Airborne radar reveals lake trout hideouts

LiDAR came to fame finding lost cities hidden under centuries of jungle overgrowth. Turns out, the repurposed laser technology makes a pretty good fish-finder, too.

That makes it easier to spot schools of spawning lake trout, something fisheries biologists must do to protect the dwindling populations of cutthroat and bull trout that the invasive lakers eat. Instead of spending days scouting with gillnets from boats, a LiDAR-equipped airplane can survey all of Yellowstone Lake’s 87,000 acres in a few hours.
