 Starway Stone Ward, an invasive species, has been confirmed in Cass Lake. The Forest Service announced a closure order near the Knudsen Dam to reduce the spread and prepare for treatment. Mel Meyer has more from the Chippewa National Forest. The Knudsen Dam boat access, campground and parking areas will be closed until January 1st to reduce the spread and for a previously planned construction project. The boat motors tear up the algae and then the little segments can populate themselves elsewhere. The Forest Service says that will work with the Minnesota Department of Natural Resources, which will use herbicides to kill off the species. It's not high fishing season right now. If we have to have this infestation, this is a good time to find it and treat it. The plan created by the Forest Service and its partners may look like the one used on Turtle Lake, which has had mixed results. Bruce Ansbach will be assisting both groups with the project. He also oversaw the work on Turtle Lake and the dredging process used there. So with the equipment in there, they kind of push some up next to the drift curtain and then they couldn't vacuum up right next to the drift curtain. Workers have since applied herbicides twice to kill off remaining fragments, which has worked in other bodies of water like Upper Red Lake. It actually worked really well because it's an enclosed harbor area and the stuff is practically gone. The size of the infestation provides hope for eradication. We haven't found any more, except for at the Knudsen Dam area, so that's very hopeful. In Bemidji, I'm Al Meyer, Lakeland News. Zebra Mussels, another invasive species, was found in Cass Lake in 2014.
