Invasive Lake Killers:
One Minnesota lake community came together with the DNR (Department of Natural Resources) to get an early jump on this invasive lake killer. Grand Lake, near Rockville MN, caught their invasive Stonewart early enough to be able to contain it by hand pulling it to control it. Researchers say that 13 Minnesota lakes have been exposed to the Starry Stonewart. The likelihood of that number doubling could be very realistic with the large number of recreational boaters and fisher people that bounce from lake to lake. On many of the other lakes, hand pulling is not feasible because of how large the Stonewart blooms have spread.
The lake systems that have large blooms are somewhat controlled by using algaecides, chopping, by mechanical means and using copper herbicides. None of the current methods have been overly successful. The best way to stop the spread of invasives, whether it be aquatic plants or aquatic animal species, is to clean and empty all water out of your boat before and after usage. Five or ten minutes of preventative measures could save decades of costly maintenance for your local lakes. Let's all do our part to keep an eye out for invasive species while out on our local lakes.
Recent Drainage Inspections – week of May 13 – May 17:
Special note: no blog next Monday, as it is Memorial Day. Enjoy the upcoming holiday! The DrainageBlog will be back Monday, June 3.
We are seeing a fairly large number of tile repairs coming in this time of year. The unfortunate thing is we are still trying to work through our repair list from last year, 2018. Please report issues you see on our public drainage systems, whether it’s a tile system or an open ditch system. The repairs are usually fixed in the order they are received, so please don’t wait to let us know about issues you observe on public drainage systems, as the list grows daily.
We require that all repairs to a county drainage system (tile or open ditch) be authorized by one us in the drainage office, either Craig or myself, before any repairs are made.
