The lake level is dropping quickly. It lost about 2.6 inches in the past week. Normal loss this time of year is about 1.2 inches per week.
The lake level is a bit below the fall datum used for Bizer's chart of Winnipesaukee, so be very cautious in shallow areas.
In response to earlier posts, I'd like to point out that Winnipesaukee's normal annual fluctuation of fifteen inches or so is pretty small for a lake of this size. Lake Champlain, for example, typically fluctuates about five feet over the course of a year. The Great Lakes each fluctuate about three feet. Lake Powell, Utah, fluctuates so much (up to fifty feet per year) that there's a web site listing which launch sites are open.
