Streamers

Streamers and wets for stained water, banks, and low light. This is not a claim that streamers are "on" today.

No catalog patterns in this group yet. Use the hatch chart and the river guide.

Setup

4X and 5X cover most nymphing. 4X on dries until the fish get picky, then 5X. A 3.0–3.8mm tungsten on the point and a lighter dropper is a default until you see the water. Tight-line the near bank and the heads of pockets. Use an indicator only when you need to search water you cannot euro.

FAQ

What flies work on the Cache La Poudre River?

Start with BWO Sparkle Dun and BWO Parachute, then match size to the hatch chart for the month you are standing in. The Cache La Poudre River does not need a 40-pattern box. It needs the right size on the insect that is actually in the drift.

When is the best time to fly fish the Cache La Poudre River?

The editorial window we list is April, May, July, August, September, October. That is a planning month range, not a guarantee. Shoulder months can fish well if flows and water temperature cooperate.

Do I need a guide on the Cache La Poudre River?

Colorado has walk-up wade water and, on some sections, float water. A guide is worth it for a first float or a technical tailwater. A hatch chart and a gauge are enough for a first wade if you already nymph. We list local guides and shops on this page when we have them.

Where can I see live flow for the Cache La Poudre River?

The Cache La Poudre River has no USGS gauge mapped yet. The river page says so; we are not guessing a number. Access notes and the hatch chart are on that page. We do not publish other people's spots or fish counts.

Is this a report of what's working now on the Cache La Poudre River?

No. Executive Angler does not publish other anglers' catches, GPS, or a crowdsourced hot fly. This page is hatch-chart patterns plus catalog flies. Presence on the river page is gauge and weather only.
