  1. True. Water travels from Lake Simcoe north, into Lake Couchiching and then into Lake Huron's Georgian Bay.
  2. True. Weeds, or as we prefer to call them, aquatic plants, help protect the shoreline from erosion by slowing the action of waves that erode the shoreline.
  3. True. Invasive species is one of the top three concerns for Lake Simcoe along with climate change and phosphorus.
  4. True. Lake Simcoe has 18 major river systems, (Barrie Creeks, Lovers Creek, Hewitt's Creek, Innisfil Creeks, West Holland, East Holland, Maskinonge River, Georgina Creeks, Black River, Pefferlaw River, Beaver River, Whites Creek, Talb​ot River, Ramara Creeks, Oro Creeks North, Hawkestone Creek, Oro Creeks South, Uxbridge Brook).
  5. False. The earliest known name for Lake Simcoe was “Ouentironk (pronounced oo-ent-er-onk) which is the Huron word meaning “beautiful water". Early European settlers called it Lake Toronto. In 1793, John Graves Simcoe, the first Lieutenant-Governor of Upper Canada, renamed it Lake Simcoe, in memory of his father, Captain John Simcoe of the Royal Navy.
  6. False. Because Lake Simcoe is part of a much larger system known as the Trent-Severn waterway, its water levels are managed by Parks Canada.
  7. True. Lake Simcoe's water is the clearest it's been in years. We attribute this to the invasion of zebra and quagga mussels. These mussels have incredible filtering capacity; they can filter a volume equivalent to that of Lake Simcoe every five days!
  8. True. The amount of phosphorus in the lake is associated with the amount of runoff entering the lake. Climate change means more intense rainstorms; more intense rain storms mean more runoff; therefore more runoff means more phosphorus entering the lake.
  9. True. Not all blue green algae are harmful, BUT when blue green algae does produce harmful toxins, it's not easy to tell without sophisticated monitoring equipment. It's always safest to presume the toxin is present. If you suspect a algal bloom, stay out of the water and keep your pets out too. Report the bloom by calling 1-866-MOETIPS (663-8477) or TTY: 1-855-889-5775
  10. False. In fact, pulling up weeds from the lake bottom is illegal. Those weeds are fish habitat. You could also be making things worse by releasing tiny particles of invasive plants that can re-establish new colonies.
  11. True (mostly). Given the particularly sensitive nature of shorelines (lake, rivers, steams, etc.) it's most likely you'll need a permit if you want to do any work along your shoreline. You may also need permits from other agencies. By reaching out to us before making any plans, we can help advise you as to what is permitted. And if your plans don't require a permit, we'll let you know that too.
  12. True. Eventually all water that falls on the ground and then enters the rivers and streams in the watershed eventually makes its way to Lake Simcoe. That includes a number of towns that don't actually border the lake, like Newmarket, as an example. Our watershed is 3,400 square kilometers and includes 20 municipal borders, from the Oak Ridges Moraine in the south to the Oro Moraine in the north, through York and Durham regions, Simcoe County and the cities of Kawartha Lakes, Barrie and Orillia.
