It has been a busy summer and it is good to see things slowing down as we move into the fall. Many watercraft inspection stations are now closed. Other stations on high risk corridors will remain open through October. Crews are still surveying for AIS, but they will be wrapping up as water temperatures cool. To date, no evidence of invasive mussels has been detected this season. Great news. But small populations can be easy to miss and it is important to remain vigilant. Read the AIS Newsletter.
