarily focuses on periods when fish spawn or face environmental stressors, such as low water levels or elevated water temperatures.

• Spawning Protection: Fish are particularly vulnerable when they spawn. Disturbances during this period can lead to failed spawning efforts, putting entire populations at risk. By limiting fishing during these times, CPW is working to ensure fish populations, particularly trout, have the chance to reproduce and maintain healthy numbers in Colorado’s rivers.

• Environmental Stress: As temperatures rise and water levels drop during certain seasons, fish experience additional stress. Fishing in these conditions can exhaust fish more quickly, leading to higher mortality rates even with catch-and-release practices. Seasonal closures help reduce this strain, allowing fish populations to recover​

   

When and Where Do the Closures Apply?

According to CPW, the seasonal fishing closures will affect certain sections of the Blue River and Tenmile Creek during specific times of the year. These closures are aimed at the areas where fish are most likely to spawn and where water conditions are expected to be particularly challenging for the fish.

• Blue River: Closures affect the portion between Dillon Dam and the confluence with the Colorado River.
• Tenmile Creek: Sections between Frisco and the confluence with the Blue River will also be impacted.

These closures typically take place during the warmer months when water levels are lower and fish are spawning or facing temperature stress​

How Can Anglers Support These Conservation Efforts?

Supporting these closures isn’t just about following the rules—it’s about taking a proactive role in preserving Colorado’s aquatic ecosystems. As anglers, we play a vital role in sustaining the environments we enjoy. By respecting these closures, we help ensure that future generations of fish can thrive, and in turn, that fly fishing in Colorado remains world-class for years to come.

1. Respect the Closures

First and foremost, respect the designated closure dates and locations. These decisions aren’t made lightly, and they are based on research and data aimed at improving the overall health of the fish populations.

2. Practice Ethical Fishing

When fishing outside of closure periods, continue to practice catch-and-release and use barbless hooks to minimize harm to fish. The less stress we place on these populations, the healthier they will remain.

3. Support Habitat Restoration

Many rivers across Colorado, including the Blue River, are part of ongoing habitat restoration projects. These efforts aim to rebuild and protect the natural environments that fish need to thrive. Whether through donations, volunteer work, or simply spreading awareness, anglers can contribute to the restoration of vital waterways​

The Bigger Picture: Conservation and Sustainability

These closures remind us that our role as anglers extends beyond just catching fish—it’s about ensuring the sustainability of the waters and ecosystems we love. CPW is leading the charge, but each of us can contribute to conservation efforts in our own way. By following regulations, practicing responsible fishing, and supporting restoration projects, we help protect Colorado’s native fish species and ensure that fishing remains a treasured activity in the state.
