Description of Lettuce Lake Spring

  • Lettuce Lake Spring is situated within Lettuce Lake, a shallow and crystal-clear water lake.
  • The lake’s bottom is covered with dark detritus, providing a unique underwater landscape.
  • Lettuce Lake boasts a diameter of 150 feet, offering ample space for exploration.
  • The spring vent, where the water originates, is located at the center of the lake and reaches a depth of 8.8 feet.
  • During a visit in March 2003, it appeared that the spring was not flowing, and there was no observable boil on the spring’s surface.

Natural Features

  • A notable feature of Lettuce Lake is a 6-foot-high berm that runs along the lake’s southern side.
  • In the past, the natural spring run used to flow southward out of the lake before canal construction.
  • However, the berm now obstructs the natural outflow, causing water to exit the pool in a southwestward direction.
  • This water flows through a 200-foot-long canal, which is 1 foot deep and 6 feet wide.
  • Subsequently, it enters a slightly larger canal that extends an additional 650 feet southward before eventually connecting to the Tampa Bypass Canal.
