Visiting a beautiful lake or pond surrounded by mixed woodlands or sprawling prairie is one of the most serene and relaxing things I can think of doing on any given day. Nothing beats hearing the hum and buzz of surrounding wildlife, feeling the gentle breeze on my face, and looking down upon the refreshing clear water. Wait, what? Pool-clear lake water? That’s not right. Healthy lakes and ponds typically have a slight greenish/brown hue to them, an indication they contain an ample amount of phytoplankton, the base of the food chain. Being too clear is often a sign that something is afoot in that aquatic ecosystem.
