Fishing at Upper Aero Lake, Park County, Montana

• Overview

  Look for Upper Aero Lake in Park County, Montana. This is pine and birch country. The water covers some 227 acres, so pick a bank rather than trying to cover it all. Roughly 2.5 miles of bank means you can walk to a fresh area when one goes quiet. Few waters listed in Park County are bigger. Red Lodge sits 29 miles from the bank. Absarokee lies 33 miles off, Columbus another 45 miles. There is no boundary nearby to worry about.

• Where to Fish on Upper Aero Lake

  We hold no depth figure for this one. On a natural lake the weed line and the shelf beyond it do the work. A soft bed grows weed late into autumn, which keeps fish shallow. Reported across Park County: rainbow trout, brook trout, california golden trout and brown trout. County data is a starting point rather than a guarantee. The shape of Upper Aero Lake rewards a slow walk along one bank.

• Seasonal Patterns

  August is the warm end of the year here, averaging about 48°F, while January sits near 13°F. A full turn of seasons, with the strongest sport on either side of summer. Count on hard cover from midwinter, and open water from mid June. Climate averages put the opening at about mid June and the closing near late October. The weeks after the thaw and the ones before the freeze are the strongest. That is the shape of the year on Upper Aero Lake.

• Tackle & Baits

  Public data does not answer the access question here. It formed naturally, so levels move with rainfall rather than with a gate. Nothing is mapped in the way of a ramp or car park within a short radius. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Season dates differ by species, so read the table. Access can change hands, so last year's answer may not hold. Leaky Raft Lake, 0.7 miles away, makes the obvious fallback.
