A planned herbicide treatment at Lone Star Lake has been postponed for a week.

Karrey Britt, a spokeswoman for the county, said the Douglas County Public Works department will now treat the lake for Eurasian watermilfoil, an invasive plant species, on Aug. 14 and 15 if weather permits. Water activities in the lake will be prohibited for 24 hours after the treatment is complete.

The treatment was originally planned for Wednesday and Thursday, but it was postponed because of expected rain on those days, Britt said.

Crews will use the herbicide Navigate, which is a granular substance that sinks to the bottom of the lake, according to the county. Park visitors and residents are also encouraged to keep their pets out of the treated portions of the lake for 24 hours after treatment, the county said.
