On American Falls Reservoir that means starting tight and working out.

Winter locks it down, and mid March brings it back. From about mid March to around mid December, expect open water on the long-run figures. The first weeks of open water and the last are the ones to plan for. Time your trip to American Falls Reservoir by conditions rather than dates.

• Tackle & Baits

  Being publicly held, the water is generally open for fishing. Nothing built is recorded close to the bank here. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Some ground is open by custom rather than by right, so tread carefully. Little Hole at 2.2 miles is the sensible second choice.
