The band is the lake's own normal: where the level has run on each calendar day, 1989–2026. The summer drawdown — and how this year sits in it — shows up without reading a single number.

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.
