Idaho high mountain lakes in the Fishing Planner
The IDFG Fishing Planner lists 1,261 named high mountain lakes, from the Selkirks and the Bitterroot divide to the Sawtooths, the Pioneers and the Lost River Range. Most are reached by trail, and many are stocked with fry on a rotation. A lake gets a page here when the Planner prints enough for one (75 do); the rest are named on their county page.

Answers
Idaho high mountain lake questions
How many high mountain lakes does Idaho list?
1,261 named lakes in the IDFG Fishing Planner.
Which county has the most?
Idaho County, with 442.
Which IDFG region has the most?
Clearwater Region, with 436.
Are they stocked?
Many are, usually with fry on a rotation; each water page with stocking rows shows the dates IDFG prints.
What limits apply?
The region table for the lake’s IDFG region, unless the lake prints its own rules.
Why do only some have a page?
A page needs enough facts of its own; the others are named on their county page with acres.
How are coordinates set?
From the IDFG water id, which encodes a point near the lake outlet.
Can I camp at these lakes?
Most sit on national forest or wilderness land; check the forest’s rules before a trip.
