Aquatic Invasives Grant
Aquatic Invasives Early Detection and Response
Grant report of Lone Stone Lake 2016.
The AIS Monitoring Control Report for Lone Stone Lake.
Lone Stone Lake is a 171 acre, drained, headwater lake in Oneida County, with a maximum depth of about 30 feet. The invasive Eurasian water milfoil (EWM) was first reported in the lake in 2011. Following consultation with the Wisconsin Department of Natural Resources (WDNR) and Oneida County AIS Coordinator Michele Saduaskas, the Friends of Lone Stone Lake (FLSL) contracted Onterra, LLC to complete a EWM survey in late summer of 2013. This 2013 survey provided data on the extent of EWM within the lake, which was used to develop a project strategy during the winter of 2013/2014. It should be noted that although the EWM was believed to be pure strain, samples of EWM were collected during this survey and sent to a lab in Michigan for genetic testing. The testing confirmed the plants were pure-strain Myriophyllum spicatum (EWM) as opposed to a hybrid species between northern water milfoil (Myriophyllum sibericum) and the aforementioned EWM. This hybrid species (termed HWM) has been confirmed in several Wisconsin lakes and may complicate management due to its aggressive nature and suspected decreased susceptibility to herbicides. The FLSL were awarded a three year Aquatic Invasive Species (AIS) Early Detection & Response in February of 2014 to initiate monitoring and hand-removal actions in 2014-2016. This report discusses the second year of monitoring and control under this grant-funded project and concludes with recommendations and strategies for the last year of the three year project, 2016.
On July 18th, 19th, and 20th, Aquatic Plant Management LLC (APM) Conducted hand removal services of Eurasian Watermilfoil (EWM) on Lone Stone Lake in Oneida County, WI. Our divers spent a combined total of 58.5 hours on the water and were able to successfully remove 97.5 cubic feet of EWM from the lake. As per Onterra LLC's request, we worked our way around the lake, targeting small plant colonies and clumps of plants first, before moving on the single or few plants remaining within the EWM control area. After spending the majority of the day on July 18th targeting the high priority sites, we then spent the remaining time on the lake mainly focusing on site C-16, as this site had the highest number and concentration of single EWM occurrences. It should be noted that site C-16 had a very high number of plants in the 1-3" height range compared to any other site on the lake.
