Monday 10/19 I hit the Merced in various places near the park entrance. Caught ~15 7 to 11 inch Rainbows. #14 Olive bodied Caddis seemed to be most productive, followed by #16 Parachute Pale Evening Dun. Big fish (if you can call a 11"er big) came on an #10 October Caddis version of a Corn Fed Caddis. Temps were good but the water was about as low as I have ever seen it. Any spot 3'+ deep held fish. All fish were on dries. Carried my nymphing rod into the 1st 2 areas, but never used it.
