The hydroelectric marker for Grand Coulee Dam is not to scale. It should be larger. If drawn to scale it would dwarf the nearby markers.
According to the overview, the map does not include small producers in order to limit the number of markers. For the following sources, only producers above the specified cutoffs are shown:
- Hydropower: above 5 MW (Idaho) or 20 MW (other)
- Natural Gas & Wind: above 10 MW
- Biomass: above 1 MW
Is there a reason Hoover dam isn't on there? With a capacity of around 2000MW it should be a pretty big circle, but it isn't even listed in the drop down menus.
Good catch. That's a major omission. I don't know why it isn't included.
Glenn Canyon Dam is missing, too.
I emailed the map's maintainer about the omissions and he said he'll look into it.
Have you seen it lately? The Colorado River barely even reaches it anymore. The reservoir is like 300 feet lower than it was designed to run at.
As of July 2023 production is down 35%, but its definitely still operating and producing significant amounts of power.

Hoover Dam is on the Arizona/Nevada border, not in Washington.
