Historic Lake Levels and Surveys

Source: Ontario Ministry of the Environment – 1978

  • The regulated lake level was established in the early 1950s by the Department of Lands and Forests.

  • Reviewed and maintained in 1960s by the Department of Lands and Forests.

  • Altered in 1978 and again in 1981 by CVCA in cooperation with MNR.

  • Lake bottom mapped in 1961 by CVCA. Lake was surveyed by MNR in 1973, and updated in 1979.

  • The CVCA monitors the lake level of Lake Kasshabog. There is an automated gauge at the east end of the lake that keeps CVCA up to date on the water level. Residents can check water level readings anytime by visiting  


  • The land surrounding the lake is typical of the Precambrian Shield, with bare rock ridges and shallow till. Much of the surrounding area has low wet areas, with organic bottom deposits.
