Upstream affects downstream

If you live anywhere on this map, you are an upstream resident of the Lake Simcoe watershed. Water drains from the higher points to the lake via a network of streams and rivers both above and underground. Unfortunately this water carries too much phosphorus into the lake. Phosphorus also travels through the air but run-off from urban and rural development is the main controllable source.

If we don't take action, Lake Simcoe will continue to deteriorate.
