Lake Yuron

From Memory Alpha, the free Star Trek reference.

Lake Yuron is one of the few bodies of water on the planet Vulcan.

In 2375, Ensign Tom Paris noted that the Varro's environmental systems were so advanced, they could create "a little taste of home" in Lieutenant Commander Tuvok's quarters, specifically noting the shores of Lake Yuron during springtime. (VOY: "The Disease")
