Aquatic Invasive Species Info & Approved Lake Shore Providers

Our L.A. has worked with various government units to fund paid lake access inspections at 11th Crow Wing.   The inspections are aimed at increasing awareness, as well as focused on keeping our lake safe from AIS.  The following contributions were made in 2014: 10th/11th Lake Association $1000, City of Akeley $500, and Akeley Township $750. This was an increase by $500 from 2013, the first year of inspections. The results of the 2014 inspections are shown below for both 11th CW and summed data from Hubbard County. Note that 2 boats with Zebra Mussels were prevented from entering local Hubbard County lakes just last year, because of boat access inspections. Boater education is the key. Please remain vigilant.

Below are some links to Aquatic Invasive Species info.  This remains a very HOT topic in Mn, as the protection of our water resources are at stake.   Recently zebra mussel larvae were found in Lake Winnibigoshish (to the North East) and in various lakes in Douglas county.  Zebra Mussels are in the major rivers in Minnesota, along with lake Mille Lacs, Lake Minnetonka, Lake Superior, and certain Detroit Lakes and Alexandria lakes.  There are few, if any, effective treatments for these invasives.  Once they invade a lake, they are there for life!  We all need to do our part to keep them out of our lake.


One of the easiest ways for AIS (milfoil, zebra mussels, etc) to spread is with the transportation of docks and lifts.   Note: Per the first DNR link above, if you buy a used boat lift OR dock from another body of water, it MUST remain dry out of the water for 21 days minimum.  This is to limit the spread of aquatic invasives.

The businesses that provide boat lift and dock services need to understand how their practices can impact our lakes.  The companies listed below are aware of the AIS issues, have undertaken specialized training, and are compliant to the DNR rules. 

The first link is the full DNR list of approved providers.  The second link is for a more regional listing of approved providers from COLA.  We are in the process of compiling a list of approved companies that have been used by lake owners on 10/11th Crow Wing lake properties.  If you have a company to recommend, please bring to the fall meeting or send info to website admin .

What can you do to help preserve our lake and limit the spread of invasives?  Quite a bit actually!  We are all responsible for checking our boats for weeds and other aquatic invasives.  If you have visiting family or guests with watercraft, ask them where their boats have been recently.  Acquaint yourself with which bodies of water have invasive species.  Make sure the boat and trailer are: A) clean and free of weeds, B) have completely dry livewells and boat floors, and C) follow the DNR recommendations for being dry out of the water for a minimum amount of time (especially if in infested waters, see top link on this page for guidelines = 5 days is typical). 

Below are some pictures of what we are trying to avoid in 10th/11th Crow Wing Lakes:
