ROAD SIGNS

The roadsigns identifying protected areas (the five-meter riparian zone) and the watershed are intended to raise residents’ awareness of the consequences of their actions.

Few people realize when they drive through the Coaticook sector of Barnston, or near the border in Stanstead, that they are in the Lake Massawippi watershed. Every plunge of a backhoe shovel, every drainage installation, every can carelessly discarded anywhere in the watershed may very well have an impact on Lake Massawippi.

Everblue Massawippi reaches out to all passers-by with two types of road signs installed at 30 strategic locations. The first recalls the bylaw prohibiting manicured landscaping within five meters of the shoreline; the second indicates that although nowhere near the lake, the area they are visiting is nevertheless within the watershed of Lake Massawippi.

The signs will be installed in July and August of 2014.
