Milfoil Monitors

Volunteer Training

  • Thursday, July 6, 2017
  • 8:30 a.m. to 10:30 a.m.
  • Squash Lake Boat Landing (Gudis Landing) on Long Lake Road

The Squash Lake Association will conduct Eurasian Water Milfoil Monitoring and Safe Removal training for volunteers.  The training will be led by Stephanie Boismenue from Oneida County Land and Water Conservation as part of our DNR Education, Prevention, and Planning and Aquatic Invasive Species Control grants.  The two hour training session will cover proper identification of Eurasian Water Milfoil and other aquatic invasive species, proper and safe removal techniques in shallow water, and a field trip on the lake to identify EWM from a boat.  The event is rain or shin, except heavy downpour or lightning.

Regardless of the status between the lake association and the new lake district, the time you spend in the training session and in being a Volunteer Milfoil Monitor count towards the local share obligation of our grants.  Our volunteer hours are necessary to get a full reimbursement on our grant expenses.  learning how to identify EWM also helps our divers focus on problem areas around the lake and makes EWM diver harvesting more efficient.

New EWM Monitoring and Removal forms for tracking volunteer work as a Volunteer Milfoil Monitor will be available.  They will replace the older forms we have been using.

I look forward to seeing you there.  Please let me know if you plan to attend so we can plan accordingly.  You can contact me at: or 608-628-5151 to sign up.

We could not have accomplished so much or been as successful without our volunteers.  Thank you.

Dear Volunteer Milfoil Monitors,
Thank you everyone for volunteering to be a Milfoil Monitor. Your interest & ongoing volunteer effort will help protect the lake’s ecological integrity.  As a Volunteer Milfoil Monitor, you are contributing to the success of Squash Lake Eurasian Water Milfoil Control Project Grant.   Thank you so much. I really appreciate You!

Here are a few quick reminders and clarifications:
Attached are the forms needed: SLA 2015 Volunteer Milfoil Monitors Report Form, SLA Map with Grid for VMM and Milfoil picture sheets. Please use these forms each time you monitor your area. If you are able to print these forms at home, please do so. Otherwise, there are some in the shed at the boat landing.

Please contact us if you can help monitor this year.  Your participation is another step toward lake preservation. Training and refresher classes are available.   Craig Zarley, 715-282-6554  or  Marj Mehring, 715-360-6573

Volunteer Milfoil Monitor Participation Description:
As a Volunteer Milfoil Monitor, please monitor your area (your own property, neighboring properties, and any other area that we may have discussed) for EWM and other Aquatic Invasive Species.

1). Search the littoral (shallow water) zone of your designated areas for fragments washed up on shore, floating fragments, new plant locations, and reoccurrences in previously harvested areas.

2).  Inspect, visually the lake bottom for Eurasian Water milfoil.  Slowly cruising the area, back & forth to a depth plants are visible -6 to 8 feet deep.  This can be done by whatever way is comfortable for you.  Suggested ways:   Standing in a boat, snorkeling, via canoe, kayak, Stand Up paddle board or paddle boat etc.

3).  Additionally, please mark plants and dispose of EWM fragments.  Mark the plants by dropping a marker approximately 1 foot from the plant.   Any float will do, just mark it “EWM, please do not remove”.   Attach an 8 to 10 foot string to the float & anchor it with whatever is handy.  I use a baseball sized rock in an old nylon stocking as the anchor.  EWM brakes apart easily so please do not try to pull a plant without equipment & training.

4).  Always record the time spent and the results each time you monitor.  Even the 5 to 10 minutes spent before or after boating will add up by the end of the summer.

Monitoring Frequency:
May – September.
Ideally, monitoring should take place several times a month. However, I realize that we are all very busy & nice summer days are few. Therefore monitor at least once a month. If you are unable to monitor for a certain time frame, ask a neighbor or other volunteer to help out. Otherwise, give me a call and I’ll help find coverage.

Recording Your Monitor Area ID’s on the Report Form:
If you are having trouble with identifying your monitoring areas on the map and I will be happy to help, just call.

Reporting EWM Sightings:
If you find any EWM fragments washed up on shore or floating please yank them out of the lake and dispose of them. Report new findings as soon as possible.  Call Marj or Craig.

For new rooted/established plants, please contact us ASAP to report your findings and we’ll get a diver there to remove it and record its location on the GPS.

The best way to reach us:  Craig 715-282-6554 or Marj 715-360-6573. If no one answers, please leave a message and your call will be return.

When and How to Turn In the Report Forms:
Please sign the bottom of the report form and return to me in July (midseason)& in September (end of season).  You can either:

  • Put them in the shed at the boat landing, place in the folder marked “Completed Volunteer Milfoil Monitor Report Forms”. There is also a folder that has blank forms.
  • Snail mail: Marj Mehring, 2853 Bay Dr, Rhinelander WI 54501
  • Place it in an envelope & leave it by my front door (stop by and say hi);
  • Chase me down if you see me out and about on the lake;

Scuba Divers:
The same scuba diving crew is back this year.  Tom Johansen is coordinating the divers & their schedules.  They will begin working early in June, depending on water temperature. If you see them out on our beloved Milfoil Terminator, give a wave and thumbs up or stop by their work area and ask how’s its going. If you do stop by the work areas please approach very slowly, cautiously, and with the motor off. Oh, I should mention that the guys are always appreciative of snacks, baked goods, and cold water or juice.

Please share this with your family and friends: If you see a red flag with the white diagonal stripe, that is a scuba divers “diver-down” flag. Scuba divers who are under the surface will have a “diver-down” flag at the surface. Please slow down. Per WI boating regulations: All vessels not engaged in scuba diving activity must stay 100 feet away from displayed diver-down flag.
