Flood Warning

Bancroft District


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.

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


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



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.
