Fishing at Grimes Lake, Idaho County, Idaho

• Overview

  Idaho holds Grimes Lake, in Idaho County. Land around it is lake country bush. A pocket of water where every cast reaches cover. It is one of the smaller waters we list in Idaho County. Stevensville sits 14 miles from here and is the nearest stop. The big place round here is Spokane, 162 miles distant. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Grimes Lake

  Depth remains unrecorded, so treat the first session as a survey. On a natural lake the weed line and the shelf beyond it do the work. Bays and points beat straight shoreline every time on water like this. Records held for Idaho County cover rainbow trout, Chinook salmon, cutthroat trout, bull trout and brook trout. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Work Grimes Lake in sections rather than trying to cover it.

• Seasonal Patterns

  Temperature averages peak at 55°F in August and bottom out at 18°F in December. Hard water is a season in its own right here. Ice-out usually falls in early May, and the weeks after it fish hardest. Open water usually runs from early May until about mid November. Spring is short and heavy here; autumn is longer and steadier. Plan around that when you fish Grimes Lake.

• Tackle & Baits

  Our records carry no access rule either way. Public data shows nothing built here, so treat the whole approach as informal. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Rules for this water may differ from the county norm. Some stretches are reserved and marked as such on the ground. For a change of water, Storm Lake is 0.9 miles distant. Nothing here settles the position at Grimes Lake for certain.
