April 14 to April 18
George and Christine Fieldings are from New York City. On a recent visit to Forrester’s Bighorn River Resort they landed some very big fish on a midge pattern. Fishing was excellent all week and is best if you were fishing between Noon and dark (8:45).
We’ve had some of the best dry-fly-fishing of the year so far.
Right now the peak time for dry-flies is from 6 p.m. until 8:45 p.m.

Excellent Dry Fly Fishing and Nymph Fishing

Boat traffic and walk in wade fisherman are picking up, of course busier over the weekend
*Best Techniques*
From 11:30a.m. – till dark 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. From 7 pm till Dark (8:45pm) Midges are creating pods of feeding fish.
*One-Week Fishing Forecast*
This is going to be one of the best weeks to be on the Bighorn this year. Dries fly fishing will do nothing but pick up. All week the highs are to be in the mid to upper 70’s. This could cause the wind to blow some but has usually been dying down a couple hours before dark. Forecast is for winds 5 to 15 mph through the week.

0 to 3 mile Access – Best Dry Fly Fishing – Great Nymphing
3 to Bighorn Access – Good Dry Fly activity, great nymphing, Best bet for streamers. Soap Creek starting to effect the water clarity the farther you go down to 13 mile the more it looks like chocolate (Bighorn Access).
Bighorn Access to Mallards Landing – Not much due to water clarity, Nymphing is ok.
*Hatch Info*
Peak hatch times 1pm-3pm for BWO’s and 7pmtil dark for midges. BWO patterns still effective over some midging fish.

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

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.

Actually I can see all the way to the Hot Dog Hole! No leaves on the trees. Boat traffic is picking up and should increase through the week but looks to be mostly guides and locals.

*One-Week Fishing Forecast*
Should be a great fishing week. At this time wading for rising fish the only option, Both wading and floating productive while nymphing.Streamer fishing is spotter but some cloudy days can be good, banks and deep pools. Cloudy days better for rising fish, but some have been in bright sun.
