Bighorn River Fishing Report

Filed under: Fishing Report

 *Current Report*
The river is fishing great. The warmer weather is bringing a few more
people to the river, but there’s lots of room.

*View of the Aquarium – from my office
Boat traffic is picking up and should increase through the week but looks to be mostly locals. Rover was fairly busy over Easter, but has dropped back off.

*Best Techniques*
From 10am -7pm look carefully for quiet rises along slick edges of riffles and quiet flats. Rising fish may not be visible from all angles. Patience may pay off as you may see only sporadic rises for BWO’s but fish will continue to look for them. The steadier rises may require matching size of bugs closely; otherwise try a size or two bigger. Also try BWO pattern for midging fish, they sometimes look for them all day. Best to approach from below, but adjust your position for current and lighting. Nymphing w/indicator in shallow water has been extremely productive. Start light and use stealthy indicators. Look for shelves with slow to moderate current and soft edges of riffles. Also seams along heavy water for biggest fish. Adjusting weight and length of rig is important to keep your fly close to the bottom. Mending carefully to keep it drag free, will get the most action, look closely as strikes are mostly very subtle, any pause or twitch deserves a response. (set the hook!)

*One-Week Fishing Forecast*
We have another winter storm forecasted  for this week. Starting tonight through Saturday the 18th. Snow 2 to 8 inches and 1.25 inches in addition to the snow!!! Highs in the upper 30’s Low in the upper 20’s to low 30’s.

*River Sections*
0 to 3 mile  Access  – Best Dry Fly Fishing – Great Nymphing

3 to Bighorn Access – Dry Fly activity increasing, should just get better, great nymphing, Best bet for streamers. Soap Creek starting
to run so water clarity drops the farther you go down to 13 mile (Bighorn Access).

Bighorn Access to Mallards Landing – Not much due to water clarity

*Hatch Info*
With higher water this past week rising fish limited to peak hatch times 1pm-3pm for BWO’s and 7pmtil dark for midges. BWO patterns still effective over some midging fish.

*Hot Fly Patterns*
