CHARRON LAKE

CHARRON LAKE

  • Type: Simple
  • Diameter: >4.5 Km (at its widest point)
  • Location: Eastern Manitoba, Canada N 52° 44’ W 95° 15’

A strongly negative magnetic anomaly coincides with Charron Lake, Manitoba. D. H. Hall (University of Manitoba) calculated that the removal of a block of the slightly magnetic country rock granite would produce the negative anomaly over the lake.
The Charron Lake caldera has a roughly square shape.
The north and south sides of the lake are relatively smooth as they are controlled by ancient Precambrian fractures. The east and west sides of the lake have a rough, torn appearance with short irregular fractures making sharply defined bays in the fracture pattern of the ancient surface. The pattern is typical of an explosion. The shape of the structure is illustrated in this image, taken from an altitude of approximately 2000 feet above ground level. The water in the lake is clear and very deep in terms of hundreds of feet.

CHARRON LAKE

Charron Lake is roughly a circular lake fed and drained by the Palsen River which drains north to the arctic. Terrain is rolling and moderate, typical of the western Precambrian shield. Some suggestion that the lake is a meteor impact crater may be supported by the angular rocks observed underwater mainly in the SW quadrant. The lake has over 100 islands and in places has a rugged and jagged edge. Low spruce populate any areas when soil has accumulated. Alders edge into the lake. There is little organic debris entering the lake. Water is not tannic and fishing is excellent for walleye, lake trout and northern pike. There are no roads anywhere near the lake. The lake was fished and trapped by native people but by in large there are no regular inhabitants on the lake. Caribou, bald eagles, vultures, bears, beavers and the occasional pelican make up the fauna in the area.

Lake Charron, top centre, contains a very strong magnetic anomaly (Natural Resources Canada).
