The Department of the Interior's money, the whole of it, traced to the source.

Office of Budget · U.S. Department of the Interior

Every Interior bureau — the National Park Service, Bureau of Land Management, Fish & Wildlife, the Geological Survey, Reclamation, Indian Affairs and the rest — read two ways: by bureau and by appropriation account. FY2025 actuals, FY2026 enacted, and the FY2027 request. The net discretionary appropriation is kept strictly separate from the energy and mineral leasing receipts Interior collects on the Federal estate, and from its mandatory / permanent authority — and reconciles to the published department topline via the Budget in Brief's own A-18 chain. Every number recomputes against its own source.
