Flood Index

Know the warning system

The RVCA issues water conditions statements to inform residents, municipalities and other stakeholders of changing water levels across the watershed.

flood normal

A green gauge means conditions are normal.

flood safety

A yellow Water Safety Statement means rivers could have high flows, unsafe banks, melting ice or other factors that could be dangerous. However, flooding is not expected.

flood outlook

A yellow Flood Outlook Statement is an 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.

flood watch

An orange Flood Watch means flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.

flood warning

A red Flood Warning means flooding is imminent or already occurring in specific watercourses or municipalities.
