Mid-morning to early afternoon is still the best time. Still fishing deep with larger attractors and streamers.Big fish are still on the move and can be found with a little patience. Easier down lower where the water is dirty.
Most of the recent snow has melted, but the access roads are still wet and muddy. 4X4 is essential if venturing further up.
Be careful driving as the mud can be very slick and a tow is expensive!
