Cocolalla Lake Treatment Scheduled for Tuesday this coming week

A portion of Cocolalla Lake will be treated with Diquat for Eurasian Milfoil Control this coming Tuesday.  There is a 24 hour precaution for swimming within the treatment area, a three day restriction from drawing water for potable use or irrigation.  This treatment will not impact the majority of landowners on the lake, it is primarily focused on the southern portion.  Signs will be posted the day prior to treatment on the docks or your shoreline if you are in the treatment area.  You can also look at this map Treatment Map Link to view the location in relationship to your property.  You can also call 360-201-2612 to ask questions of our team.  The Idaho State Department of Agriculture staff contact is Nic Zurfluh at 208-631-9574.
