Important Treatment Information For Summer 2016: You received a treatment notice mailed to your address of record as filed with the township you live in, as required by the State of Michigan DEQ. This notice will provide information on herbicides that are used to manage invasive species in Sand Lake. If you do not receive this notice, please contact your township to make sure your mailing address is correct. A copy is here: 2016 Sand Lake Notice
Treatment dates are approximate due to the need for proper weather conditions. Currently, Sand is scheduled to be surveyed and mapped for invasive species during the early-June time frame. Within one week of the mapping (weather permitting), herbicide will be used to treat areas that are found to have invasive plants. Any required swimming restrictions will be posted via paper bulletins along the affected shore lines. Additional surveys will occur after the treatment (to visually measure the effectiveness of the treatment) and in late July (to determine if a secondary treatment is advisable). Spot treatment of shorelines and canals will be treated in early june to prevent the spread of invasive species through prop strikes. Please bookmark this page for future reference.


Sand Lake is treating Eurasian Water Milfoil using the herbicide Renovate from SePRO.  You can read the Material Data Safety Sheet (MDS) here: renovateotf_msds
