TranscriptionSegment 78: Eurasian Water Milfoil Air Date: August 3, 2004 Tease @ 24:49 "A noxious weed is costing homeowners in the Tahoe Keys tens of thousands of dollars a year to deal with.I'm Shelly Purdy, I'll tell you what it is in tonight's Lake Tahoe Report." Anchor Intro: Noxious weeds have become a big problem throughout the west, and Lake Tahoe is certainly not immune to the problem. In tonight's Lake Tahoe Report, Shelly Purdy takes a look at the very invasive and very destructive Eurasian Water Milfoil. ((Take PKG)) ((Nats lawn mower boat cutting weeds)) ((Track 1)) Here at the Tahoe Keys on the lake's south shore, the lawn mowers run continuously throughout the summer. What's so different about these lawn mowers though, is that they're working underwater…cutting a noxious weed called the Eurasian Water Milfoil. ((sot @ 15:30 Susan Donaldson, University of Nevada Cooperative Extension Water Quality Specialist)) "Eurasian Water milfoil is what we call an exotic invasive weed. Exotic meaning it doesn't come from north America. It comes from Eurasia. Invasive meaning once it gets in a water body it grows like crazy and takes over and displaces all the other plants that might have been there previously." ((Track 2)) And that's proving to be a big problem at the Tahoe Keys. Without the lawnmowers the boats wouldn't be able to get through the channels at all. ((sot @ 13:11 Greg Trischler, Water Department Manager, Tahoe Keys)) "It gets into the props and then stalls the engines and they wouldn't be able to get to the lake. It would depreciate the value of the homes." ((Track 3)) But unfortunately, mowing is only a temporary fix to this growing problem at Lake Tahoe. ((s/u @24:01 Shelly Purdy)) "Eurasian Water Milfoil spreads very easily and can be found in just about every marina around Lake Tahoe and now it's event in Emerald Bay." ((sot @ 17:17)) "Eurasian Water Milfoil spreads by little plant parts. When a boat encounters a vine and a propeller churns it up and breaks up the pieces those pieces will actually drift and float, grow roots and grow in another location." ((Track 4)) And since the plant loves clear, shallow water…places like marinas and Emerald Bay are the perfect habitat for it to grow. With the Lake Tahoe Environmental Education Coalition, I'm Shelly Purdy for KOLO NC8. Anchor Tag: Researchers are testing various methods to try to find a way to control the Eurasian Water Milfoil in Lake Tahoe. Once such method uses water circulators to stir up the water around the plant since the weed doesn't grow very well in moving water. WHAT CAN BOATERS DO? Reverse Propeller, Check boats before putting them in
