Dimension breakdown
Data Availability
20% of total score
APUA issues ad-hoc press releases with Potworks Reservoir staff-gauge readings (e.g. 12 ft in Oct 2025, 6 ft 11 in in Apr 2025) but there is no structured dataset, open portal, or systematic publication schedule. Data is embedded in media announcements, not downloadable files.
Technical Accessibility
15% of total score
No machine-readable format, no API, no downloadable time-series. Information is accessible only via HTML press releases on apua.ag or third-party news aggregators. SCADA infrastructure is being planned but has not yet produced any public-facing data layer.
Coverage
30% of total score
Capacity-weighted (v1.3.0): ~2.25/9 Mm³ ≈ 25% (Potworks dam dominates the national denominator; APUA publishes only ad-hoc press notices during drought — no structured feed, partial signal credit only). Prior justification (preserved for context): Potworks Dam (~9 Mm³ capacity) is the sole significant surface impoundment in the country. APUA announcements address this single reservoir, but coverage is episodic rather than systematic, and Barbuda's water infrastructure (desalination-based) is not covered.
Historical Depth
13% of total score
No publicly archived time-series is available. Scattered news records go back several years but readings are not compiled into any retrievable historical dataset. The earliest publicly citable gauge reading found dates to 2025.
Update Frequency
10% of total score
Updates are reactive — triggered by drought emergencies or media inquiries — rather than published on a fixed schedule. During the 2024–2025 drought, announcements appeared roughly monthly, but long gaps occur in normal conditions.
Methodological Transparency
8% of total score
Press releases cite staff-gauge feet readings but provide no documentation of measurement protocol, datum, accuracy, or conversion methodology to volumetric storage. No formal monitoring standard is published.
Language and Usability
5% of total score
All APUA communications are in English, the country's sole official language. The website and associated news releases are fully English-language and reasonably navigable by international users.
Evaluator notes
Antigua and Barbuda has exactly one significant surface reservoir — Potworks Dam on Antigua — with a capacity of approximately 9 Mm³ (one billion US gallons). The Antigua Public Utilities Authority (APUA) monitors reservoir levels and issues periodic press releases with staff-gauge readings, particularly during drought episodes. This constitutes a form of public disclosure, but it falls well short of structured data transparency: there is no open portal, no downloadable time-series, and no machine-readable format. The country's growing reliance on desalination and rainwater harvesting further reduces the centrality of reservoir monitoring to the national water supply equation. The RTI score therefore reflects partial, reactive disclosure of a single small impoundment. APUA has announced plans to deploy SCADA infrastructure that could, in future, support real-time public monitoring. Until that happens the country sits in the lowest tier for technical accessibility and methodological transparency, with modest credit for the fact that ad-hoc English-language announcements are at least publicly issued.
