Tips Fly Fishing on the Lower Colorado River

Seasonal Tip
Focus on deeper pools and slow runs where trout are conserving energy. Use longer leaders and lighter tippet for stealthy presentations.

Dry Fly
Midge hatches during sunny afternoons offer brief dry fly opportunities. Look for rising fish in calmer water and present Griffith’s Gnats delicately.

Nymphing
Double-nymph rigs with a Zebra Midge and a Black Beauty are highly effective. Use enough weight to get your flies down to feeding lanes in deeper water.

Streamer Fishing
Streamers like Woolly Buggers or Slump Busters can entice larger fish, especially early or late in the day. Focus on shaded areas and retrieve slowly.
