On the water at Lake Champlain at Port Henry

A receding shoreline opens up beaches but also uncovers hazards: stumps, rocks and soft mud that are usually well under water.

The water is 50 °F, cold enough for cold-water shock. Wear a life jacket on the water and get in slowly if you swim.

What happens at each level

101.50 ft: Severe flooding occurs, with moderate to widespread inundation of lake side properties and closure of some low lying roads.
100.50 ft: Flooding becomes serious, and wave erosion on windward shores becomes a problem. If lake ice is present, structural damage may occur.
99.50 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.
99.00 ft: Minor shoreline flooding may occur under windy conditions where the action of waves may cause splashover on some low lying lakeside properties.
