How healthy are Canadian lakes? To answer this question, we must monitor lake health and the threats posed by human activities, but to date, there has been limited coordinated action to monitor lakes, especially to compare current and historical data. For many lakes, we have little relevant data.
This is a problem faced by policymakers, lake associations, municipalities, lake managers, scientists and the general public. It affects decision-making at a time when lakes are threatened by multiple and complex factors.
