The flow is the amount of water leaving Lake Winnipesaukee at the Lakeport Dam. It is measured in cubic feet per second (CFS). To put this in perspective, 1920 CFS is enough to fill about 45 swimming pools each minute. For a period of 24 hours, 1920 CFS yields 1.24 billion gallons, or enough water to lower the level of Lake Winnipesaukee one inch. The flow fluctuates depending on the time of year and the lake's height. The long-term average is about 550 CFS.

So 1400 is not quite an inch drawdown per day. Of course there is additional run off after a big rain storm and the normal inflow sources that need to be balanced. However, at this rate it will come down in less than a week. And again, the dam is being actively managed and NOT "closed".
