Latest Level and Temperature Data from Around Lake Champlain Level Temperature USGS gage at Rouses Point NY 97.07 feet 55 degrees USGS gage at Burlington VT 97.09 feet 53 degrees USGS gage at Port Henry NY 97.15 feet 50 degrees Early in the boating season, water temperatures on rivers, ponds and lakes remain rather cold. Immersion in cold water can be life threatening very quickly due to hypothermia and the bodies inability to work efficiently in the cold water. Therefore, it is recommended to consider postponing small craft boating activities until water temperatures become warmer. However, if you choose to venture out, wear all recommended cold water protective gear, including a life jacket, in the event of an accident. && .The Higher Summits Forecast for Vermont and Northern New York... .TONIGHT...Partly cloudy until midnight, then becoming cloudy.
