Fact 11: Crater Lake stands at a height of 6,173 feet above sea level.

Fact 12: The lake has an average depth of about 1,500 feet . 

Fact 13: It’s the deepest lake in the United States, and the 7th deepest lake in the world according to underwater mapping of the lake in 2000.

Fact 16: The intensity of the water’s color is the result of the reflection of blue and green light waves coming off the clear water.

Fact 17:  The lake’s clarity is measured by using a secchi disk.

  • A secchi disk’s goal is to determine the transparency of water. 
  • It is a black and white disk, which is 12in in diameter, that is lowered into water, while it is attached to a cable. 
  • Researchers observe how far the disk goes and if they can still see it.
