KLSA Paleo Study Information

Here is further information on the latest KLSA project in conjunction with Trent University, Queens University, Kawartha Conservation and the Stony Lake Heritage Foundation. This Kawartha Lakes, Paleolimnological Study has started already with the collection of the three sediment cores, obtained in Cameron, Pigeon and Stony Lakes. KLSA has funds to complete the study on two of the sediment cores with the third being completed when additional funds are raised. KLSA continues to fundraise in support of this project and your donations would be greatly appreciated.

Kawartha Lakes Paleolimnological Study


KLSA with our partners, Trent University and Queens University (Paleoecological Environmental Assessment and Research Lab) have initiated a new study entitled: Kawartha Lakes Paleolimnological Study Collection, Analysis and Age-dating of Sediment Cores: “Understanding past to plan for the future”. We are collecting and analyzing sediment core samples to determine the range of variability in vegetation and metals accumulation over the last 200 years. In 1986, MOE collected sediment cores in Sturgeon and Rice. The study concluded the greatest sediment accumulation rates occurred during the last 50 years (1930s to 1980s). Nutrient loadings accounted for most of the additional accumulation, giving rise to accelerated eutrophication of the lakes (this report is on the KLSA website – see Figure 6). If the trend is still occurring, Lake Managers can use this information in setting realistic mitigation targets for aquatic systems. Three have been selected: Cameron Lake, Upper Pigeon and Stony Lake. See the attached map. Stay tuned for more information as it becomes available.
