Severe and Flash Flooding

Connecticut and its cities, towns and tribal nations, are susceptible to flooding throughout the year in both the summer and winter months. Numerous rivers run through Connecticut and the state contains the estuaries for several major rivers.

Flooding of these rivers can occur due to heavy rainfall or snowmelt in Connecticut or other parts of New England during the Spring months and at other times of the year. Additionally the Connecticut shoreline can be susceptible to coastal inundation; thus it is important to  "Know Your Zone!" if you live in a  coastal community. It is important to remain prepared for such events and to Stay Informed during severe weather and flooding situations.

Flash Flooding and River Flooding

Historically flooding has caused a significant number of federally declared disasters in Connecticut. Larger Rivers in Connecticut Include: The Housatonic, The Connecticut, The Farmington, The Thames, and The Naugatuck Rivers. In addition to these larger rivers, Connecticut has many smaller streams, brooks, and rivers that are also susceptible to flooding throughout the year.It is always important to stay informed about ongoing weather situations which may result in flooding.

In addition to river flooding, flash flooding may occur in urban environments which have increased impervious surfaces and the lack of sufficient drainage. If you live in one of  these areas susceptible to flooding, It is important to remain informed during severe and rapidly changing weather situations.

Flooding Preparedness Tips

  • If you live on the Connecticut coastline; "Know Your Zone!" in case of the need for evacuation do to coastal flooding.
  • Those who live in low lying areas who have experienced flooding in the past should expect flooding once again. New home owners who live in flood plains should take note of their surroundings and stay alert of potential flooding.
  • Those who experience flooding should work closely with their local police, fire, emergency management, and other emergency support organizations to monitor the situation.
  • Use common sense and evaluate your situation:
    • Motorists should use caution driving and not venture into areas where water has collected.  People often underestimate the force of flood waters and think they can drive through the areas.
    • Do not drive, wade or enter into any flood zones.
    • Evacuate if told to do so.
    • Move to higher ground or a higher floor.
