Rush Hour In Douglas County

A retired DNR official was at Grant Lake last month.  His eagle eye spotted an unwelcome visitor—flowering rush.

Grant Lake is near Holmes City.  You’ll see Grant next time you go shopping at Blade’s Store.

Flowering rush looks kind of pretty.  It has pink flowers on top.  But underwater, not so cute.  It has material that doesn’t produce flowers.  Left untreated the submerged growth can sprout up to four feet and overtake natural habitat and indigenous species.  Plus, it causes headaches for boaters trying to navigate open water.

The good news is that August 8th, Douglas County AIS Coordinator Justin Swart and DNR dude Mark Ranweiler went along with employees from an aquatic plant and algae control company to apply herbicide to stem the growth of flowering rush.

AIS Prevention Coordinator Justin Swart remarked,

“We are fortunate that this officer spotted the flowering rush in its earliest stages. Treating it now should prevent it from spreading in Grant Lake and potentially to other lakes in the county.”

Douglas County Emergency Management/Information Officer Julie Anderson added,

This is the first documented case of flowering rush in Douglas County. Eurasian milfoil and zebra mussels are two aquatic invasive species that have been documented on other lakes in the county. Starry stonewort is also a concern. Saturday, August 17, volunteers will be used to look for starry stonewort and other aquatic invasive species at public access points. Volunteers are still needed. The event, called Starry Trek, will begin at 8:30 a.m. and last until noon. A free lunch is provided. People may register at www.StarryTrek.org

To keep the spread of AIS to a minimum, the DNR reminds boaters to drain and clean your watercraft, and toss unwanted bait in the trash.
