[English] Lake Temiskaming, a freshwater lake is shared by both Ontario and Quebec as it forms part of the provincial border between the two provinces. Created during the last ice age, as the glacier carved its way through the rock, the lake is what remains of the original Lake Barlow-Ojibwa, which existed over 10,000 years ago. The waters of the lake are deep and who knows what could be swimming beneath its waters! The names given to the creature of Lake Temiskaming are “Mugwamp”, “Mudwump” or “Tess”. Some attribute the strange occurrences to that of a large sturgeon or a creature that is long and shaped like a dinosaur. Keep your eyes open!

[Français] Le lac Témiscamingue est un lac d'eau douce qui se partage entre les provinces de l'Ontario et du Québec en servant de frontière interprovinciale. Formé au cours de la dernière glaciation alors que les glaciers se frayaient un passage dans le roc, le lac est le vestige de l'ancien lac Barlow-Ojibwa d'il y a 10 000 ans. Les eaux du lac sont profondes, et qui sait ce qui nage au fond! Le nom donné à cette créature du lac Témiscamingue est « Mugwamp », « Mudwump » ou « Tess ». Certains interprètent ce phénomène par la présence d'un énorme esturgeon ou une créature de même dimension et apparence qu'un dinosaure. Nous vous conseillons de bien ouvrir l'œil!

Excerpt: Lake Ojibway was a prehistoric lake in what is now northern Ontario and Quebec in Canada. Ojibway was the last of the great proglacial lakes of the last ice age. The proglacial lake was named Ojibway in 1909 by Canadian geologist Arthur Philemon Coleman after an Indigenous people whose homeland coincides with his proposed location of the lake. Comparable in size to Lake Agassiz (to which it was likely linked), and north of the Great

Lakes, it was at its greatest extent c. 8,500 years BP. The former lakebed forms the modern Clay Belt, an area of fertile land.
Lake Ojibway was relatively short-lived. The lake likely drained approximately 8,200 years BP. One hypothesis is that a weakening ice dam separating it from Hudson Bay broke, as the lake was roughly 820 ft above sea level but recent studies assert Lake Ojibway drained in two separate events and through a combination of ice dam breach and subglacial flooding.
