I love humor, but I'm sure Newcomers question was serious.
Unlike a lot of other lakes, Winnipesaukee is not "drawn down" per se. The outflow from the Big Lake goes through the various lakes to the Winnipesaukee River and then to its confluence with the Pemigewasset River to form the Merrimack River. The controlling of the outflow is a delicate balance between ensuring adequate levels to provide for the spring runoff in the vast Winnipesaukee watershed while providing an adequate flow for dams and power stations downstream. It's a delicate balance to say the least. As others have said, it will likely go down to about 1.5 ft below full lake.
That being said, be careful anchoring so as to avoid snagging the large rubber stopper on the lake bottom. The results there could be catastrophic.
