Chemical treatment was applied to parts of Lake Zoar yesterday.  The herbicide targets control of the aquatic nuisance plants Eurasian watermilfoil and curlyleaf pondweed.  The treatment was applied in an area where there was regrowth after an application of Diquat earlier this year.  There are no restrictions for swimming, boating and fishing in treated areas, but for the next 3 days the water should not be used for drinking purposes or for irrigating turf and ornamentals.  There should not be used today for livestock or domestic animal consumption.  For the next 5 days there should not be used of treated lake water for irrigating food crops or production ornamentals.
