This was actually taken up the Columbia at the Julia Butler Hansen NWR but I thought it would be of interest to folks here.There were hundreds of sea lions in the river. I believe they were following the smelt run: But the coolest thing was a group of about 40 sea lions swimming upriver as a group. They would all splash and jump out of the water for a couple of minutes, then disappear underwater for 3-4 minutes, then appear on the surface upstream, jumping and splashing again. They did not appear to be catching fish, this is just how they were traveling.I took videos of this. Go to and watch the videos in order (1, 2, 3) to watch them swim up the river.
