Keep in mind basic trigonometry. Many of the markers (and boat moorings) are on a "scope" of line from an anchor on the bottom. As the level drops, the "scope" (long leg of the triangle) becomes longer. So, the marker has a wider/longer radius to swing in. I.e., the appearance that it has "shifted".
