The back up question is, How long can we drop 1500 CFS before the downstream folks can't take anymore? Other waters empty into the Merrimack River, not just Winnipesaukee.

I found this on Bizer and thought it relevant:

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.
