This year vs the years that matter
This year's trace against the finished years this gauge has published. Its public daily record begins in 2020, so the driest and wettest years are not named yet: that takes 8 finished years, and the lake regulars will remember wetter and drier years than any line here.

Full pool, datum, and the gauge
"Full pool" here means the conservation pool — the level the lake is designed to hold for water supply and recreation, not the flood-control space above it. The full explainer covers flood pool and dead pool too.
