    For the record, the KLRA has spent countless hours in communication with the District over the past 2.5 years to delay the removal of the bins and to find a better solution to our waste collection options for water access cottagers.

    Sadly, even with the real threat of losing them, the bins continued to be abused with illegal dumping. No matter who the culprits are, this has ruined it for the rest of our community. We feel the collective pain of the loss of the bins that is being discussed on our website and social media. Many of our board members are water access cottagers who understand the major, logistical challenge this will create this summer.

    HOWEVER, please know that your Board has not given up finding the best solution possible. We cannot stop what has been mandated by the Ministry of the Environment but we can continue to let our concerns be known to our local and provincial representatives. We will be closely monitoring the Sunday drop off day and will provide regular feedback to the District.

    We encourage all those affected to contact the District directly. In addition, you can comment on the KLRA's Facebook, Twitter or website pages which will provide an on-line dialogue over the course of the next few months.

    We will have a representative from the District at our annual AGM planned for Sat June 25th 10-12pm at the Gravenhurst Opera House. This will provide an excellent forum for our members to speak their minds and to be heard.

    As noted earlier, the MECP was notified of a small remaining algal bloom in the east end of the lake on November 12 and they carried out an investigation today. I've been notified that the bloom was no longer present and as such, no sampling was conducted.

    Unless there are further developments, this concludes the algal bloom alert for 2021.

    On November 2, the Ontario Ministry of Environment, Conservation and Parks (MECP) returned to the site on Sam Cook Road that was confirmed as a Blue-Green Algal Bloom in early October and collected another sample to determine if toxins (microsystin) were still present in the water. The laboratory analysis of the sample failed to detect any toxins, and as such the MECP notified the Simcoe Muskoka Health Unit (SMHU) and they in turn changed the health Alert status from Active to Resolved on November 10.

    However, I have been informed that an algal bloom still exists in at least one area at the end of the lake, and the MECP have been notified and asked for clarification regarding the status of the alert in areas where the bloom still remains. I will keep you informed when I hear more from the MECP.

    I have just spoken to the staff member at the Ministry of Environment, Conservation and Parks (MECP) who did the water sampling of Kahshe Lake last week regarding the blue-green algal bloom that was documented in the East end of the lake. She has clarified a number questions I had as noted below:

    • When she investigated two of the reported algal blooms on October 4th, there wasn't any algal growth present, so she submitted a sample collected by the property owner for analysis at the MECP lab.
    • She received the results confirming the blue-green algal bloom and passed them on to the Simcoe-Muskoka Health Unit (SMHU), and they issued the Health Alert for the ENTIRE lake, as there had been a number of other reports of algal bloom development over the past couple of weeks.
    • She agreed to my request for more information and will send me the lab report with the algal species that were identified as well as the toxin analysis results.
    • She also said that she won't be re-sampling the lake for another 3-4 weeks, as the bulk of the toxins are typically released as the algae start decomposing.
    • As soon as the results from the resampling in November are in and show no evidence of toxins, the SMHU will be advised and they will remove the Alert from their website.
    • I'll keep you posted as I hear more, but for now, the health advice applies to the entire lake if a bloom is visible in the vicinity of your waterfront.
    • And I've now received the actual alert issued by the SMHU and it as well as some warning signs that need to be followed have been posted below.

    cautioned about blue-green algae bloom

    Town of Gravenhurst - Residents and visitors to Kahshe Lake in the Town of Gravenhurst are being cautioned about a confirmed blue-green algae bloom impacting the lake.  

    The Simcoe Muskoka District Health Unit is asking residents and visitors to exercise caution where blue-green algae is visible and to take the following precautions:

    §  Do not use the lake water for the preparation of infant formula

    §  Do not allow pets or livestock to drink or swim in the water where an algae bloom is visible

    §  Be cautious about eating fish caught in water where blue-green algae blooms occur

    §  Do not use herbicides, copper sulphate or other algaecides that may break open algae cells and release toxins into the water

    §  Avoid swimming and other water sport activities where an algae bloom is visible.

    Blooms may make the water look bluish-green, or like green pea soup or turquoise paint.

    Many species of blue-green algae (also called cyanobacteria) have the potential to produce toxins that are harmful to the health of humans and animals. The Ministry of Environment, Conservation and Parks will be further analyzing samples to determine the presence of any toxins.

    Symptoms from consuming toxins from a blue-green algae bloom can include headaches, fever, diarrhea, abdominal pain, nausea and vomiting, and can be more serious if water is swallowed in large quantities.

    The health unit and the Ministry of Environment, Conservation and Parks will continue to work together to monitor the algal bloom and updates will be provided on our website ( as we receive new information.

    To learn more about blue-green algae visit the health unit website at, or call Health Connection weekdays from 8:30 a.m. to 4:30 p.m. at 705-721-7520 or 1-877-721-7520.

    One of several property owners on Kahshe Lake who reported the presence of an algal bloom earlier this week has just received confirmation from the Ministry of Environment, Conservation and Parks (MECP) that the bloom was a Blue-Green (Cyanobacteria) bloom. The Ministry has notified the Simcoe-Muskoka Health Unit and an Active Alert has now been posted on their website (link below): (

    I have been in touch with the MECP and although the level of specific toxins typically associated with this type of algal bloom has not been quantified, the Duty Officer did confirm that there was evidence of elevated levels. 

    I will keep you posted when I have more information, but for now, it's best to avoid contact with or consumption of the water by humans and pets in the vicinity of any blooms that are showing up. For more specific health related information, please refer to the SMHU like above.

    The next step in the District Municipality of Muskoka’s Causation Study for Bass Lake has now been released and is posted below. The material contains a link to the Terms of Reference which provide details on how the consultants are going to conduct the study and on the timing of the next steps to complete the work.

    Ron Pearson, Kahshe and Bass Lake Steward

    Thank you to everyone who has participated in the engagement and consultation opportunities offered as part of this causation study so far. The input and information you have provided has been valuable and has helped inform the development of the study’s Terms of Reference (TOR). The TOR has now been finalized and is posted to the Bass Lake project page at the following link: Bass Lake Terms of Reference

    Next Steps in the Study:

    • Data collection and field work will continue into the fall, after which the consultant will analyze the data to inform the study results and prepare recommendations.
    • A stakeholder meeting will be scheduled where the study findings and recommendations will be presented, and you can ask questions and provide feedback, which will be considered in the final report.
    • The timing of the stakeholder meeting may be affected by late fall blooms but is expected to take place in early 2022.
    • After the stakeholder meeting, the final report will be prepared and presented to the District’s Community and Planning Services Committee.

    A friendly reminder to continue to keep your eyes on the lake over the summer and fall seasons and report any sightings of potential blue-green algae blooms to the Ministry of the Environment, Conservation, and Parks’ Spills Action Centre at 1-866-663-8477.

    A number of people on Kahshe have been noticing or feeling little jelly-like little things in the water while swimming over the past couple of weeks. To solve the mystery of what they are, I collected a sample late on August 28 and have determined that they are a planktonic (water-borne) cladoceran identified as Holopedium glacialis. These little critters with their jelly-like sack thrive under conditions of low lake water calcium. I've reported on the trend towards increased numbers of them due to declining calcium concentrations in several of my Lake Steward Reports, as they have been documented as increasing in soft water lakes in Muskoka and neighbouring areas over the past few years. However, I had never actually encountered them in the water on Kahshe until this year..

    Briefly, what appears to be happening is that another cladoceran called Daphnia (another water flea) is slowly losing out to the Holopedium species, as Daphnia require much more calcium and phosphorus, both of which (especially calcium) have been in decline due to reduced leaching from soil since the abatement of the acid rain problem. I've done some initial research in the time since I discovered what they are, and the only negative impact I can find is a tendency of these jelly-like critters which are about 5mm in size to clog up water intake lines. I have not heard of this happening on Kahshe, but it can't be ruled out if they continue to increase in numbers. I'll be looking more closely at the research that has been conducted on them and will have more information to present in the next KLRA Krier or sooner if possible.
