Watershed Conditions Statement - Water Safety
Unseasonably mild temperatures are in the forecast with a high of 9° expected on Thursday. Periods of rain will begin this afternoon and continue into Thursday. Between 15 mm and 25 mm of rain is expected in the Maitland and Nine Mile River watersheds over the next 24 hours. Given the current snowpack, this will result in approximately 50 mm to 60 mm of runoff.
While significant flooding is not expected at this time, levels in streams and rivers may reach or exceed bankfull conditions resulting in some minor flooding in low-lying areas. Municipal officials should monitor low-lying and flood-prone roads.
As temperatures rise, river ice will begin to break up and move. This may cause ice jams to form.
We remind people that slippery and unstable streambanks and cold water temperatures will create hazardous conditions around all watercourses. Ice conditions will also become extremely dangerous as temperatures and river flows rise.
Temperatures are expected to drop sharply by Friday evening. This quick drop could result in the formation of frazil ice in the Port Albert area, potentially leading to flooding in that area.
Maitland Conservation is monitoring watershed conditions and will provide an update if warranted.
This message is in effect until 9:00 a.m. on Monday January 15, 2018.
