MNR Flood Warning – Bancroft District

NEWS Thursday, April 10, 2014

(5:00 pm)

The Ministry of Natural Resources – Bancroft District is advising area residents that a Flood Warning is in effect in the District. If your house gets flooded, then get some emergency help.

Residents of Bancroft District should take necessary action to protect property and monitor developing conditions closely. People are asked to stay away from fast-moving rivers and streams.

MNR  is  closely  monitoring  the  weather  and  developing  watershed  conditions.  Further updates will be issued as appropriate.


Description of Weather System

This message is being sent on the basis of information received from MNR – Surface Water Monitoring Centre, MNR – Aviation Forest Fire and Emergency Management Services, Trent Severn Waterway and Environment Canada.

Warmer temperatures are expected to continue over the next five days with daytime highs of +10  degrees  C  with  the  potential for  15mm  of  rain  Thursday  through  Friday. We  are monitoring a large weather system that is set to move in to the province Saturday evening and remain over the weekend and into early next week.  If the storm hits our region as is currently forecasted, we could receive 50+mm of rain from Saturday night through Monday with a five day precipitation total of 80-100mm.

Description of Current Conditions

Although some of the snowpack has melted over the last week, a significant amount of snow is still present. There is a snow water equivalent in the snowpack of approximately 115-120mm. Mild temperatures combined with the significant forecasted rainfall will rapidly melt the remaining snow and will quickly increase water levels and flow velocities in local rivers and streams. Smaller streams and creeks are expected to respond quickly to the additional runoff,  but  larger  water bodies,  including  the reservoir  lakes,  will take longer to  react.

Municipalities and residents should closely monitor low lying and flood prone areas along the Burnt, Irondale, Gull, and Black Rivers as well as the York and Madawaska Rivers. These water bodies are expected to respond quickly to the rapidly melting snow and forecast rainfall. Additional water accumulation in areas adjacent to watercourses, road ditches and areas with poor drainage will occur. Road overtopping is possible in some locations. With the combination of double digit temperatures, forecasted precipitation and remaining ice cover on local lakes and rivers, there is the potential for ice jams to form which could contribute to elevated water levels and flooding.

The water levels of the reservoir lakes are rising at a slow rate. Trent-Severn Waterway (TSW) officials advise that the winter drawdown of the lakes has created significant storage capacity and currently there are no flooding concerns for lake shoreline areas. TSW staff assess the situation daily and undertake dam operations as required. The MNR and the TSW continue to closely monitor local lakes and rivers as the freshet progresses.

The  MNR  is  in  regular  communication  with  partner  agencies,  including  Conservation Authorities, Ontario Power Generation (OPG) and the TSW.

Expiry Date:  This message will expire on Monday, April 14 2014, 12:00 PM
