About Saint Mary Lake
Anglers know Saint Mary Lake as one of the lesser-trafficked lakes of Montana, United States. The standard playbook on a lake this size is to start shallow at first light, work outward toward deeper water as the sun climbs, and circle back to the shallows before dusk. Surface activity at Saint Mary Lake is a useful tell — boils, swirls, and rising baitfish point straight at the predator zone.

Fishing Techniques
- For Lake char
Target lake trout in deep, cold water during the summer months, focusing on areas with structure or drop-offs; use a fish finder to locate schools of fish and baitfish.
- For Mountain whitefish
Use light line (2-4 lb test) for better presentation and sensitivity, and fish near the bottom in runs and riffles.
- For Rainbow trout
Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.
