Hatch Status

Hatches of Mahoganies and BWOs, especially on overcast days.

Conditions

Water temperature is running 65°F with flows dropping steadily as Palisades Reservoir sits near critically low levels. As of September 10, flows were holding at 3,840 cfs at Lorenzo, a significant decline since the source report dated September 8. Overcast conditions favor dry fly fishing; expect Mahoganies and Blue-winged Olives mixed with hoppers and terrestrials. Consider Parachute Pheasant Tails, Schroeder's Parachute Hoppers, and Improved Winged K.C.'s Creatures to match the hatch.
