Clear Lake National Wildlife Refuge and the Modoc National Forest converge at the high desert borderlands of Northern California and Oregon. This landscape is defined by its complex hydrologic network, where the Lost River meanders toward the expansive Clear Lake Reservoir. Significant water management features, including the Willow Valley Reservoir and its associated spillways, highlight the region's historical reliance on irrigation and conservation at the turn of the 1990s.
