A lake ball, surf ball or beach ball is an accumulation of plant and other debris formed by the rolling action of waves, into a tight bristly ball which can sometimes be found in the shallow waters of lakes. [1] [2] [3]
The earliest known reference to lake balls is in Walden
There also I have found, in considerable quantities, curious balls, composed apparently of fine grass or roots, of pipewort perhaps, from half an inch to four inches in diameter, and perfectly spherical. These wash back and forth in shallow water on a sandy bottom, and are sometimes cast on the shore. They are either solid grass, or have a little sand in the middle. At first you would say that they were formed by the action of the waves, like a pebble; yet the smallest are made of equally coarse materials, half an inch long, and they are produced only at one season of the year. Moreover, the waves, I suspect, do not so much construct as wear down a material which has already acquired consistency. They preserve their form when dry for an indefinite period.
— Henry David Thoreau, Walden, chapter 9
