Water cradled through the rugged topography of brook trout country creates some obvious strongholds. Brookies like cold oxygenated water flowing over their dark hides. While foraging squaretails work fast water, they spend their leisure time lingering in deep pools at the base of falls, rapids, and riffles. In slower sections, cover such as undercut banks, overhanging trees, and submerged logs provides refuge from sunlight and predators, including anglers. When approaching a potential hideaway, bear in mind that brook trout are edgy and easily spooked.
Trout grow increasingly wary with age and experience.
With fish generally facing upstream, there's wisdom in sneaking up behind them by making your way against the current. This doesn't mean to lumber recklessly along. Stealth is crucial. Keep a low profile, step lightly to minimize vibration, and try not to cast a shadow over the trout zone. If you're in a canoe, drop anchor well above the area you want to fish.
