Last week began with rain, which is just a gray way of saying the lake level is going up. Despite a general flatness on Lake Lucerne, nobody skied between those drops.
One reason, perhaps the most relevant reason, for the lack of skiers is the lake's temperature. Forty six degrees Fahrenheit is a wee bit nippy. Such temperatures add way too much physical and emotional trauma to boat towed types (skiers, knee boarders, footers).
