It's a problem in late winter, the ice 'rots' in a manner of speaking, but for about a month and a half at least the ice is rock solid. The ice near the shore gets broken up and refrozen as the lake's level changes, but there is really no current where I am. A lot of wet snow on thin ice over extended warm periods isn't good, but a few inches of dry or crusty snow after a hard freeze is great, especially on the first warm day in weeks
