Flooding

  • Flooding in Newfoundland
  • Flood Risk Mapping Studies / Public Information Maps
    • To help support climate change adaptation, these flood risk mapping studies are being updated and new ones undertaken using climate change projections.  A brochure is available outlining Government’s New Template for Climate Change Flood Risk Mapping.

  • Badger Water Level Information
    • Badger Flood  2003 Situation Report
      The Town of Badger has a long history of flooding dating back to 1916. However, the February 15 event was the most severe in terms of depth of inundation and damages to the town. The mechanism was also different, particularly with respect to the rate of rise of the water level. This report provides a description of the event, outlines the data that is available to carry out further investigations, describes the response of the Water Resources Management Division (WRMD) and other agencies to the flood event and makes conclusions and recommendations.

  • Monitoring Snow Extent and Snow Water Equivalent on the Island of Newfoundland
    Snowfall accounts for a significant percentage of annual precipitation in virtually all regions of the province. During the spring months melting snow is a major supplier of water to reservoirs, lakes, and rivers and through infiltration, soil moisture and groundwater. Rain-on-snow events, during the snowmelt period, greatly increases the risk of flooding to people and communities located along the province’s lakes and rivers. Snow monitoring provides essential information for flood forecasting, hydropower generation, wildlife studies, drinking water reservoir operation, and for climate change adaptation in the province.
  • Hurricane Season Flood Alerts
    The Hurricane Season Flood Alert System (HSFAS) is based on forecasted precipitation amounts and seeks to provide communities with flood warning services as a key climate change adaptation and public safety tool. Alerts are provided to communities that have Flood Risk Mapping Studies (FRMS) or have published intensity-duration-frequency (IDF) curves from which precipitation based flood triggers can be derived. The HSFAS is to help communities in the province prepare for storms and avoid future high-cost expenditures in repairs and damages. The HSFAS is operational during the peak hurricane months of June to December.
  • Near Real Time Streamflow and Climate Information
  • Regional Flood Frequency Analysis for Newfoundland and Labrador (2014)
    The annual cost of flooding to public property in Newfoundland and Labrador is estimated to be in the millions of dollars range. Accurate flood flow estimates are needed for the efficient design of instream structures (culverts, bridges, spillways, etc.) and for floodplain management. The locations for which flood flow estimates are required usually do not have streamflow data which could be used to directly estimate the flood flows. This study, like four previous studies (1971, 1984, 1990, 1999), derives a set of equations for estimating return period flood flows in ungauged watersheds. The 2014 study is the first to provide equations for Labrador.
  • The Floodplain Belongs to the River - A video created around 1987 showing many scenes of flooding in the Province of Newfoundland and Labrador. This film was a project under the Canada -Newfoundland Flood Damage Reduction Program and its message is that development should not occur in a floodplain.
