What is the word camp green lake and you always think it has to be green and there must be a lake?

"Camp Green Lake" is a fictional setting from Louis Sachar's novel, where the name is misleading. Despite its name, the camp is located in a desolate, dry area with no lake in sight and is characterized by harsh conditions. The irony lies in the contrast between the expectation of a lush, green environment and the stark reality of the camp's barren landscape. It reflects themes of hardship and the transformative experiences of the characters.
