In 2013, Maryland Department of Natural Resource biologists discovered hydrilla – a fast growing invasive weed that can negatively impact recreational opportunities in the southern portion of Deep Creek Lake. The department convened a nationwide expert panel to evaluate all potential hydrilla control strategies and implemented a multi-year herbicide program. Since 2014, the department has been treating the lake-bottom where hydrilla has been found with small amounts of herbicide each year to exhaust all of the tubers (reproductive structures that generate new plants). The treatment program has been successful since its inception in 2014 and is planned to continue during the summer of 2018. The 2018 planned herbicide treatment dates are as follows:
June 4 – 1st hydrilla treatment
June 26 – 2nd hydrilla treatment
July 24 – 3rd hydrilla treatment
Aug. 21 – 4th hydrilla treatment
Treatments are usually conducted on Tuesdays, however the first treatment is scheduled for Monday June 4, 2018. These dates are subject to change due to weather conditions. The Department encourages lake residents to sign up for email updates. For questions about the Hydrilla Control Program, please contact Mark Lewandowski at Mark.Lewandowski@maryland.gov.
