Everyone knows about Nessie, the lake monster of legend purported to inhabit Loch Ness, a lake in Scotland with a topography similar to Loughborough Lake. Over the many decades of sightings, various explanations have been put forth regarding the origin of this mysterious lake monster. The most popular, no doubt, is that Nessie is one of the last remaining Plesiosaurus, a lake dinosaur that was presumed extinct over 66 million years ago.
In August 2017, over a period of nine days, MNRF’s Science and Research branch conducted the first ever Broad-Scale Netting program on the lake. The results were shared with you in the fall 2017 newsletter. Analysis of zooplankton in the lake took longer and Joel Clarke, a technician with MNRF, recently sent the results.
Since 2015, the Lake Association has actively partnered with the Ministry of Natural Resources and Forestry (MNRF) to assist with stocking the west basin with Manitou Lake Trout fingerlings provided by the White Fish Lake Culture Station. This endeavor has grown in scope to allow 15,000 trout to be released in under two hours for each of the past two years. In addition, two boats, full of students from the Queen’s University Biology Department, have joined us. This year’s stocking event, which was held on May 17 th in beautiful sunny conditions, concluded with MNRF providing a barbeque lunch for all of the volunteers.
No doubt you have viewed a Google Earth image of the lake and wondered: Why is it long, narrow and oriented NE-SW? Why does the NE part of the lake have islands and the SW part does not? When did the lake valley form and by what processes? The modern land surface here is related to periods of glaciation that ended about 11,500 years ago. Before that time glacial ice sheets ~ 2 km thick advanced over the area from the NE to the SW and eroded the bedrock surface. However, this alone does not account for all the surface features found in the region.
The Eastern Ontario Model Forest (EOMF) and Pinegrove Productions have produced a new documentary video series that celebrates stewardship of Ontario’s natural heritage in forestry. “Trees, Youth, Our Future” is a two-part series that tells the story of forest stewardship in Ontario and encourages the next generation of leaders to embrace it.
One of our most compelling summer visitors keeps itself aloft in air that, to it, must feel more like maple syrup. The reason this bird does not soar through the air like a Bald Eagle is because it is, well, very, very small. It is in fact one of the smallest birds in North-America: I am speaking of course of the Ruby-throated Hummingbird.
Our next-door neighbouring lake, Dog Lake, had another toxic blue-green algae bloom in 2018. This “infection” shows up as a scummy surface growth and, due to its toxicity, makes the lake water unsuitable for drinking, swimming, bathing, and eating fish - basically everything water related that you enjoy at the lake. Blue- green algae cannot be filtered out of the water with cottage or home filter systems. Boiling the water can increase its toxicity.
