2015 Treatment Report

Kristy Maki passed the milfoil baton to Pat Brown, who approved the treatment of six acres with Max-G herbicide on June 26.
Most of the milfoil was concentrated in the NW and NE corners of the lake.  June 26 is 2 to 3 weeks later than normal.

2014 Treatment Report

Kristy Maki produced a report that showed the success of last year's treatment
and requested a grant extension for 2015, when another treatment will be needed
on the north end of the lake.  Renovate Max-G appears to be effective in the battle against milfoil.

2008 Treatment Report

PJ,

I treated 5 acres of EWM [Eurasian Water Milfoil] on Osprey yesterday.  
I think the timing was right.  The EWM that I could see was actively growing 
and the "natives" were just getting started.  The water was a bit cloudy 
which made it hard to see the plants.  
I billed Dale Olsen at the county like last year and I am attaching 
the Herbicide Treatment Record and some GPS info for your records. 

Let me know if you have any questions.   Thanks for your business!

Hi PJ,

If you aren’t up here today, you missed a beautiful day at the lake! I finally got out on Osprey Lake today. I had very calm weather and got to see all of the “hot spots” for EWM. I checked out all of your buoys and picked them up, hope that is alright. I’ll have them here if you want them back. I found only one EWM plant in the north bay. Most of what you had marked was northern milfoil. I found a few spots by the island, and then more over by the inlet. We should definitely plan on treating the shoreline near the inlet (all along the wetland area there) and then on the east and west ends of the island. I don’t think it looks bad out there at all, though. I think the treatment this spring was very successful and you are on your way of keeping it under control. Let me know if you have any questions. When I get a chance, I’ll download all of the points I took today and get you a map with approximate acreage for treatment.

Hope you’re having a good fall.

Kristy

Kristy

I would like to send a Fall follow-up letter to all who contributed to our fund raising effort. Do you have some sort of summary report showing the results of the treatment we did last spring?

Thanks

PJ

Hi PJ,

I’ve attached a map showing the latest Eurasian water milfoil survey that I did. I would estimate that around 3 acres of scattered milfoil is in the lake right now. That is a good improvement from 8 acres this spring before the treatment. I think the 2006 treatment was very successful and a much smaller treatment will be needed in 2007.

The lake was surveyed 3 times this summer for Eurasian water milfoil and other plants. The WI DNR performed an aquatic plant survey and found only a few areas of milfoil. I performed 2 surveys specifically for EWM. The July survey showed only a few EWM plants near the inlet, meaning there was good control from the June treatment. In the October survey, more EWM was found, but that was not a surprising find. As the summer goes on the plants that did survive the treatment begin to grow again and are more easily observed in the fall. Another treatment should be done as soon as the plants begin growing in the spring. It is still important for the lake association to continue to monitor the location of the EWM plants and be careful to avoid boating through infested areas in order to not spread fragments to other areas on the lake. The lake association should be prepared to fund another treatment in the spring. A spring survey will have to be done in order to determine the exact acreage that needs to be treated, but the treatment area will most likely be reduced by about 50% from last year. Hopefully that trend will continue until you are just treating small spot areas.

Hope this information helps. Let me know if you have any questions.

Kristy
