Manzanita has slowed somewhat and there is a lot of pressure. The main deal right now are Damselfly nymphs fished under indicators. You may see some Glossosoma Caddis coming off towards dark. Zebra Midges, Balanced Damsels and #14 - 16 PTs fished under indicators or on an I-Line are good methods right now.

Pay attention to the special regulations here, especially where you can and can't fish. Barbless hooks, artificial lures, catch and release. Make sure you inquire at the park entrance.
