Lake Levels and Surveys

  • 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 surveyed by MNR in 1973, and updated in 1979.
  • The CVCA monitors the lake level of Lake Kasshabog via an electronic gauge located on the south side of Connor Bay (it’s the concrete and steel structure on the waters’ edge near the landing off FR-75 also known as South Connor Bay Road). Levels are recorded every 4 hours. There are also two staff gauges; one located at the west end of the dam, and the other at Stoney Point Marina.
  • The land surrounding the lake is typical of the Precambrian Shield, with bare rock ridges, and shallow till. Much of the surrounding area is pocked by low wet areas, with organic bottom deposits.

Lake Location, Development, Water Quality and the Environment

Source: Ontario Ministry of the Environment – 1978

Kasshabog Lake is located approximately 22 km north of Havelock in Methuen Township. The lake receives flow from several smaller tributary lakes. The major inflow is from the North River which is part of the Crowe Lake system (see separate flow sheet). Although the lake has many islands and bays, only MacDonald (Bill’s) Bay appeared to be hydrologically separated from the main lake. In 1978, the lake had 16 permanent residences, 504 cottages, and 4 cottage rental units. In addition, MacDonald Bay had 81 cottages along its shoreline. The volume of water in MacDonald Bay flushed itself about twice during the year, while the rest of the lake flushed only about once a year.

Kasshabog Lake had soft, slightly acidic water with a moderately low amount of apparent colour. The hardness, alkalinity, and conductivity levels indicated the lake was well mixed. Thermal stratification (temperature layers) were noted in almost all the bays and monitoring stations. Water clarity was moderately good throughout the lake, and the secchi disk results indicate the lake is mesotrophic, or moderately enriched.

Dissolved oxygen distribution throughout the lake showed a gradual decline with increasing depth, probably due to the decomposition of organic matter in the bottom waters. No significant accumulations of nutrients in the bottom waters was noted at any of the monitoring stations.

The density and composition of the phytoplankton (microscopic water plants) indicated an “unenriched” lake condition. The density and composition of the zookplankton (microscopic animals) indicated “moderately enriched” lake conditions.

***

In summary, Lake Kasshabog had good water quality during 1978, but is considered oilgotrophic, bordering on mesotrophic. Any further shoreline development on the lake should be carefully planned and constructed to minimize or eliminate the addition of plant nutrients to the lake.

Soils and Climate

(Pg. 9)
“Much of the Northern part of the County is under forest and managed by the Ontario Ministry of Natural Resources…There are extensive areas suitable for recreational use around the numerous lakes. Thousands of cottages dot the shorelines; many developments are under way to meet the almost insatiable demand for recreational land.
Strict controls on cottage density and sewage and garbage disposal must be maintained if eutrophication of lakes and unsightly environment are to be avoided. Many shorelines are rocky with thin soil cover and unsuitable for septic tanks unless costly installation procedures are followed.

 

(pg. 8)
There is a large hectarage of very poorly drained depression basins in the southern part of the county with water table levels at or near the surface for most of the year. These are valuable holding basins retaining large quantities of water which would be drained away and lost to the county. Most of these areas should remain in their undrained state to aid in maintaining groundwater levels.

The Fish of Kasshabog

The joy of catching a fish is a great one; let’s keep the opportunity alive by practicing “Catch and Release”, so the fish can spawn another generation of rod-bending offspring!!!

 

Remember to take care when fishing on the bottom near-shore – there are underwater phone lines, water intakes, and anchor lines all ready to grab your favourite lure!

 

Sportfish in Lake Kasshabog include: Smallmouth Bass, Muskellunge, Walleye,  Largemouth Bass, and Rock Bass. Lake Kasshabog is in Fisheries Management Zone 15.
