July Fishing on the Bighorn River

SEASONAL GUIDE

What to expect in July

July is often a good month for PMDs and caddis. Nymphing can be productive, and rising fish may give you a chance to switch to dries. Choose your approach around the flow, wind and time of day.

Flows may remain high in a wet year or begin dropping in a more typical year. Keep a closer eye on water temperature and weeds later in the month.

How to rig

Start with a 7–10 foot rig, then adjust for the depth and speed of the water. High releases may call for more length and weight along bank seams.

KEEP IN MIND

Before you head out

Before changing flies for a rising fish, watch what it is taking: nymphs, emergers, duns or spent adults.

An early start often gives you calmer wind and good morning activity. Bring plenty of drinking water and sun protection for a long float.
