Caswell Lake Fishing near Susitna North, Alaska

• Overview

  Caswell Lake is one of the Matanuska-Susitna Borough listings for Alaska. Around the bank it is pine and birch. It runs to roughly 154 acres — big enough to hold fish away from the bank, small enough to learn. At about 3.3 miles of edge, most people work one arm at a time. Some 11 miles away sits Susitna North, the nearest settlement. Beyond it, Willow at 19 miles and Houston at 27 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Caswell Lake

  Nothing we hold settles how deep this runs. Look for the band where the shallows give up and the bottom falls away. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Matanuska-Susitna Borough list rainbow trout, Coho salmon, sockeye salmon and longnose sucker. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Read Caswell Lake for ten minutes before the first cast goes out.

• Seasonal Patterns

  Expect July to average close to 58°F, with January the cold end at about 9°F. A full turn of seasons, with the strongest sport on either side of summer. Ice-out usually falls in late April, and the weeks after it fish hardest. In an average year the thaw lands around late April and the freeze near late October. The shoulder weeks of the open season are the productive ones. Expect Caswell Lake to follow that timing.

• Tackle & Baits

  The access position is unclear from public sources. This is a natural basin, not a dammed one. No made access is recorded, so a short walk in is the likely arrangement. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Rules differ from one water to the next round here. Fishing rules and camping rules are set separately here. Emil Lake at 5.8 miles is the sensible second choice. Confirm before you fish Caswell Lake.
