News Flood watch issued for the Mattagami watershed SHARE ON: Melissa Candelaria, contributor, Wednesday, May. 7th, 2014 The Mattagami watershed is under a flood watch. The Upper Mattagami River Water Management Committee says many of the area rivers and streams are still rising because of the continuing warm weather and melting snow. The water levels on the Mattagami River system could reach the first stage flood level which could cause flooding in low lying areas. Levels on Porcupine Lake, Town Creek and Crawford Creek are in good shape. If you live in the flood prone areas, remove any unsecured items from the shoreline, have an emergency plan in place and keep your children away from fast flowing streams and rivers.
