*Bottom
- "Secchi Disk Was Visible On Bottom":
When the Secchi disk is still visible on the bay floor it
means that the water is clear enough for light to penetrate
to the depth of the disk, reflect off of the disk, and reach
the surface of the water again. Most of the time, this means
that there is enough light for submerged
aquatic plants to grow to that depth.
