Focused on improving water quality
in the lakes
Friends of Catherine and Channel Lakes’ mission is to maintain the sanctity of Lake Catherine and Channel Lakes, to continuously improve and maintain the lakes’ ecosystem, and to establish and implement value-enriched programs to enhance the overall quality of lake life.
Our goal is to return Lake Catherine and Channel Lake to pristine condition by eradicating invasive plant species, reducing pollution and increasing awareness about how to care for the lakes. We are doing this through the implementation of a detailed Lake Management Plan.
Please join the cause by getting involved. Many hands make light work.
Lake Catherine and Channel Lake are the northern most lakes on the Chain O’Lakes in Northern Illinois. These two interconnected lakes are part of the Fox River Watershed, serving as a vital drinking water supply for many communities in Illinois, providing habitat for hundreds of species of plants and animals and supplying a beautiful place to enjoy lake life.
Over the past many years, these lakes have suffered from a lack of care. Storm water run-off and run-off from farmlands around the area have created a heightened level of phosphorus and other nutrients in the lake contributing to wide-spread algae blooms in the spring. In addition, invasive species of plants, including Eurasian Water Milfoil, have all but choked out many native species and affected vital fish habitat.
The Friends of Catherine and Channel Lakes aims to improve conditions in the lakes for the betterment of lake like – for humans, plants and animals.
