In January 2013, the Minnesota PUC approved a plan to convert the plant to natural gas by 2020. In addition, Otter Tail will install pollution controls at the plant by 2015.[7] In 2019 it was reported that the facility will not be converted but replaced by a new powerplant with a 245-megawatt natural gas combustion turbine, to be build southeast of Watertown in east central South Dakota. The facility will be known as the Astoria Station.
This was originally the site of a hydro plant. They built a new steam power plant in the middle of the 20th Century.

The leather belts caught my eye in this view.
It has gotten to the point that any satellite image that still shows a coal pile is worth noting. But I also wanted to understand the hydro plant. The blue circle highlights the plant; green is the headrace; yellow is the tailrace; and red is the surge tank.
Diversion dam:
The entire water flow. The diversion dam is in the upper-right corner and the plant is near the lower-left corner.

I made sure to include the surge tank on the left.
Some photos from a photo album at
otpco. This site also has a couple of videos about the plant's retirement that I did not bother to watch.
