Potential for some flooding in the next 24 hours

Local conservation authorities have issued statements regarding the amount of rain in the forecast combined with mild temperatures that will result in heavy run off for the next day or so. 

Here is the statement from Saugeen Conservation

Forecasted rain and unseasonably warm temperatures will result in rising water levels across the Saugeen River Watershed over the next few days.

Temperatures are expected to reach the low teens by Thursday afternoon, which will result in a rapid depletion of the existing snowpack.

Across the watershed the snowpack currently holds a range from 0 – 90 mm of water equivalent. Soils are currently saturated, which means melting snow and any additional precipitation will run off quickly into local waterways.

While significant flooding is not expected, watercourses could reach or exceed bank-full conditions, with minor flooding in low-lying areas.

There may also be a potential for ice jam related flooding on streams and rivers should significant ice break up occur.

Municipal staff should monitor problem areas and prepare to close low-lying roads.

Residents are reminded to use caution near all watercourses as the water is cold and streambanks are slippery at this time.

Parents are encouraged to keep their children and pets away from streams and off frozen water bodies.

This message will remain in effect until 11:00 am on Monday, March 18th, 2019, unless local conditions warrant further updates.

Saugeen Valley Conservation Authority (SVCA) will continue to monitor watershed conditions.

 

Grey Sauble Conservation issued this alert ~ 

With the forecasted warmer weather and potential for rain over the next three days, the existing snow pack will be significantly reduced. 

Snow cover (water content) is highly variable throughout our watersheds with some areas having up to 15cm (6”) of water content. 

Most of the rest of the watersheds are around 7.5 cm (3”) to 10 cm (4”) with some areas in the lower range of 2.5 cm (1”) to 5 cm (2”). 

After the minor melt we had this past weekend, soils are saturated under the snow and any new snow melt will quickly run off to ditches, streams and rivers. 

Flows will increase but are not anticipated to exceed average/normal spring runoff levels. 

Although unusual flooding is not expected at this time, seasonally flooding of low-lying areas will likely occur. 

However, there is a concern regarding the potential for ice jams. 

We are still noting lots of ice cover throughout our watersheds. 

Increases in water levels will likely mobilize the ice sheets and they may cause jamming and localized flooding. 

Grey Sauble would like to remind everyone that during spring runoff events, potential conditions exist that could pose a risk to personal safety.

High flows, unsafe banks, melting ice or other factors could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc.

Grey Sauble staff will continue to monitor the weather and the flows and provide additional updates as needed.  Watershed residents can access snow, stream flow and rain gauge data through our Watershed Conditions page on our website (http://www.greysauble.on.ca/water-management/current-watershed-conditions/).
