Granbury.
Follow everything.

Lake Granbury is our local microscope: trace the water, power, heat, money and records on the same timeline. The point is not to start with a villain or a conclusion. The point is to make every material claim auditable.

The rule: proximity is not pumping. Authorization is not use. Gross withdrawal is not net consumption. Contract capacity is not actual load. Correlation is not causation.

~53.2% of the 2024 gross-intake proxy occurred June–September: ~1,271 AF of ~2,389 AF.

The monthly bars are a schematic visualization of seasonality, not monthly measured quantities. The June–September aggregate and annual proxy are CALCULATED from the documented operating dataset.

Design capacity, average physical intake, cooling share and annual BRA customer ledger values describe different boundaries and must not be substituted for one another.

Flood release is not total release. Local watershed inflow is material. These ledger terms should be evaluated with storage change and routing rather than treated as independent impacts.
