Overcast days can be awesome. With lots of weeds, precise casts are needed to place your fly between the weedbeds. Long fine leaders and stealth are needed to fool these wary rainbows and browns. Keep wading to a minimum to save this fragile watershed. Manzanita Lake, Lassen Park Clear, cool.
Fishing is fair.
With cooler weather, morning and evening fishing is slowing. Fish midge emergers with a midge pupa dropper from mid-morning on. Walk the shoreline and look for cruising fish. During the day try damsel and callibaetis nymphs. In the afternoon, use streamers on sinking lines.
