2020 Eurasian Watermilfoil Survey Report

Current conditions of Round Lakes invasive species 

Our goal continues to be focused on controlling existing aquatic invasive species to minimize navigation impairment.  Purple loosestrife was observed in 2014 in Little Round Lake, but not documented during the 2020 surveys in either lake.  Flowering rush was found at one location in southern Musky Bay of Round Lake in 2019 & 2020 but is mixed with native emergent vegetation and not cause for concern.  


Eurasian watermilfoil continues to be the main concern in Round Lake.  The RLPOA realizes that, unfortunately, complete eradication of EWM is not a realistic goal.  Chemical treatment has had success since EWM was discovered in Round Lake in 1993 and first treated in 1994 and has proven to be the most effective treatment in controlling the spread of EWM as well as the most economical option (the most expensive chemical treatment year for Round Lakes was $32,600 in 2019, a significant portion used to successfully treat Richardson Bay. The largest non-chemical treatment was DASH in 2018 at a cost of 41,200). 


Based on 2020 EWM survey results, the following beds will be targeted for herbicide treatment in 2021. A20, B20, C20, D20, & S19 located in or near Blue Island Bay (Map 8) . G20 located in Fisherman's Bay (Map 3).  U20 & T20 along the southwest shore of the large peninsula (Map 5).  X20 in Richardson's Bay (Map 4).

It is our hope, that with ongoing rigorous surveying to guide herbicide treatment, the occurrence of EWM will remain low in Round Lake with greater manageability and more cost-effectiveness in keeping the EWM at low levels.


Seeking One Year DNR Grant to Fund Education, Surveys and EWM Treatment

We have applied for a one-year grant from the DNR to assist with funding for next year’s AIS activities. This project will allow continued surveying of EWM in Round and Little Round Lakes.  Such work is necessary to better understand effective EWM control techniques in these lakes.  For example, DASH was used to control EWM in 2017 and 2018.  The RLPOA was eager to have this method of EWM control available at that time.  Lake residents, especially in Hinton Bay, became concerned that DASH caused increased occurrence of EWM in 2017-2019.  Lake residents observed fragmentation of EWM caused by DASH even though volunteers were netting fragmented EWM from their kayaks.  There remains strong opposition to DASH in Hinton Bay because residents observed significant EWM increase after DASH was employed, ultimately leading property owners and the RLPOA to conclude that DASH made EWM "worse". As a result, DASH was not used in 2019 or 2020 and herbicide was used in its place. 


RLPOA also understands that with rapid herbicide dissipation in small-scale treatments, there is concern over effectiveness of this method. However, RLPOA believes this to be the most effective means of keeping EWM managed and at non-impairment levels. That is way our grant proposal includes another year of surveying to delineate new EWM beds and take rake samples at 500 points at old and new beds managed in some way since 2018.  Furthermore, the RLPOA is interested in the use of ProcellaCOR (PCOR) and would like to closely track efficacy and impacts to native species.  A PCOR treatment trial at 1.25 ac 8' deep in 2020 at the northeast corner in Hinton Bay. This project is unique and necessary because it allows for continued rigorous surveys of areas that have been treated since 2018 as well as ongoing control. We continue to subscribe to the practice of 

integrated pest management (IPM) principles which employs information about EWM's life cycle and its negative effects in combination with available control methods to determine the most economical means with minimal hazard to people, property, and environment. 



The Round Lake Property Owners Association (RLPOA) is applying for a permit from the Wisconsin Department of Natural Resources to treat approximately 20 acres of Round Lakes with an aquatic herbicide to control the invasive plant Eurasian Water Milfoil. This proposed treatment would occur between June 1 and June 30, 2020.


The RLPOA will conduct a public information meeting on the proposed treatment if five or more individuals, organizations, special units of government, or local units of government request one. The meeting would give citizens a chance to learn more about the proposed treatment from the permit applicant. The RLPOA is not required to but may change the proposed treatment based on information provided by citizens who attend the meeting.


Any request for a public meeting on the proposed treatment must be made within five days after this notice is published. The request must specify the topic to be discussed at the meeting, including problems and alternatives. The citizen or organization requesting a public information meeting must also provide a current email address and phone number in case a meeting forum would need to take place online do to the current COVID-19 restrictions. The request must be sent in writing to the RLPOA, PO Box 1070, Hayward, WI 54843 and the Department of Natural Resources, 801 W Maple Street, Spooner, WI 54801.


This notice is required by Chapter NR 107.04 (3), Wisconsin Administration Code.

AIS Update - Treatment Plan Revised

There have been significant milestones this year in the RLPOA effort to control Eurasian water milfoil (EWM) in Round and Little Round Lakes.  The first is more member support.  Dave Rutt and Jim Nancekivell, Round Lake property owners, where voted onto the board of directors at the July annual meeting.  They are co-chairs of the aquatic invasive species (AIS) committee and will lead association AIS treatment activities.  Other milestones were the successful treatment of Richardson Bay and the not so successful treatment of Hinton Bay.

In June, NEC, Inc. performed a whole bay chemical treatment of Richardson Bay.  This was the culmination of a 6-month planning and permitting process that involved the WDNR, LCO Conservation Department, and outside consultants.  Post treatment visual surveys indicate a stunningly dramatic reduction of milfoil in the bay.  We will continue to monitor the bay to gauge the long term effectiveness of the treatment. We are very pleased with the results so far.

In late June, members of the board and aquatic plant specialist Sara Hatleli toured Hinton Bay to assess the extent of milfoil in the bay.  For the past two summers, the association used diver assisted suction harvesting (DASH), a non-chemical treatment method, for milfoil control in the bay. During the tour, it was apparent that there was significant expansion of milfoil along the east and south shores and new locations identified on the west shore. Based on what was observed, the consensus of the group was that DASH treatment was not effective.  Armed with this information, the board voted to cancel all DASH treatments scheduled for 2019.

Property owner Dave Rutt, initiated a Go-Fund-Me campaign to raise funds for chemical treatment of Hinton Bay. With the generous response from Hinton Bay residents, $16,237 has been raised to date for treatment of the bay.

Dave and the RLPOA worked with the DNR to develop an alternative 2019 treatment plan for the bay.  After extensive consultation with the DNR, a plan was approved to spot treat two acres of milfoil that were navigational nuisance areas in the bay.  We were disappointed in this outcome, but it was the best that could be done on short notice.

The DNR does recognize that there is a significant milfoil issue in the bay that needs to be addressed.  The RLPOA is working with the DNR, LCO, and consultants to develop a whole bay treatment plan to be executed in 2020. The Go Fund Me dollars that Dave raised will be instrumental in the fulfillment of the plan.

In August, Aquatic Plant and Habitat Services, LLC. performed a survey of several known milfoil locations in Round Lake.  Its purpose was to document the size and density of milfoil at each location. This data is important because it will be used to plan future milfoil treatment activities. 

We would like to thank everyone who has contributed so generously to the aquatic invasive species fund this year.  Please encourage your neighbors to join the RLPOA and support the efforts to maintain and enhance Round and Little Round Lakes. We also want to remind everyone to avoid the use of fertilizers on your lawn— a healthy lake is far more important to your home’s value than a weed less lawn.

DASH Milfoil Removal Announcement
The RLPOA has contracted with TSB Lakeshore Restoration and Diving to perform two weeks of diver assisted suction harvesting (DASH) of Eurasian water milfoil throughout Round and Little Round lake. This is a non-chemical method to remove milfoil from the lakes. Work will commence on Monday July 30 and finish August 10. No work will be done on Saturday or Sunday.

Please stay at least 200 feet away from the work barge and divers to assure their safety.

A map of the proposed DASH removal locations is available above.
