The following stories (click on bold blue links below) were salvaged from the Quiet Lakes blogsite (discontinued in July 2018) in order to preserve institutional memory with respect to the appearance of Hybrid Eurasian Water Milfoil in Lost Land Lake. This invasive plant species became established in Lost Land Lake despite expensive and time-consuming efforts to inspect watercraft at public boat landings.
The Wisconsin DNR strongly encouraged and largely funded QLIA’s program to inspect watercraft going in and out of public points of access on the Quiet Lakes. Called the “Clean Boats, Clean Waters” program by DNR, this strategy for preventing the spread of aquatic invasive species may be effective on some waters, but it was ineffective on Lost Land Lake. Why? We conservatively estimate that at least half of the watercraft going in and out of Lost Land Lake do so at five or more resorts (or former resorts) where boat ramps built long ago are maintained for the convenience of guests or condo owners. Nobody knows where Hybrid Eurasian Water Milfoil was first introduced into Lost Land Lake, but part-time inspection of one moderately used public boat landing (on Landing Camp Bay) was not likely to prevent the spread of aquatic invasive species into our lakes. It would not have been affordable or practical to continuously monitor all the private points of boater access in addition to the one significant public access.
Our inability to continuously monitor all points of boater access led to the inevitable…
Our conscientious resort operators have every right to provide agency-approved boater access to their guests. But we should learn from past experience that part-time monitoring of our only significant public boat landing on Landing Camp Bay will not prevent future invasions (or exports to other waters) when there are so many other boater access options. We need a broader strategy for control of aquatic invasive species.
