In 2007 KUR team found that Weeki Wachee Springs is the deepest naturally formed spring in the United States at a depth of 407 feet.
From May 22 until August 30, 2007, the discharge level at Weeki Wachee spring dropped to a level that allowed for cave divers to gain effective entry into the cave system at the spring. The KUR team successfully executed exploration dives and the necessary in-water decompression to explore approximately 6,700 feet in multiple passages at an average depth of 265 Feet Fresh Water (ffw) with a maximum depth of 407 ffw.
