The editorial test
Each item must add evidence, a useful method, guidance or a regulatory change. We show the water accounting boundary, the evidence or legal status, and the practical question it helps answer.
Publication date and archive date are separate. A daily check may add nothing when there is no substantive development.Items in the archive
Browse separately by evidence category, then refine by water topic or search.

Entries are prepared through a daily research scan of public sources. Read the linked originals before relying on a finding. Regulatory status is checked when an item is added and may later change; the source link is the authority. Scientific studies distinguish preprints from peer review and modelled from measured findings; laws distinguish proposals from legally effective requirements. Status is a dated snapshot, not live legal advice. The ledger is independent analysis, not legal or engineering advice.
