Whatever happened to the whales that swam up that river in California??? Did they ever reach the sea?

Answer 1

The scientists that were tracking the whales lost them when they reached the SF bay, assuming that they went into the ocean overnight (while no one was watching). It is unknown what direction the whales headed, as attempts to attach monitoring devices (locators) were unsucessful. It is hoped that they continued the migration north, but they may have followed a food source in another direction.

It was never figured out why the whales headed inland in the first place. The mother may have been evading predators (there are resident and transient Orcas, as well as Great White Sharks) off the coast and saw the bay as a safe harbor. The mother may have been following prey inland. The calf may have been weak and needed a safe place to rest.

This is not the first time that a wayward whale has made it up the river; there was a whale named Humphrey that did the same thing several years ago.

Answer 2

Yes. Whether due to people's attempts to turn them around, or on their own initiative, they did turn around and swim back out to sea.
While they were in the river, they were given antibiotics to combat the infections they suffered from their accidents with boats, which weren't healing well because they weren't in salt water.
They came out just fine.

Answer 3

yeah they got them out with some nets and the shot them with some GPS locater's
