Hatch Status
Hatches of Mahoganies and BWOs, especially on overcast days.
Conditions
Late summer has the South Fork dropping fast: flows sit at 3,590 cfs as of September 4, 2026, with Palisades Reservoir at just 10% capacity. Water temperature is holding at 65°F, keeping trout willing to eat. Mutant stone flies, Mahoganies, and Blue-winged Olives are hatching, with hoppers doing damage in the afternoons. Try a foam or dry dropper rig and consider heavier line and bigger attractors near the edges as flows continue to fall and newly fishable pockets open up.

Techniques
- Hoppers and Terrestrials can be effective in the afternoons.
