The Ohio River is still green

Despite yesterday's steady rain and cooler temperatures, the algae bloom in the Ohio River in my area is still there, although not as visible as it was two days ago. On Wednesday, the afternoon soon gave the river a bright green sheen. Today the river was still green, particularly in the still water close to the shore, but it wasn't as bright as it was two days ago.

Here are a couple of photos I got Sunday. The first one is the result of my skipping a small flat rock in an area thick with the algae.

I was alone, otherwise I could have gotten a photo of the green water splashing upward when the rock first hit the water. Seriously, it was all green.

This one was taken on the upper approach wall of old Lock and Dam 27.

The main stem of the Ohio is on the left of the photo. On the left is an area of backwater where the river comes down and butts up against the shore and the wall. Close to the wall is an area of clear water. You can't see it well here, but a current is flowing along the wall from left to right. To the right out of the picture frame are a series of little whirlpools where the backwater meets the river current.

As I watched this small current move around the guide wall and push the algae out of the way, I had to think that the river current was pushing water downstream. Some of it accumulated where it couldn't go any farther until it backed up along the guidewall.

The white thing in the upper left corner is the reflection of a cloud on the river surface.

Let's see how the river looks tomorrow. Some folks will be watching football. I'll be looking for algae. Such is life.
