• Where to Fish on Upper Knob Lake

  Without a survey to go on, judge depth from how the bank falls away. Read the surface for the wind lane, then fish the edge of it. A natural lake fishes on cover, and cover here means weed and timber. Records held for Idaho County cover rainbow trout, Chinook salmon, cutthroat trout and bull trout. Protected fish appear in the records for this area, so treat the list as information, not an invitation. Work Upper Knob Lake in sections rather than trying to cover it.

• Seasonal Patterns

  Long-run averages give July about 52°F and December about 20°F. Spring and autumn carry the fishing; summer and winter test it. The lid usually goes in mid May, which opens the strongest weeks of the year. Climate averages put the opening at about mid May and the closing near mid November. Just after the ice goes and just before it returns, the fishing lifts. On Upper Knob Lake that shapes the whole year.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. Public data shows nothing built here, so treat the whole approach as informal. For the trout, small spinners and a box of nymphs cover both approaches. Local rules can differ across the county line, so check where you stand. Close seasons apply to some species and not others. Middle Knob Lake sits 0.6 miles off and takes the overflow. Confirm before you fish Upper Knob Lake.
