Lake Silencio

Lake Silencio was located in Utah. On 22nd April, 2011, the Eleventh Doctor brought his companions to the lake for a picnic. At one point during the picnic, Amy Pond saw a member of the Silence off in the distance, but promptly forgot about it when she looked away. During the picnic, someone in an Apollo spacesuit emerged from the lake and shot the Doctor three times, killing him. Amy Pond, Rory Williams, and River Song placed his body into a nearby boat, set it aflame with gasoline provided by an elderly Canton Delaware, and pushed it into the lake's water.

The Teselecta's database contained a record of the Doctor's death at this lake, and revealed that Melody Pond was the woman who killed him. (DW: Let's Kill Hitler)

When abducted by the Silence and Kovarian, River Song was placed in an Apollo spacesuit and submerged in the lake, apparently to await the Doctor. (DW: Closing Time)
