Lake Nose is a lake near Danville. It is said that it is the home to "Nosey", the Lake Nose Monster. Phineas and Ferb found him but didn't bring back any proof after they realized that he doesn't want to be discovered.
Bob Webber (Aunt Tiana's husband) works there as a life guard. He also sells Nosey T-shirts and snow-globes, "Kid with Cramp" snow-globes, and Lake Nose hats and T-shirts at the Lake Nose Souvenir Shop.
Lake Nose is a quite unusual lake, as it has a beach with sand and is very narrow (as seen while Mr. Fletcher is telling stories to Phineas and Ferb).
- Candace and Jeremy served as lifeguards for the lake temporarily.
- It is a parody of Loch Ness.
- It is home to The Lake Nose Monster, Nosey.
- The lake was probably named after the mountain on the island in the center of the lake, because it resembles a nose.
