Burundi Reservoir Transparency

Coverage is 0 (no national reservoirs >10 hm³ with public data). Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: IGEBU publishes weekly PDF bulletins on Lake Tanganyika water levels, freely accessible without registration on igebu.bi. However, Lake Tanganyika is a shared transboundary lake (Burundi, DRC, Tanzania, Zambia) and not a national reservoir. The two main national HPP reservoirs — Rwegura (10 MCM, 18 MW) and Mugere — have no publicly accessible current storage or water level data. REGIDESO, the operator, has its website in maintenance mode as of mid-2026. No dashboard, bulletin, or open file has been found for national reservoir storage volumes. The score reflects the existence of the Tanganyika bulletin but the complete absence of any data for the actual national reservoir infrastructure.

Coverage is 0 (no national reservoirs >10 hm³ with public data). Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: All published hydrological data from IGEBU is in static PDF format only. The Lake Tanganyika bulletins are downloadable PDFs (no CSV, JSON, or other machine-readable format). IGEBU references a WIS2box data exchange system (wis2.igebu.bi) for international meteorological data sharing, but this does not expose reservoir or lake level data via API. No REST API, SPARQL endpoint, or structured open format has been found for any Burundian reservoir or lake level data. The IGEBU data request section implies manual, non-automated access to datasets. REGIDESO's portal is down.

Capacity-weighted (v1.3.0): 0/~10 Mm³ = 0% (Rwegura dam dominates the small national denominator; REGIDESO publishes no operational reservoir data). Prior justification (preserved for context): Methodology denominator counts reservoirs with capacity >10 hm³. Burundi has at most 1 borderline qualifying reservoir: Rwegura (~10 Mm³, exactly at the threshold). Mugere is ~3 Mm³ and the ~26 micro/small HPPs are well below threshold. Lake Tanganyika is a natural transboundary lake, not a constructed reservoir. Rwegura has no public storage data: REGIDESO's website is in maintenance mode, and IGEBU does not cover hydropower reservoirs in its publications. Coverage = round(100 × 0 / 1) = 0.

Coverage is 0 (no national reservoirs >10 hm³ with public data). Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: IGEBU publishes an annual hydrological yearbook ('Annuaire hydrologique'); the most recent edition publicly available on igebu.bi covers 2020–2021, indicating a multi-year publication lag. The yearbook covers river flow stations and likely Lake Tanganyika levels, but not HPP reservoir storage. Third-party satellite platforms (Copernicus Hydroweb, G-REALM USDA) offer Lake Tanganyika altimetry records from 1992 to near-present, but these are not Burundian government publications. No machine-readable multi-year time series for national reservoirs exists in any accessible national portal. Score reflects the existence of yearbooks (albeit lagged and PDF-only) and the Tanganyika bulletin archive on igebu.bi back to at least 2024.

Coverage is 0 (no national reservoirs >10 hm³ with public data). Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: The Lake Tanganyika bulletin is published weekly by IGEBU during flood-risk periods and at reduced cadence in the dry season — the most recent found was dated 29 August–4 September 2025. This is a genuine regular publication cycle. However, for national HPP reservoirs (Rwegura, Mugere) there is no periodic data release at any frequency. The annual hydrological yearbook has a 3–4 year publication lag (2020–2021 edition is the latest public version). Score reflects the weekly Tanganyika bulletin partially offset by the complete absence of any update frequency for national reservoir data.

Coverage is 0 (no national reservoirs >10 hm³ with public data). Quality dimensions for the COVERED subset are therefore 0 by definition. Original notes preserved below: IGEBU's website describes its mandate (collection, analysis, processing and dissemination of hydrological information) and references a national network of hydrometeorological stations, but does not publish instrument specifications, gauge datum references, calibration protocols, or quality-control procedures for the Lake Tanganyika bulletins or the hydrological yearbooks. The HYCOS-IGEBU project (WMO-funded) equipped stations with automatic transmission to headquarters, but associated methodology documents are not publicly linked. No measurement or modelling methodology is published for HPP reservoir monitoring. The bulletins identify current water level readings but without traceability documentation.

IGEBU's website is available in four languages — French, English, Kinyarwanda, and Swahili — and the interface itself is navigable in English. However, all substantive data products (the Lake Tanganyika bulletin PDFs, the hydrological yearbook) are published exclusively in French. The Lake Tanganyika bulletin page lists archives going back to 2024 and the English site navigation is functional, which partially satisfies the usability criterion. Official languages are French and Kirundi; English is a working language in the region. Score reflects English UI accessibility but French-only data content.
