Long Mountain Lake, Idaho: Fishing Spots and Seasons

• Overview

  Long Mountain Lake sits within Boundary County in Idaho. Land around it is rolling bush. Small even by pond standards, it rewards one careful line. Most waters listed here for Boundary County are larger. The closest town, Bonners Ferry, is 17 miles distant. Then Creston, 19 miles, and Ponderay, 37 miles. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Long Mountain Lake

  We hold no survey for this water; read the slope of the shoreline instead. Read the surface for the wind lane, then fish the edge of it. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Boundary County include rainbow trout, cutthroat trout, brook trout and Arctic grayling. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. On Long Mountain Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  August is the warm end of the year here, averaging about 55°F, while January sits near 18°F. Seasons are distinct, and each one fishes differently. Hard cover is dependable here; it goes around early May. Ice clears near early May and comes back about mid November in a typical year. The shoulder weeks of the open season are the productive ones. Long Mountain Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Public sources are silent on who controls the bank. Mapping is blank for access, so scout the approach before committing the car. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Parking is often the real limit rather than the bank itself. Close seasons apply to some species and not others. Trout Lake, 1.2 miles away, makes the obvious fallback. Check the position on Long Mountain Lake before loading the car.
