Oregon's Lost Lake has scientists wondering where the draining water goes.

Every winter, the lake fills up. Each spring, it drains. Where the water goes, no one knows for sure. The leading theory is that it replenishes ground water, and feeds springs.

Water from Lost Lake drains down one of the many lava tubes scattered throughout the Central Oregon Cascades. The water is most likely seeping into the subsurface below and refilling the massive aquifer that feeds springs on both sides of the Cascades.
