TOWN OF HERMAN: Leopolis Pond Rapid Response


The Town of Herman proposes to control Eurasian Watermilfoil in the Leopolis Pond by implementing control measures during the period 2015-2017. The project elements and deliverables are specified in the Town of Herman\2019s Aquatic Invasive Species Emergency Response Grant application, dated January 31, 2014. The project includes conducting Point Intercept surveys using the DNR Aquatic Plant Treatment Evaluation Protocol ,in addition to lake bathymetry mapping, both being performed by the Department of Natural Resources; controlling Eurasian Watermilfoil with a drawdown in combination with hand pulling; and implementing an aquatic invasive species prevention and control strategy that includes soliciting the in-kind volunteer work that is identified in the grant application. Annual progress reports and a final report summarizing the 3-year project will be provided to DNR. Any publications produced as part of the project will incorporate the \201CStop Aquatic Hitchhikers!\201D\2122 brand (partnership details can be found at: If consultant is to provide the final report, it is recommended that the Grantee provide the DNR Aquatic Invasive Species Coordinator with a draft for comment on report adequacy prior to making final payment to the consultant. By accepting this grant, the Town of Herman accepts all financial and administrative aspects of the agreement regardless of any cooperative agreements with any other entity. DNR will be provided both paper and electronic. pdf copies of the final report along with, or prior to, submission of grantee\2019s final payment request.

Reports and Documents
In September 2016, Leopolis pond initiated a full drawdown. In April 2017, the pond was brought back up to full capacity. A drawdown can be very effective when properly conducted with all entities involved. The effects can last for three or more years. A drawdown may allow the sediment to compact. As a driver of disturbance, drawdowns may increase native plant diversity by “flushing” out the dominant Eurasian watermilfoil. It is suggested that a drawdown occur in Leopolis Pond every 5 years. However, it would be beneficial to engage all stakeholders of the lake to come up with an agreeable method.
