TRCA Flood Management Service
A principal mandate of the TRCA is to reduce the risk to life and damage to property caused by flooding. We do this by providing local agencies and the public with notice, information and advice so that they can respond during severe rainfall events with the potential for flooding, and during flood related emergencies. The TRCA's Flood Management Service (FMS) has been developed in order to prepare and respond to our changing environment, the increasing needs of our municipal partners and the health and well being of our living city.

OPP Inspector offers flood safety tips
From the desk of Caledon OPP Inspector Tim Melanson
Environment Canada is forecasting warmer weather and showers over the next couple of days and weeks. Due to the ice storm and large amount of snowfall in the Caledon area, I wish to provide you with safety tips as flooding in certain areas is imminent. Local streams and waterways will become dangerous, especially in the vicinity of culverts and bridges. The forecasted rainfall and warm temperatures in the next week may result in the partial melting of the snow and can result in increased stream flows.
- Remind children to keep away from all bodies of water, regardless of depth.
- Do not walk through moving water. As little as 6 inches of moving water can make you fall.
- If you are in a car, do not drive through flood waters or underpasses. The water may be deeper than it looks and your car could get stuck or swept away by fast water.
- Be aware of areas where floodwaters have receded, roads may have weakened.
- Stay away from downed power lines, and report them to the power company.
- Pay attention to local radio and keep up to date with changing weather information.
- Flash floods can occur within minutes or hours of excessive rainfall.
- Know the difference between a flood watch and a flood warning. A watch means flooding is possible. A warning means flooding is occurring or will occur soon.
- Be prepared, build an emergency kit which includes, water, food, can opener, flashlight and batteries, battery operated radio, first aid kit, medications and cash.
The OPP reminds all members of the public to be aware of their personal safety at all times. The OPP's website, www.opp.ca, contains a number of useful resources, tips and links.

"Flooding Happens; it's only a matter of time!"
Mike Walters, Source Water Protection Manager, Integrated Watershed Management Director, Conservation Ontario
It's been less than two months since severe flooding devastated Calgary and much of southern Alberta and closer to home disrupted the lives of tens of thousands of Toronto area residents, stranding motorists and leaving homes without power. For most people who were not significantly affected, these events are already fading and becoming a distant memory. However, for those who lost loved ones, homes and their possession the loss and suffering continues as they try to return their lives to some semblance of normalcy.
These catastrophic events remind us of what could happen to countless people that continue to live within floodplains throughout Canada.
