Techniques & Conditions Notes
Flow is in a great fishable range. Standard nymphing rigs with an indicator or euro setup will work well. Target seams, tailouts, and deeper runs.
Rain is forecasted in the next 48 hours — flows may rise. Plan your trip accordingly and check conditions before heading out.
Ideal water temp for Weber River trout. Expect great dry fly opportunities during hatch windows. Dry dropper rigs work excellently — pair a buoyant dry with a trailing nymph 12-18 inches below.
Overcast skies today are perfect conditions for a BWO hatch. Watch for rising fish in slower flat water and tailouts especially in the afternoon.
Spring on the Weber means runoff is coming or here. Watch for the Skwala and Salmonfly hatches which produce some of the best dry fly fishing of the year.
