Clean, Drain, Dry

Clean, Drain, Dry: Tools and Resources for Colorado Anglers

If you fish in Colorado, you’ve probably heard “Clean, Drain, Dry.” It’s simple. It works. And it’s one of the easiest ways anglers can help prevent aquatic invasive species (AIS), including invasive mussels, from spreading into new waters.

Colorado Trout Unlimited has been coordinating with Colorado Parks and Wildlife (CPW) on AIS education and outreach. CPW has a strong set of angler-focused materials that are designed to be shared through fly shops, chapter meetings, events, and local outreach.

This post lays out what’s available, where to find Clean, Drain, Dry gear you can purchase, and where to find CPW resources for outreach and gear cleaning awareness.

Why Clean, Drain, Dry matters

AIS can spread when we unknowingly move plant material, mud, and standing water from one place to another, especially through boots, waders, nets, boats, and other equipment that comes into contact with rivers, lakes, and reservoirs. The best defense is prevention, and anglers play a huge role in that.

Clean, Drain, Dry doesn’t take long. But it can save a lot of trouble down the road.

CPW outreach materials available for anglers

CPW has several outreach resources that are ideal for fly shops, chapters, and community events:

  • Angler-targeted rack cards that walk through Clean, Drain, Dry in a clear, practical way

  • A wide variety of stickers, including many sourced from the Invasive Species Action Network (ISAN) out of Montana, plus some sticker designs CPW created in-house

  • Outreach signage posted at access points in areas of known risk or concern, including new needs along the Colorado River corridor as conditions evolve

If your chapter or shop wants educational materials to share locally, these are great tools.

CPW also has a publicly available ANS media package with outreach language and reference material specifically aimed at gear cleaning and awareness. This page is packed with information and is designed to be shared widely:

Fly shops: Clean, Drain, Dry pledge poster

CPW also has a pledge poster designed with fly shops in mind.

The idea is simple:

  • anglers sign a Clean, Drain, Dry pledge

  • if they sign, they can receive a custom sticker featuring Colorado river basins

  • it’s a quick, low-effort way to encourage better habits and keep Clean, Drain, Dry visible in the shop

Want boot brushes or towels? Here are the best places to buy them

A lot of anglers ask about Clean, Drain, Dry gear, things like boot brushes and towels that can live in your rig, boat, or gear bag.

CPW isn’t able to sell CPW-branded merchandise directly, but they recommend these nonprofit organizations where you can buy similar Clean, Drain, Dry gear and support invasive species prevention work in the process:

Wildlife Forever (towels, boot brushes, and other prevention tools):

NAISMA (North American Invasive Species Management Association) (handheld boot/shoe brushes, including hoof-pick style brushes identical to some CPW distributes):

ISAN (Invasive Species Action Network) (merch + stickers, we source many of our AIS stickers from them, and their products use the same branding as the stickers):

Request materials for your chapter, shop, or event

If you’re part of a Colorado TU chapter, a fly shop, or a local fishing group and want Clean, Drain, Dry outreach materials, the best place to start is CPW’s public ANS outreach package and gear cleaning resources here:

Thanks for helping protect Colorado waters, and for doing your part to keep Clean, Drain, Dry normal and expected everywhere we fish.

Tie-4-The Future: One Fly at a Time

Fly Tying at a STREAM Girls Program.

It’s time to dust off your vise, grab some materials, and tie flies for a cause that truly matters.

Colorado Trout Unlimited is excited to invite our members and chapters to participate in the Tie-4-The Future Challenge, a statewide effort to support TU’s education programs by doing what we love, tying flies. Every fly tied and donated helps connect youth to rivers, science, and conservation through hands-on learning experiences like Conservation and Fly Fishing Camp, STREAM Programs, and more.

What Is Tie-4-The Future?

Comparing a Tied Fly with a ‘Real Bug’ at Camp.

Tie-4-The Future is a friendly, chapter-based challenge that encourages TU members to tie flies that will be used in Colorado TU education programs. It’s simple, meaningful, and a great excuse to gather around a vise with friends—whether at home, at a brewery, virtually, or during a chapter meeting.

How it works is easy:

  • Tie as many flies as you’d like (click here to see recommended fly patterns)

  • Chapters collect flies from their members

  • Mail all flies together by April 1, 2026

  • Be sure to include your chapter name and number of flies

At the end of the challenge, the Colorado TU Chapter that ties the most flies will take home the Tie-4-The Future Trophy for a full year—along with some well-earned bragging rights 🏆.
The winner will be announced at the Colorado TU Spring Rendezvous in April.

Chapters: This Is Your Moment!

This first year of Tie-4-The Future is just getting off the ground. That means now is the time to jump in and make an impact.

Fly Tying at Walking Mountain Science Center

Many chapters are already hosting fly-tying nights or informal tying sessions—and if your chapter isn’t yet, this is a perfect reason to start! A Tie-4-The Future tying event can be:

  • A chapter fly-tying night

  • A pop-up event at a local shop or brewery

  • A casual gathering for new and seasoned tiers alike

  • A great way to welcome new members or reconnect with longtime ones

No pressure, no perfection—just flies tied with purpose.

Why It Matters

The flies you tie don’t just fill boxes—they help spark curiosity, build skills, and create lifelong connections between young people and our waters. Through our Colorado Education Programs these flies become tools for learning, inspiration, and conservation.

Ready to Get Involved?

Gather your materials, rally your chapter, and start tying! When you’re ready, mail your flies to:
