Managing Aquatic Invasive Species is a primary function of the association. We work closely with the DNR and Crow Wing County to minimize the spread of AIS into our lake. We monitor the efforts of the Minnesota Aquatic Invasive Species Center and other groups that are developing approaches to eliminate AIS. Crow Wing County has a 2021 AIS Plan that includes North Long.
At this point in time, it's a combination of remediation and prevention. We're able to control Curly Leaf Pondweed near the Merrifield Bay access. But there's no proven remedy yet for Zebra Mussels.
Our I-Lids cameras at the Merrifield and 371 Bay access points are our primary tool for prevention. These cameras operate 24/7 and are an effective reminder - with the possibility of enforcement action by the DNR - to check boats and trailers before entering the lake.
The association is tracking the spread of zebra mussels in North Long. If you spot a zebra mussel on your dock, lift, or shoreline, please report it - including your approximate location.
Curly Leaf Pondweed
Curly Leaf Pondweed is an aquatic invasive plant species that causes problems by creating extensive mats in 3-10 feet of water. In North Long, it primarily affects an area in the northeast corner of Merrifield Bay. The association treats this area with an herbicide annually; in 2016, approximately 7 acres were treated.

Transporting Equipment with AIS
Owners of equipment such as boat lifts, docks or swim rafts transporting their equipment with prohibited invasive species attached require a permit.
Lake Service Providers
Lake service providers (such as dock install/removal) should have training and permits from the DNR. A list of permitted lake service providers can be found here.
