As part of the MLRA Lake Watch initiative, the MLRA added a “Water Safety Tips” section on the home page. Also as part of that same initiative we are going to continue to post articles and information about water safety on the MLRA website to help educate residents and visitors to the Lake about water safety.

Please make sure that you read the posting below thoroughly and pass the information along. Also please make sure that any visitors that you may have to the Lake are aware of WATER SAFETY. You may save a life!
A synopsis of what is happening in our lake, by Dr. Brian Laing.
So, why are we seeing more algae this Spring?
This winter has been long and hard and the spring late in coming. This has delayed the normal slow blooming of algae and had made it come all at once. Algae cells are able to rise into the warmer water at the surface of the lake and consequently take advantage of the sudden warming of the water. This has been one of the harshest winters in living memory so it stands to reason that it will have a transitory effect on the ecology of the lake.
Of greater concern are the trends in water quality in our lake. As detailed in Dr Hutchinson’s water quality study of the lake, the overall health of the lake is good, and improving.
As we have suspected, Dr Hutchinson determined that one of the major problems controlling algae blooms and plant growth is the internal loading of phosphorus. Phosphorus is the primary nutrient that controls growth of plants and algae in most lakes. When plants and algae die and decompose on the bottom they release phosphorus into the water. Under aerobic conditions (plenty of oxygen) the phosphorus is bound up and unusable for plant or algae growth but under anaerobic conditions (little or no oxygen) this phosphorus is released back into the water in usable form. This is called internal phosphorus loading an it is largely responsible for the algae blooms and plant growth. In the winter the bottom of the lake becomes particularly anoxic and results in extra phosphorus being available for algae and plant growth in the spring. This winter was harder than usual likely resulting in greater phosphorus being available. The other ingredient for algae growth is warm water. Because this was delayed this spring, when it did come there was plenty of phosphorus available for eager algae to use.
Past studies have shown that the phosphorus level in Musselman’s Lake have decreased by 50% between 1989 and 2006. Dr Hutchinson’s results show that it has reduced further in 2013. This is good news. Our lake’s total phosphorus concentration is below the Provincial Water Quality Objective ‘for protection against nuisance growth and algae, and would not be indicative of impaired water quality, particularly for a lake in Southern Ontario’. Because of this, Dr. Hutchinson has recommended that we not pursue phosphorus sediment inactivation techniques such as phospholock at this time. He did however recommend that we continue to monitor water quality to track the inter-annual variability and if the internal phosphorus loading is in an up trend then the community should consider phosphorus sediment inactivation techniques at that time.
So in conclusion, while the algae mats are unsightly, they do not mean that the health of our lake has suddenly a turn for the worse. Fortunately Geranium homes generously supported the detailed professional analysis of the Lake by Dr. Hutchinson which gives us a baseline of the lake’s water quality.
It is our belief that we as a community should organize and raise money for ongoing monitoring of the lake so that trends can be identified and informed decisions can be made on if and when remedial action is necessary. The monitoring also enables us to gauge the effects of the actions we institute.
Golder Associated Ltd. has completed baseline groundwater monitoring at the Lee Sand & Gravel property located at 14245 Ninth Line, Town of Whitchurch-Stouffville, Ontario (referred to as the “Site”) to determine the chemical quality of the on-Site groundwater. The baseline study conducted in 2012 consisted of installation of monitoring wells around the perimeter of the Site with additional monitoring wells in the central area of the Site. In August 2012, the reported concentration of phosphorus in these monitoring wells were less than the laboratory detection limit (<50 micrograms per Litre). In addition, based on groundwater elevation data and groundwater monitoring events completed between 2012 and 2014, groundwater has consistently been found to flow in a south-southwesterly direction (i.e., away from Musselman’s Lake).
Based on our current understanding and findings, it is unlikely that phosphorus levels in Musselman’s Lake (located approximately 900 m north-northwest of the Site) are affected by the activities at the Lee Sand & Gravel Site. We note that inorganic phosphorous in groundwater is typically present as orthophosphate, which is not particularly mobile in groundwater. Further, the Lake Simcoe Region Conservation Authority’s report on Musselman’s Lake identified runoff from agricultural land, urban stormwater runoff, and discharges from improperly functioning septic systems as significant contributors of phosphorus to the Lake .
Please keep an eye out for suspicious activity at the Lake. There have been several boats vandalized in the last 2 weeks. If you see anything unusual please call York Regional Police or if you have any information on the crimes and wish to remain anonymous you can also call Crime Stoppers

A cyclist was seriously injured after being struck from behind by a truck in a hit-and-run.
The 33-year-old man from Toronto was riding southbound on York-Durham Line when he was struck by a black truck, according to Durham police.
The man was rushed to a Toronto trauma centre where he remains in serious condition.
The suspect vehicle is described as an older black tow truck with dual wheels at the rear and “FREE TOW AND SCRAP” written in white lettering on the sides of the vehicle.
Durham police believe the black truck will have damage to the front end.
Anyone with new information regarding this investigation is asked to contact Durham Traffic Services Branch at 1-888-579-152, extension 5231.
Anonymous tips can be made to Crime Stoppers at 1-800-222-8477(TIPS) or on the website at www.durhamregionalcrimestoppers.ca.

The Results are in…The Lake Is Doing Fine!
The Geranium Corporation sponsored Water Quality and Management of Musselman’s Lake report has been completed by Dr. Neil Hutchinson of Hutchinson Environmental Sciences Ltd., and the findings are very positive.
Please take time to view both videos below as they are very enlightening. You will learn how both rooted plants (weeds) and algae play an integral part in the health of the Lake’s delicate ecology. The first video is a short summary and the second one is Dr. Neil Huthchinson’s full presentation on the Lake. Dr. Neil Hutchinson does such a great job of explaining how there is more to our Lovely Lake than meets the eye. It is a very complicated ecosystem that goes through some pretty amazing seasonal changes that most of us are unaware of. The full video is well worth taking the time to watch.

Brian Ginn, Liminologist, with The Lake Simcoe Region Conservation Authority has been in contact with MLRA President, Rick Wigmore to inform us the lab results are in from water samples taken back in May. Musselman’s Lake’s water chemistry test came back ” normal”. Our beautiful Musselman’s Lake continues to shine even under the microscope of extensive studies and testing.
As part of the LSRCA continued study of Musselman’s Lake they were back on the Lake this week and took additional water samples to help us further understand the complexities of the seasonal changes our Lake goes through. Brian Ginn will update us once he has these samples back from the lab.
Saturday April 25th was a great day here at the Lake and through your efforts and generosity we all made a positive, noticeable difference to our community and the environment.
Thank you all for your contributions and for dedicating your time and hard work to help make our Community Clean-up a success and a day to remember. We couldn’t have done it without you!
Tiny Seedlings for providing the fantastic catered meal that we all enjoyed.
United Soils for providing the garbage bins and garbage bags and staff to help clean up. United soils also graciously donated their sweeper to remove as much sand and debris left over from winter and keep it from washing into our precious lake.
George at the Coolest Little Ice Cream shop for all of his help.
Mike and Most Excellent Productions for doing all of the sound and keeping us entertained.
Cedar Beach Resort for providing a great location to host our event and all of the equipment and staff.
This year we collected a staggering amount of garbage out of the lake by our water teams and off the roads and ditches that surround our community. In total we removed 2 full bins totalling over 40 yards of garbage!
We also collected 10 great bikes that were donated that same day to Africycle and will be on their way to Africa making a huge difference to the children those bikes reach.
We collected 47lbs of used batteries that were taken to a recycling center and that we kept out of our landfill. The sweeper made great progress and removed tons, literally tons of material from our roads that will never wash into our lake.
Well done everyone! We have a lot to be proud of. Without the great support of all of you this event never would have happened, pat yourselves on the back!
Stay tuned to the website for important updates as we keep you informed on what is happening in our community.
We have been working with Tiny Seedlings and they have graciously offered to donate a fantastic lunch for everyone who helps out. This year it won’t be the usual, hot dogs. This year we get to warm up with homemade chili and corn on the cob! Thank you Tiny Seedlings!
United Soils has not only offered to supply the garbage bags and gloves that we needed but will also be supplying 2 garbage bins for all the waste we are going to collect.
One of our concerns for the Lake is water runoff and the sediment that it carries into the Lake. After a long winter there is a lot of sediment along the sides of the roads that needs to be picked up. When we presented this concern to United Soils they once again stepped up to help our community and offered to use their street sweeper to clean the areas of concern! The sooner we can get the gravel and sand off the road, the more of it we can keep out of our Lake!
We will be collecting used bikes for Africycle, if you have a used bike laying around please drop it off knowing that it is going for a great cause. There is more information about where these bikes go after you donate them at www.africycle.org.
Are you collecting used batteries but don’t know what to do with them…..bring them by and lets keep them out of the landfill, let us dispose of them for you!
If you have a boat that you can’t get out of the water or a dock that is garbage don’t leave it in the lake, email us and we will come by and help you remove it.
Cedar Beach Park will be providing large recycle bins for everything from metal to plastic, lets keep as much out of landfill as possible.
Can’t wait to see everyone Saturday morning, come early for coffee and we get to end with a great lunch and entertainment by Most Excellent Productions!
Should be a fantastic Day!!
Don’t forget, today, that is actually Earth Day please take time to think of our community and our environment and what YOU can do to make a difference.
