Fiji Reservoir Transparency

Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: No current reservoir storage volume (Mm³ or % fill) is published online by any Fijian government authority. Energy Fiji Limited (EFL) discloses Monasavu dam levels only through ad-hoc press releases — typically qualitative or in metres above sea level (e.g. safety level 725 m asl, critical level 715 m asl) — not as structured open data. The Fiji Meteorological and Hydrological Services (FMS) publishes monthly Monasavu Outlooks at met.gov.fj, but these are rainfall and temperature forecasts for hydroelectric planning, not current storage readings. The FMS River Level page offers an interactive map but covers river gauging stations, not reservoir storage. EFL annual reports submitted to parliament (parliament.gov.fj) report generation in GWh but omit reservoir volume data. No national body publishes a systematic reservoir-level dataset.

Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: No API exists for any Fijian reservoir or dam dataset. The FMS Monasavu Outlooks are distributed exclusively as downloadable PDF files — not as CSV, JSON, or any other machine-readable format. Historical climate and hydrological data from FMS requires submission of a paper Data Request Form by email (climate@met.gov.fj), with no guaranteed format or turnaround time specified. The Fiji Bureau of Statistics data portal (data.statsfiji.gov.fj, launched June 2025 with SPC support) offers API access to statistical datasets but contains no reservoir or dam data. No registration-free, open-format download path exists for any reservoir variable.

Methodology v1.3.0 (capacity-weighted), conservative. Fiji has approximately 91 hm³ of qualifying national reservoir storage capacity, dominated by Monasavu (~91 hm³ on the Nanuku River, 80 MW); Nadarivatu is run-of-river with negligible storage. Energy Fiji Limited discloses Monasavu levels only reactively during droughts (citing altimetric thresholds at 715/725/731 m asl) and FMS publishes monthly Monasavu Outlooks that are rainfall/temperature forecasts rather than observed storage. Conservatively, effective covered capacity through reactive crisis disclosures is approximately 7 hm³ of qualitative signal on Monasavu. Coverage = round(100 × 7 / 91) ≈ 8.

Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: No machine-readable historical reservoir storage dataset is publicly accessible. The Fiji Division of Hydrology has maintained internal records of dam capacity and stream discharge since at least 2009 (Monasavu storage level at 723 m asl at the start of 2009 appears in a government report), but these records are not published online. FMS data requests may yield historical hydrological series, but this is subject to approval, unspecified fees, and manual processing — it does not constitute open accessible historical data. EFL annual reports to parliament contain generation GWh figures going back several years but no volumetric reservoir data. The SPC Pacific HYCOS project (2006–2010) established some river monitoring infrastructure in Fiji; its final report (2010) is publicly archived but contains hydrograph data for rivers, not reservoir storage timeseries.

Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: The FMS Monasavu Outlooks are published monthly (the most recent series as of May 2026 covers November 2025–June 2026), making this the only regular public data product with any connection to Monasavu conditions. However, these outlooks are rainfall and temperature forecasts, not observed reservoir readings. EFL issues dam-level statements through press conferences only when water stress warrants public conservation appeals — typically a few times per year during drought events, with no fixed schedule. No automatic or near-real-time publication of storage levels exists. The regulatory environment (Fiji Commerce Commission) does not require periodic public disclosure of operational reservoir data.

Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: No published documentation describes how dam levels are measured at Monasavu or Nadarivatu — instrument type, gauge datum, frequency of readings, or quality-control protocols are not disclosed. The only publicly known reference points are the safety level (725 m asl) and critical level (715 m asl) for Monasavu, cited by EFL's CEO in a 2023 press conference. The FMS publishes monthly Monasavu Outlooks but does not describe the hydrological model, input station network, or validation methodology. A World Bank EIA (2007) for the Nadarivatu scheme contains a hydrological assessment with some methodology, but this refers to project appraisal-era studies, not current operational monitoring practice. The Fiji Division of Hydrology tracks 'surface water, stream discharges, rate, volume, dam capacity, and rainfall' per government reports, but no corresponding methodology document is publicly available.

English is one of Fiji's three official languages and is the primary language of government, business, and all EFL and FMS communications. Every official document found — EFL annual reports, FMS Monasavu Outlooks, government fact sheets, regulatory reviews — is published exclusively in English. International users face no language barrier when navigating the official sources. The score is not perfect because the overall information ecosystem is sparse; English accessibility provides no practical advantage when data is not published at all.
