The tides would prevent it
In the spring, right about the time of iceout (middle two weeks of April is normal), the tides on the lake are at one of their high points of the year. Spring tide its called. http://www.winnipesaukee.com/forums/...ead.php?t=1407 > This keeps the water moving enough to prevent the ice from reforming, along with the strong sun as was previously mentioned. It would take some episodic event, like a series of vocanos or a meteor strike, to darken the skys enough to flash freeze the lake in April, once it had thawed.
