USBR
USBR logoThe Bureau of Reclamation (USBR) designs, operates, and reports data for many western reservoirs—storage, deliveries, and published pool information tied to congressional authorizations.

Why it matters on the water
From Colorado River storage to Pacific Northwest irrigation projects, USBR sets seasonal targets, minimum pools, and flood space rules that show up as operating bands on charts. Boaters and irrigators both read the same published stage—often with project-specific datums and footages.

| Agency | Geography / role |
