Idea of Low Tide Icon
There is two lines - - one running vertically and one running horizontally. Both meet at a 90 degree angle. Basically, it is a half of square. Inside the half square is three shapes - - the first is a small rectangle sitting on top of a larger half circle. The top half of the larger half circle is removed and the rectangle is sitting on top with the bottom of the rectangle removed. Below the half-circle is a squiggly line signifying water/waves that runs horizontally.
