Aquatic Habitat and Benthic Macroinvertebrate Monitoring of three streams within the Town of Lindsay (2010-2014)

This report provides a brief summary of monitoring results, with the intention of providing background information on the existing hydrological and ecological status of Lindsay streams. These results provide a benchmark.

The Environmental Health of the Oak Ridges Moraine and Adjacent Greenbelt Lands Report Card

This report card provides science-based monitoring data and analysis to help inform the 10-year review of the Provincial land use plans for the Oak Ridges Moraine (ORM) and Greenbelt, as well as reporting on the environmental health of the Oak Ridges Moraine and adjacent Greenbelt lands (i.e. the study area), and recommends on-the-ground actions and additional tools needed to maintain, improve or restore the environmental health of these important lands.

Coldwater Streams Water Temperature Monitoring Report (2011 – 2015)

The Coldwater Streams Water Temperature Monitoring Program has been undertaken by Kawartha Conservation on a yearly basis since 2006. Coldwater streams are particularly sensitive to impacts associated with development and climate change, and are a regulated feature as per the Conservation Authorities Act.

Coarse Taxonomy (tolerance-value averaging) biases Hilsenhoff’s Family-Level Biotic Index
Hilsenhoff’s family-level index (FBI) combines information about the relative abundances of taxa

and their tolerances to pollution. Versions of this index are used extensively in North America to assess water quality.

Aquatic Benthic Macroinvertebrate and Habitat Data on Wadeable Streams from 2004 to 2016

Watercourses are considered regulated features by Kawartha Conservation and as such are routinely monitored through an Environmental Monitoring Program. Biomonitoring using a standard approach to collecting live bottom dwelling organisms, also known as benthic macroinvertebrates, on streams is a core program area. The specific purpose of this report is to summarize data collected from 218 sampling events on shallow streams from 2004 to 2016 to set expectations for what benthic macroinvertebrate communities would be typically encountered within wadeable streams within Kawartha Conservation’s jurisdiction.

Classifying Sites on Municipal Drains in the City of Kawartha Lakes Based on the Presence of Flow and Sensitive Fishes (2018)

This report provides information related to flow conditions and fish communities on municipal agricultural drains within the City of Kawartha Lakes to inform the approval process when undertaking drain maintenance activities. In the summer and fall of 2018, Kawartha Conservation sampled 135 sites on 40 drains according to Fisheries and Oceans Canada’s Drain Classification Protocol.

Rainfall interception on a small forested watershed within the Kawartha Lakes region(1983)

Vegetation affects how precipitation is delivered to the ground. Plants change precipitation amount, timing and area distribution as well as quality of water. Intersection and precipitation data were studied within the Kawartha Lakes region in an effort to quantify the effect of vegetation on the deposition of precipitation. The results can be used in developing of water budgets in the Kawartha Lakes region and other areas with similar hydrological settings.

Watershed Report Cards

In 2012, Conservation Authorities completed development of the Conservation Authority Watershed Report Card Guidelines to assist Conservation Authorities in developing a set of standardized watershed report cards which starting in 2013, are released every five years.

Ontario’s lakes, rivers, streams, groundwater, forests, wetlands and other natural ecosystems contribute to our own health and well-being. They provide safe drinking water sources, filter pollutants, improve air quality and prevent flooding and erosion.

The main challenges to healthy watersheds continue to be the impacts of urbanization and climate change. 

Through their watershed report cards, Conservation Authorities monitor three resource categories: surface water quality, forest conditions and groundwater quality.

Climate Change

Climate Change Strategy - June 2016

This Climate Change Strategy is Kawartha Conservation's response to the current climate challenge facuing our communities and member municipalities. Building on our mandate, our responsibilities and our expertise, Kawartha Conservation is embracing climate change as another challenge to be addressed in watershed management. We recognize that it is critical to incorporate climate change adaptation into existing policies and programs, and prioritize actions that have co-benefits for mitigation and adaptation.

Climate Change Strategy - June 2016

Climate Change Background Paper - June 2015

Climate and weather is different. Weather is constantly changing. Next year’s weather will not be exactly the same as this year’s, and this year is different from the last. The long term average becomes our regional climate. It can be said that climate is what we expect – weather is what we get.
