Join a former fly fishing guide on the beautiful East River near the Roaring Judy Fish Hatchery for a relaxed, beginner‑friendly fly fishing experience designed just for COSA attendees. Participants will head to a public access point to learn the basics of fly fishing, including fundamental casting techniques, reading the water, and understanding river etiquette. We will also casually discuss some of the everyday challenges of managing a popular public fishery, the primary focus of this session is to get outside, learn a new skill, and enjoy the river. No prior fishing experience is necessary, and experienced anglers are welcome as well. $10 fee

Join Westfeather guides for a hands-on exploration of the aquatic insects that drive river ecosystems that fuel some of the best fly fishing opportunities in Colorado. Participants will collect, identify, and sort aquatic insects from the Slate River into their respective families while learning about their life cycles and ecological importance. We will discuss how these insects fit into the broader riparian ecosystem and examine the relationships between water quality, habitat, and aquatic biodiversity. Participates will then compare the natural insects they find to artificial fly patterns used in fly fishing. Through demonstrations and discussion, participants will learn how anglers imitate different insect life stages and use specific techniques to match what fish are feeding on throughout the year. This field experience combines ecology, entomology, and fly fishing into an engaging outdoor learning opportunity.

This field trip is designed for wildlife viewers, non-hunters, and hunters to share our love of wildlife and build community as we focus on cultivating common ground. A hunter will lead a nature walk as we track elk in a nearby nature area and learn the fundamental naturalist skills needed for hunters and wildlife viewers alike! Discover how skills like reading signs and habitat clues benefit all wildlife enthusiasts, turning potential division into a shared future for wildlife and public lands.
