Sunrise Fly Shop-Big Hole River Blog

The Big Hole has bounced back from the last recent bump in flows.  We have 2 feet of visibility, dropping water and the fish are looking up for Skwalas.  Our best dry fly fishing has been from Maiden Rock all the way to Notch Bottom.   Look for your best dry fly action to be from 1:00 to 6:00pm.  This week will be prime time for the Big Hole Skwala hatch.  Slow moving streamers have also been getting it done for us.  The best streamers of choice have been Coffee buggers, Natural Slap and tickles and Yellow/black beldars.

The Beaverhead River has been fishing ok as of lately.  Remember the river is closed from the Dam to Pipe Organ until the 3^rd Saturday in May.   We have had some dry fly fishing on the overcast days with Blue winged Olives.  Sow bugs under an indicator with a blue wing nymph has been keeping our rods bent.  Below Grasshopper we have been able to move some nice fish on streamers.

Over the weekend, we had our fist push of water.  On Monday the Big Hole climbed to a little over 2000 cfs, but the weather cooled off again and the river is back down to 1400cfs and the river is continuing to drop.  The water clarity has improved greatly in the last 48 hours, and we are back to about 2 feet of visibility.

Fish have still been coming up for Skwalla dries, but greater numbers of fish have been caught using nymphs.  Baetis nymphs, Stone Fly nymphs, and San Juan worms have still been the best nymphs. 

Remember, our spring special ends May 15^th.  $500.00 per person for three nights lodging and two days of guided fishing!

Everything here on the Big Hole seems to be staying about the same.  The weather pattern seems to be holding steady with daily highs in the high 40’s and lows in the mid 20’s.  The mountains have been getting moisture almost every day, but the river valley has been staying relatively dry.

For fishing this means that we have been seeing, and will probably continue to see about the same conditions.  The river flows are getting a nightly bump, but dropping during the daytime hours and averaging around 1200 cfs.  The river temps are ranging between 37 degrees and 45 degrees.  We’ve still been getting fish to come up and eat Skwallas with good frequency, while the nymphing with Stone Fly Nymphs, San Juan Worms, and small Mayfly Nymphs has been very consistent.  We’ve also noticed that the fish have been chasing streamers a little more aggressively in the last few days.

Everyone knows the feeling, the itch to experience the first dry fly fishing of the year on Southwest Montana freestone rivers.  The first spring hatch, a.k.a. some of the best dry fly fishing of the year is the Big Hole River Skwala hatch. 

The Skwala stonefly makes it’s appearance as spring and the end of winter collide.  On the Big Hole River this is around mid-April.  As the ice breaks free from the freestone rivers and water warms between 45-48 degrees for a consistent period of time, skwalas start to migrate to the banks of the Big Hole River to hatch.  The Skwala is a size #8-#10 stonefly with an olive colored body.  Like most stoneflies, Skwalas crawl onto rocky and brushy banks to hatch.  Unlike most stoneflies though Skwalas rarely fly in the air.  These stoneflies tend to crawl across the water when they lay their eggs.  Skwalas are hard to see in the water as they skitter with there wings closed on the surface.  Trout in the 16 - 22 inch range are taken on the dry fly during this hatch.

Since this is the first hatch of the year with a sizable meal, trout tend to key into Skwalas pretty quickly.  These stoneflies are not in the same abundance on the Big Hole as Golden Stones or Salmonflies on the Big Hole, but there are enough of them to make for some great dry fly fishing.  This is a great time to experience trout feeding with fury, as they eat their first stoneflies of the season.
