8:40 PM: Big SFD response is headed for Emma Schmitz Memorial Overlook (map), where two people are reported to be in the water. Updates to come.
8:43 PM: SFD says the two people are “swimmers in distress.”
8:48 PM: Now they’re saying that it looks like the “swimmers” are actually “two divers on the surface” who do NOT appear to be in trouble. But a boat crew will continue that way to check with/on them.

9:06 PM: A rescue-boat crew has just made contact and confirmed the divers “are not in trouble at all.”
