How to fish Loomis Lake: mid-depth structure water

With 50 feet at its deepest, the fish-holding structure is the mid-depth contour: drop-offs, points and inside turns between the shallows and the basin. Use the 10 mapped depth bands to find where contour lines pinch together, which marks the sharpest breaks, and work those edges first, especially early season and again in the fall as fish follow bait between depths.

Ice fishing on Loomis Lake

Loomis Lake is a classic ice-fishing depth: enough water to hold fish all winter without the long freeze-up of a deep basin. Start on the deepest mapped hole at first light, then work the breaks where contour lines tighten. Mid-depth flats near the basin edge produce through midday. Always verify ice thickness locally before walking out.
