Alturas Lake in Blaine County: How and When to Fish It

• Overview

  Alturas Lake lies within the bounds of Blaine County, Idaho. The ground round it is mixed forest. At 838 acres this is proper open water rather than a pond. Around 4.8 miles of bank, which is a long day on foot. Size puts it in the front rank of our Blaine County list. Sun Valley sits 30 miles from here and is the nearest stop. It is 70 miles to Boise, the nearest city. Rules here are straightforward: one county, one set of rules.

• Where to Fish on Alturas Lake

  Without a survey to go on, judge depth from how the bank falls away. A soft bed grows weed late into autumn, which keeps fish shallow. Where the bottom changes texture, fish gather; find that line. County-wide records name rainbow trout, cutthroat trout, Arctic grayling and sockeye salmon. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. On Alturas Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  The warm month here averages 53°F; the cold one sits at 17°F. The year runs cold to warm and back, with clear transitions. Ice is part of the season here, ending near mid May. Climate averages put the opening at about mid May and the closing near mid November. The middle of summer slows a little, with dawn and dusk carrying it. Plan any trip to Alturas Lake around it.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. A campsite is mapped about half a mile away, which makes an early start easier. Toilets show in mapping about half a mile away. Light line and small metal for the trout; a fly rod earns its place on calm evenings. State or provincial rules still apply whatever the bank status. Keep proof of licence with you rather than in the car. Perkins Lake at 1.4 miles is the sensible second choice. Check the current arrangement for Alturas Lake.
