Toronto - The conservation authorities in the GTA and Golden Horseshoe Area remind the public of the dangers that exist on our streams, rivers, ponds and lakes during spring breakup.

The cold weather and snow that we have been experiencing since the middle of January has resulted in the development of significant ice covers along most of our rivers and streams, and a build up of the snow pack in our watershed. With the snow melt from warming weather, the potential for flooding and ice jamming remains significant should heavy rains also occur.

This spring is expected to bring melting snow, rain and breakup of ice along rivers, streams, ponds and lakes. During this time of year higher, faster flowing water is expected. Also, ice cover may weaken and become thinner with little or no warning, therefore all ice-covered waterbodies should be considered dangerous. Slippery and unstable stream banks and extremely cold water temperatures can lead to very hazardous conditions close to any water body.

Conservation authorities are closely monitoring river and stream conditions and will prepare flood messages as conditions warrant. Parents and caregivers are being asked to keep children away from stream banks, ponds and lakes. Conservation authorities is asking the public to exercise caution around any water body over the next few weeks and help make this a safe and enjoyable spring.
