Description

Located off Idaho Highway 30 near Malad River Gorge Dam. See the unique geology of one of the world’s largest aquifers.

Layers of volcanic rock form a porous underground sponge that collects a vast quantity of water, releasing it in natural springs.

Idaho Power operates two hydroelectric projects in the upper reach of the river. The company has built two fish ladders to help resident rainbow trout migrate past the projects to spawn.

Day use is free.
