My Watermark is Christie Lake, Ontario.
Christie Lake is close to where I live. I've enjoyed canoeing, kayaking, and watching loons and otters there. But even closer to home, I visit our local marsh daily. There I monitor amphibians for the Marsh Monitoring Program each spring, noting the changes in population and habitat.
It's the interconnections between waterbodies I find so fascinating and important to protect. Our local marsh takes in water and sends it off again down the watershed. The Tay River flows into and out of Christie Lake, connecting a series of lakes from Bobs to the Lower Rideau. These are not discrete, still bodies... water is life.
