Hydroelectric Plant Sluice Gates: 2018

Whoa! The extraordinary river flow of 2017 caused some pretty drastic long-term changes to the HydroElectric Plant route.

Perhaps the most obvious is the change in the sluice gates.

This is what they used to look like:HE-Plant-Sluice-Gates---My-Sketch labelled-web

But this is what they look like today! It appears I need to resketch my sketch!09-HE-Plant-boards-gone-2018

The boards have been blown off and are now lying here and there around the gates, some in front, some inside the headpond. They went every-which-way from the constant eddies in front of and beyond the gates.

So… now you have to pay attention to the debris in front of each gate to know where you’re at, since the gates themselves all look identical. My photos aren’t the best at the moment because the visibility was bad the day I had a close look. But they’ll give you an idea.

Gate 1 (closest to shore):

Here’s what it looked like in 2016: 5 boards in place above the concrete sill.

Here’s what it looks like today:

The 5 boards are gone. Weeds cake the posts but they remain solidly in place. (Note the indentations in the canal wall. They were for “stop logs” – beams which were slid into them to slow or stop water flow if repairs were required on the gates themselves.)

The gate height is (obviously) lower and the hill of silt in front is higher so that as you approach, the current threatens to carry you over the gate before you’re ready. Be wary.

Gate 2 (middle):

Here’s what it looked like in 2016: bottom and top board in place. This photo was actually taken from inside the headpond – looking back towards the gate.

No boards. And no weeds – hmmm.

Gate 3 (furthest from shore):

In 2016, there were no boards on top… just like today!

The debris in front of each gate differs. I’ll work on getting some shots of each and pass it along to you!
