The information below was quoted from the Ministry of Natural Resources and Forestry – North Bay District Bulletin: Tuesday, April 23, 2019 . 16:30 HRS
The Ministry of Natural Resources and Forestry – North Bay District is advising area residents that a Flood Watch continues to be in effect in the northern portion of the District which includes the Matabitchuan, Montreal, and upper reaches of the Sturgeon River Watersheds as well as southern portions of the District on the Restoule, Pickerel and Wolf Rivers until Friday, April 26, 2019.
Water levels and flows in local lakes and rivers will remain high following significant snow melt and rainfall that has moved across the area.
Residents and those visiting the area are advised to be aware of current watershed conditions. Higher than normal water levels and flow conditions, typical of this time of year, exist throughout the area and residents are reminded to keep a close watch on weather conditions, regularly check for updated messages and exercise caution near fast-moving rivers and streams. It is expected that lower-lying portions of known flood-prone roads along river courses will be impacted to various degrees as lake/river levels increase over the week. Banks and shorelines adjacent to water bodies are extremely slippery and unstable. Residents and visitors should exercise caution while around water bodies and maintain close supervision of children and pets. Residents that may be affected by high water conditions should take necessary action to protect/secure any vulnerable property in proximity to rivers and lakes and closely monitor developing conditions.
The Ministry is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.
Description of Weather System
Daytime high temperatures are forecast in the 9 to 14 degree Celsius in the area. Night-time low temperatures are largely forecast to remain at or above or just below 0 degrees Celsius in the area. Additional rainfall amounts of 15 to 30 mm are expected today in the northern portion of the District. This will bring total rainfall amounts up to 50 mm by this evening across the northern portion of the MNRF North Bay District.
Mid-April snow surveys show a continuing snowpack of between 16 cm to 93 cm and ranging from 33 to 221 mm of snow water equivalent. These values are above average to well above average for this time of year.
Description of Current Conditions
Water levels and stream flows across the North Bay District are elevated from ongoing spring snow melt and past precipitation events.
The impact of recent warm temperatures and rainfall have compacted the significant snow pack reducing its ability to absorb rainfall. The forecasted warm temperatures and precipitation are likely to further degrade the snowpack and river ice and continue to produce runoff and increase levels and flows. Warm temperatures in advance will deteriorate snowpack and further prime it for release and melt.
Risks may include degradation of river ice and ice jam related flooding from increasing temperatures and flows, fast moving cold water with rapidly changing conditions, and flooding of low-lying areas with a history of flooding.
A close watch on local forecasts and conditions is recommended.
