The CVCA monitors weather information, river flows, snow pack and ice conditions in order to predict when floods will occur and how high the water may rise. When flooding is possible, or about to occur, the Crowe Valley Conservation Authority issues flood messages to municipal emergency management officials and the media.
As a result of a review of flood message terminology, Crowe Valley Conservation Authority and Conservation Authorities across the province are introducing some changes effective immediately. These changes will ensure that Conservation Authorities use consistent terminology in line with that used by other agencies such as the Ontario Ministry of Natural Resources, Environment Canada and the Weather Network.
Flood Messages and What They Mean
The Crowe Valley Conservation Authority issues 4 types of messages, depending on conditions: 1. Normal 2. Watershed Conditions Statement (with 2 variations:"Water Safety" and "Flood Outlook") 3. Flood Watch 4. Flood Warning | No flood conditions exist |
 | High flows, unsafe banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, pets, etc. Flooding is not expected. |
 | Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion. |
 | Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare. |
