Mississippi Valley Conservation is issuing an update to the March 31, 2008 Flood Advisory for all watercourses across the Mississippi Valley watershed and the Carp River.

Flows have increased in ditches, smaller streams and the Carp River as a result of the recent rainfall and snowmelt from the warmer temperatures. This trend is expected to continue through next week as the forecasted temperatures during the day remain above freezing. The Carp River will respond quickly to the melting snow and rainfall forecast over the next few days and the overtopping of its banks is likely to occur as early as Friday. The Carp River is not expected to peak before early next week and based on current forecasts, water levels are expected to be similar to those experienced in 1999.

Flows along the major tributaries of the Mississippi River, the Clyde and Fall rivers, are just beginning to increase. Based on current long range forecasts, water levels are not expected to peak for at least another week. Water levels on Mississippi and Dalhousie Lakes have not yet started to increase and no serious flooding is expected to occur on these lakes for at least a week. The potential for above average flooding across the Mississippi River watershed remains high. There is also the potential for ice jamming to occur as river and lake ice begins to break up. Residents are advised to keep a close watch on conditions in their area.

MVC reminds the public that spring water conditions pose a serious threat. Water levels can rise in a short period of time and near freezing water temperatures can quickly produce hypothermia. Parents are reminded to warn children to stay away from watercourses and ditches during this time. At this time of year, it is recommended that all persons stay off ice covered bodies of water.

MVC’s flood forecasting and warning program includes: monitoring weather conditions, measuring water content of snowpack, estimating expected river flows and water levels and issuing flood advisories or warnings as required. In a flood situation, the conservation authority provides early warning and continuous monitoring and analysis through the event to municipal and provincial emergency response personnel regarding the expected severity and duration of the event.
