Kenai National Wildlife Refuge intern Kyra Clark rakes masses of the invasive waterweed elodea from the Soldotna-area Sport Lake on Tuesday, May 16. Behind her, staff from the Refuge, the Alaska Department of Natural Resources, and the Kenai Watershed Forum prepare to launch the two boats that will target elodea with the herbicides diquat and fluridone. Following Tuesday’s herbicide discharge into Sport Lake, Refuge biologist John Morton said there’s a three-day safety restriction on drinking the lake water, but none on swimming or fishing. He also cautioned against sprinkling the herbicide-treated water on lawns or gardens. A second round of diquat and fluridone will be put into Sport Lake in September, Morton said, to contnue killing elodea through the winter. (Ben Boettger/Peninsula Clarion)

Tobias Schwörer, a researcher at the University of Alaska's Institute for Social and Economic Research, produced this map of floatplane bases and destinations for his study of how elodea, an invasive waterweed, could spread through the state. Floatplanes are a significant spreader of the weed, fragments of which can lodge in their rudders and floats.
