Take a look. Can you see how the water is "boiling" with herring (fish that are also called alewives)? Look at those fins sticking up!
They're all swimming upstream, against the river, to reproduce!
These fish successfully made it over this step. It's not unusual, however, to see fish fall back as they get tired from swimming so hard.
Once they get over a step, they can rest a bit on the edges of the ladder where the water doesn't flow as fast.
Here's a video I shot yesterday. It's a bit hard to see, but you can get a feel for how many fish are there.
I sure am glad that traveling isn't as hard for me as it is for these fish!
Have you noticed any new animals migrating in your area? Many songbirds have appeared in our area over the last few weeks. How about you?
