Latest Level and Temperature Data from Around Lake Champlain Level Temperature USGS gage at Rouses Point NY 98.04 feet 44 degrees USGS gage at Burlington VT 97.99 feet 41 degrees USGS gage at Port Henry NY 97.95 feet 46 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 the Northern Adirondacks of New York... ...WIND ADVISORY REMAINS IN EFFECT FROM 5 PM THIS AFTERNOON TO MIDNIGHT EDT TONIGHT... .TONIGHT...Cloudy until midnight, then becoming obscured in clouds.
