Hatch Status

Rain will bring off increased activity from PMDs, Blue-Winged Olives, and Mahogany Duns.

Conditions

Flows have settled at around 6,000 cfs at the Lorenzo gauge as of August 26, running above normal for August. A cooling pattern with rain and showers will push activity on PMDs, Blue-Winged Olives, and Mahogany Duns. Expect fish to respond more aggressively to dry patterns, foam, and terrestrials when cloud cover thickens and temperatures drop. Streamers are worth considering if conditions stay unsettled.

Gauges

Techniques

  • Mutant Golden Stones, hoppers, beetles, and ants are all worth having tied on.
  • Streamers should fish well in light conditions.
