As spring approaches, warmer temperatures and heavy rainfall can lead to quick melting of snow and ice. This can result in higher water levels in rivers, creeks, stormwater ponds, and Lake Ontario. Consequently, the risk of flooding may increase. Discover what actions you can take to stay safe.
With the arrival of warmer weather, snow and ice begin to melt. While this is typical for spring, it also raises the potential for flooding in Mississauga.
The combination of melting snow and rising water levels could pose additional flooding hazards in your area. When significant rainfall occurs on frozen ground, it may cause the city’s rivers, creeks, stormwater ponds, and Lake Ontario to overflow, affecting local parks, trails, and neighborhoods.
Why is flood risk greater in spring?
Spring brings together rapid snowmelt, heavy rainfalls, and breaking ice. These factors can lead to an accumulation of water that exceeds what the ground and drainage systems can manage.
Rapid snowmelt
Warmer temperatures during spring can lead to swift melting of snow. If a large amount melts at once, the ground may struggle to absorb all that water quickly enough-especially if the soil underneath remains frozen. The excess water will flow into rivers, creeks, stormwater systems, and Lake Ontario. This increases both water levels and flood risks.
Heavy spring rain
This season often brings heavy rainstorms. When this rain falls on top of melting snow, it adds more water than the city’s drainage systems can handle at times. This situation leads to rising water levels in nearby rivers and creeks while heightening flood risks in certain locations.
Ice jams
In early spring months many rivers and creeks still have ice present. As this ice breaks apart into larger pieces they may become lodged at bends or bridges along waterways or other narrow spots. Such blockages function like temporary dams which can cause upstream flooding when they break free suddenly; this may create flash floods downstream.
What do flood watches or warnings mean?
Flood watch: Flooding could occur in some areas Flood warning: Flooding is either currently happening or will happen soon
The Credit Valley Conservation (CVC) and the Toronto and Region Conservation Authority (TCRA) issue these notifications when conditions such as heavy rain or melting snow/ice buildup might result in rising water levels.
If a flood warning is issued you should act quickly to protect yourself from danger as well as prevent damage to your home from flooding.
Keeping yourself safe
A spring thaw can happen rapidly so here are steps you might want to follow for keeping your family safe during this time.
Stay informed about weather alerts
Please check regularly:
The following resources offer real-time updates on weather conditions helping ensure that you’re aware of any changes that could affect safety levels around you.
You can view Conservation Ontario’s map to find out which Conservation Authority covers your neighborhood within Mississauga-the City collaborates closely with all three local Conservation Authorities monitoring conditions together addressing potential flooding concerns proactively.
Watch kids & pets near waterways
Please talk with children about dangers associated with fast-moving waters unstable riverbanks along with increasing level issues nearby; supervise them closely making sure they avoid areas like streams rivers stormwater ponds plus Lake Ontario where currents may be stronger than usual too!
Pets should also remain leashed away from higher-water zones since shorelines tend toward slippery unpredictable surfaces especially during rapid thaw periods!
Create an emergency plan
<p It's essential that everyone sit down together discussing:
Reviewing preparations concerning potential floods outlining procedures before during after Identifying safe exits leading out from home Updating contact lists ensuring every number saved across devices Making certain everybody understands how/when dial 911
Your home’s protection matters too!
The quick melting process combined with elevated waters intensifies threat levels concerning possible floods so implementing preventative measures now helps mitigate damage occurring within residences later!
Clearing away accumulated snowfall around foundations
Please shovel any remaining frost layered upon surfaces positioned three-five feet distant from structures (as far back as feasible). Don’t forget clearing paths near window wells exterior doors preventing runoff seepage infiltrating basements through low access points!
Maintain clear gutters downspouts eavestroughs
Blocks forming due freezing elements clogging channels restrict smooth flows resulting puddles gathering near foundation borders thus increasing hazards above mentioned! Ensure proper maintenance by safely removing any obstructions present but consider seeking professional assistance if needed! Remember each spout should extend anywhere between three-six feet minimum distances away from dwelling limits!
Inspecting storm drains checking blockage statusIf accessible please remove leaves snowfall debris hindering effective draining capabilities on roadside catchment basins reducing chances facing possible street/property flooding outcomes overall throughout seasons too!(Report issues online via call center options including numbers directly connecting citizens needing assistance.)
