Data Availability
20% of total score
No current storage volume or water level data for any Ivorian reservoir is publicly accessible online. CI-ENERGIES publishes aggregate electricity production statistics (GWh totals by source) but no per-dam hydrological indicators. CIE's website lists fixed technical specifications for Soubré (reservoir volume 83 Mm³, lake area 17.3 km²) but these are static construction-era figures, not current readings. The national open data portal data.gouv.ci lists 26 energy datasets, none of which cover reservoir storage, water levels, or hydrological monitoring. No bulletin hydrologique, no dashboard, and no downloadable time-series exist from any official Ivorian source.
Technical Accessibility
15% of total score
No API, no open data format, and no machine-readable reservoir dataset exists from any official Ivorian source. CI-ENERGIES and CIE websites are corporate communications platforms in HTML only. The national portal data.gouv.ci is publicly accessible without registration but contains no water-resources or hydrological datasets. The DGRE has a Facebook page and no functional web portal for data access. Satellite-based remote sensing (Google Earth Engine, Sentinel) is being used by researchers precisely because no official machine-readable data is available.
Coverage
30% of total score
Capacity-weighted (v1.3.0): 0/38,000 Mm³ = 0% (Kossou 27,700 + Buyo 8,900 + Taabo + Ayamé; CI-ENERGIES and SODECI publish no operational reservoir data). Prior justification (preserved for context): Denominator (RTI methodology): reservoirs with capacity >10 hm³. Côte d'Ivoire has approximately 10–12 reservoirs above this threshold: Kossou (~27,700 Mm³, one of Africa's five largest artificial lakes), Buyo (~8,900 Mm³), Taabo (~625 Mm³), Soubré (~83 Mm³), Ayamé I (~970 Mm³), Ayamé II (~190 Mm³), Faé/Singrobo (under commissioning), plus drinking-water impoundments around Abidjan (Adzopé, Mbahiakro). Zero of these have publicly accessible storage data — CI-ENERGIES, CIE, and DGRE all publish nothing operational. Coverage rate is 0/~11 = 0%. Score reflects total absence of any public reservoir-storage publication despite the country hosting one of Africa's largest artificial lakes by capacity.
Historical Depth
13% of total score
Historical hydrological records for Kossou exist within the academic and operational sphere — peer-reviewed studies cite discharge, inflow, and water level records spanning 1972–2022 at Kossou, and 2016–2022 satellite-derived water surface data for Kossou and Buyo — but none of this data is publicly downloadable from an official Ivorian portal. The GRDC holds some Bandama river discharge data, but this is not reservoir storage data and access is through a German federal agency. No official Ivorian institution publishes a machine-readable historical archive of dam storage.
Update Frequency
10% of total score
No regular publication schedule for reservoir data exists from any official source. CI-ENERGIES publishes its annual electricity statistics report (e.g., the 2022 Rapport Développement Durable) and occasional financial statements, but these contain no hydrological monitoring data. There is no weekly, monthly, or seasonal bulletin on dam levels or storage volumes comparable to those published by France (Eaufrance BSH), Morocco, or South Africa. Any reservoir status updates are internal operational data, not public.
Methodological Transparency
8% of total score
No public documentation of measurement methods, sensor networks, or data quality standards for reservoir monitoring has been located from any Ivorian state institution. Academic studies (2024) note that in-situ monitoring relies on a single ground station for the major reservoirs, and that this ground-truth data is provided to researchers by CIE under non-disclosed terms, not published openly. The new Water Code adopted in November 2023 and the PASEA project's 30-station deployment suggest that methodological frameworks are being developed, but as of the 2026 evaluation date these are not published or operational.
Language and Usability
5% of total score
All official communications from CIE, CI-ENERGIES, DGRE, and the hydraulics ministry are exclusively in French, consistent with the country's official language. CI-ENERGIES publishes one bilingual (French/English) version of its annual electricity statistics, but this document contains only aggregate GWh production totals with no reservoir data. Since no reservoir data is accessible at all, the question of English availability is largely moot, but partial credit is awarded for the bilingual electricity statistics publication and the general accessibility of the data.gouv.ci portal interface.
Evaluator notes
Côte d'Ivoire hosts one of Africa's most significant hydroelectric cascades — the Bandama system (Kossou 27,700 Mm³, Taabo, Soubré) and the Sassandra system (Buyo 8,900 Mm³, Soubré 83 Mm³) — yet achieves a near-zero RTI score across all dimensions. The country presents a paradox: massive physical water infrastructure with essentially no public data infrastructure to match. CIE operates six hydropower plants under a concession from the state but publishes no operational hydrological data; CI-ENERGIES reports only aggregate electricity generation; the DGRE maintains a social media presence but no functional data portal; and data.gouv.ci's 26 energy datasets are exclusively electricity subscriber counts and rural electrification plans, with no water resources content. The gap between physical and informational infrastructure is confirmed by multiple independent sources. A 2024 peer-reviewed study (Jofack Sokeng et al., Remote Sensing in Ecology and Conservation) used satellite imagery and Google Earth Engine specifically because in-situ data from CIE was limited to a single ground station and not publicly accessible. UNEP's interactive country fiche explicitly flags a 'lack of reliable and relevant information on the country's water resources, particularly in terms of functional hydrometric networks.' The $825M World Bank PASEA project (2024) is deploying 30 new telemetric hydrological stations — infrastructure that would not be needed if monitoring already existed. Two large-scale international programmes signal near-term improvement: the EU's WASUNA programme (€310M, 2024) is rehabilitating all six major hydroelectric dams, and PASEA is building hydrometric station networks. Côte d'Ivoire adopted a new Water Code in November 2023. However, as of September 2026, no public-facing reservoir data portal or bulletin has emerged from these investments. Researchers, planners, and the public remain unable to access current or historical storage volumes for any Ivorian reservoir through official channels.
