MRC PONTIAC – The Ottawa River Regulating Committee has warned that levels and flows along the main stem of the Ottawa River will remain high and are susceptible to further rise this week in all locations due to recent rainfall. Minor flood levels will likely be exceeded in multiple locations and major flood levels may be exceeded in flood-prone areas, with levels expected to remain well below 2019 on the main stem of the Ottawa River. Areas of primary concern are:
• ILES-AUX-ALLUMETTE / LAKE COULONGE: Levels could reach peak levels observed last week and possibly exceed them by 20 to 25 cm.
• QUYON / CHATS LAKE: Levels could reach peak levels observed last week and possibly exceed them by 10 to 15 cm.
The latest forecast shows that the Ottawa River water level on May 3 will be 113.25 in Pembroke and 108.40 at Lake Coulonge.
According to a CHIP 101.9 FM web report, three roads in local ZECs are currently impassible due to severe washouts, affecting access to the territory as well as several vacation leases. In ZEC St-Patrice, chemin Schyan is impassable between kilometres 10 and 12.3. In ZEC Rapides- des-Joachims, chemin Rapides-des-Joachims is blocked between kilometres 10 and 11 and in ZEC Pontiac, chemin du lac Ward is closed at kilometre 23. The situation on chemin Thomas-Lefebvre in Mansfield is now too dangerous and the road is completely closed between addresses 175 and 181, to all traffic.
