Water Levels

[Yakfly]

Now that we can start thinking about wading the White again (maybe?) I am confused about the tailwater chart from the COE website.

Looking at todays report, it looks like generation of 38 - 50 MW caused a tailwater level of 453 feet. But I was always told that dead low tailwater was right at 450 feet, and that 45-50 MW generation was about 1 full unit, which would cause a tailwater rise of about 1 foot (not 3 feet).

I assume that the tailwater level is taken up close to the dam, so previous generation has a minimal effect.

Am I missing something here, or do I just need to forget about these COE charts?
