Water Conditions: High and roilly with snowmelt. Dredging the deep, slow pockets might produce a fish or two, but the upper Sac is definitely not your best bet right now.

Fishing Conditions & Hatches: Nymphing with Black Midges, P.T's, Red Copper Johns, and especially Baetis Nymphs patterns, such as Micro Mayfly Olive and Eric's Lightnin' Biot Baetis! Nymphing the slower-moving pools is going to produce more fish this time of year, but there have been some good baetis hatches with possible dry fly action in the afternoons.

The Fly Shop's Tips: With low snowpack this year, the Upper Sac should be fishable earlier than most days, and there should be some great dry fly fishing in May and June.
