What AnglerTrove is

Local knowledge for five fly fishing states

AnglerTrove is an independent fly fishing resource for anglers in Colorado, Montana, Michigan, Oregon and Washington. We make two things: state Playbooks that help you plan a trip, and River Alerts, which keeps an eye on the river sections you fish.

Alongside them, our river guides, articles, gear advice and the Colorado Skill Test are free.

State Playbooks

Five states, five Playbooks.

Pick your state: each Playbook is written for its own rivers, seasons and rules.

All Playbooks

Each one is six PDFs in one download: the main guide with a chapter per river, river quick-info cards, a hatch calendar, a seasonal cheat sheet, a trip planner and a fly box checklist. From $6.99 per state. One-time purchase, instant download.

7-day free trial

River Alerts

Follow the rivers you fish

Follow the river sections you fish across all five states: current flow and water temperature where a gauge reports them, agency closures and advisories up front, and emailed reports and alerts when you want them.

  • Flow and water temperature Where a gauge reports them. Not every section has both.
  • A conditions rating on most sections From our data partner. Some sections are deliberately not rated and show measured conditions only.
  • Closures and advisories first Shown prominently, in the agency's words. Always confirm with the agency before you go.
  • Checked about every 15 minutes Not real time, and readings can be provisional.

7-day free trial, no card needed. Then $5.99 a month or $29.99 a year.

How agency notices appear

Closed by the agency

A mandatory closure is shown first, with the agency's notice. The conditions rating is not shown while it stands.

Restriction in force

For example, limited fishing hours during warm water. Shown with who set it and where to confirm it.

How it works

Plan, follow, then check before you go

  1. Plan with a Playbook

    Pick your state and use its Playbook to choose the water, the timing and what to bring.

  2. Follow your rivers

    Add the sections you fish to River Alerts for flow, temperature and agency notices in one place, by email if you like.

  3. Confirm, then go

    Check regulations, closures and current conditions with the agency before you drive. They always have the final word.

What is AnglerTrove?

A small, independent fly fishing publisher. It sells state Playbooks, is building River Alerts, and publishes river guides, articles and gear guides free to read. More on the about page.

What is in a Playbook?

Six PDFs in one download, written for one state: the main guide (the State Fly Fishing Playbook 2026, with a chapter per river), River Quick-Info Cards, a Hatch Calendar, a Seasonal Cheat Sheet, a Trip Planner and a Fly Box Checklist. Each is a one-time purchase, from $6.99. See the Playbooks.

Can I use River Alerts yet?

Yes. Start with a 7-day free trial, no card needed, for up to 3 rivers. After that it is $5.99 a month or $29.99 a year for up to 25 rivers.

Does River Alerts tell me whether it is safe to fish?

No. It shows measured conditions and the agency closures and advisories it knows about, checked about every 15 minutes rather than in real time, and readings can be provisional. It is information, not a safety guarantee. Always confirm with the agency before you go.

Which states do you cover?

Colorado, Montana, Michigan, Oregon and Washington. River Alerts covers 73 river sections across them. Each state has its own Playbook. Our written river guides cover Colorado so far.

Do I need an account?

Not for the Playbooks or the Skill Test: buying needs only the email address you pay with, so we can send your files. River Alerts uses a passwordless sign-in link, because it has rivers and settings to remember.

How do you make money, and does it affect what you recommend?

We sell our own digital products, and some links to retailers earn us a commission when somebody buys through them. Commission never changes the price you pay and plays no part in what gets recommended. The detail is in our affiliate disclosure and editorial policy.

Can I get a refund?

Yes. 14 days, no justification needed. Read the refund policy or get in touch.
