What the water does
National Weather Service impact statements for this gauge, in the Weather Service's own words.
| 99.0 ft | Minor shoreline flooding may occur under windy conditions where the action of waves may cause splashover on some low lying lakeside properties. |
|---|---|
| 99.5 ft | Minor flooding is expected with water beginning to enter some lake front properties. Water also begins to threaten low lying roads, piers, and docks. Wave action can compound flooding on windward facing shorelines. |
| 100.5 ft | Flooding becomes serious, and wave erosion on windward shores becomes a problem. If lake ice is present, structural damage may occur. |
| 101.5 ft | Severe flooding occurs, with moderate to widespread inundation of lake side properties and closure of some low lying roads. |
