A FLOOD WARNING remains in effect for the Lake Nipissing Shoreline, La Vase River downstream of Lakeshore Dr, Parks Creek, and the Mattawa River downstream of Hurdman Dam.
"Weather forecasts anticipate approximately 30 mm of rain tomorrow (May 13) followed by several days of no precipitation," said Angela Mills, NBMCA Flood Duty Officer. "The water level of Lake Nipissing has been declining, but conditions in North Bay and Callander may be influenced by wind effect, especially when winds are from the west or southwest."
As Lake Nipissing water levels continue to decline, water levels in Parks Creek will gradually be raised over the next week to match those of the lake in preparation for the operations at the Parks Creek Backflood Control Structure to wind down and stop log removal. Eva Wardlaw Conservation Area is closed to the public while operations remain ongoing.
Mattawa peaked 6 cm above the major flood threshold of 154.8 m. Daily average water level has receded by 51 cm. Water levels are forecast to continue to decline, per the Ottawa River Regulating Committee.
Residents are asked to keep children and pets away from shorelines and watercourses, and to avoid driving through flooded areas wherever possible. For flood emergencies, contact your local municipality. Residents of unincorporated townships should contact the Ministry of Natural Resources – North Bay District.
NBMCA staff will continue to monitor conditions as part of the Authority's Flood Forecasting and Warning Program and will issue updates as needed.
Current flood status and condition updates are available at nbmca.ca, on X (@theNBMCA), Facebook (@theNBMCA), and Instagram (@nbmcainfo).
This message is in effect until Friday, May 15, 2026, at 4:00 PM EDT.

NBMCA cannot assist with active flood response and does not control water levels or operate dams, our watershed is largely natural with very few control structures. The Parks Creek Backflood Control Structure, which prevents Lake Nipissing from flooding upstream into Parks Creek, is the one exception. Where a Conservation Authority has not been established, the local MNR District Office is responsible for Flood Forecast and Warning programs, including along the Ottawa River.
