Checking today, the lake levels went down slightly and then back up slightly over the last 4 days. It's still about a foot over typical levels for this time of year. There is a note in the Operations Updates on the New Hampshire Department of Environmental Services Winnipesaukee lake level page that the dam outflow will be increased to 1920 CFS, its maximum but the Lakeport dam page does NOT reflect that change yet. At 1920 CFS, the lake drops about an inch per day, barring no significant additional rain. That means it will take about 12 days to get the lake down a foot to the typical fall/winter levels. They MUST be able to do that before the spring snowmelt runoff and "April showers" because they cannot dump all that water downstream (downstream is dealing with their own local runoff) in the spring. Instead, they let the runoff fill the lake back up and minimize the impact downstream.
