Cameroon Reservoir Transparency

No publicly accessible portal for current reservoir storage volumes. ENEO publishes occasional press releases during flood season mentioning specific figures (e.g. Lagdo at 213.46 m / 91% filled) but these are narrative communications, not structured data. MINEE's website lists no downloadable water-level datasets. Annual PDF reports exist (2017–2024) but contain generation statistics, not reservoir storage time series. No live dashboard has been identified for any of the four major storage reservoirs (Lagdo, Mapé, Mbakaou, Bamendjin).

No REST API, no open-format dataset (CSV, JSON, XML), and no data portal identified for any Cameroon reservoir. ENEO annual reports are PDFs locked in binary encoding. MINEE's site offers legislative texts and news only. The Lake Chad Information System (lis.cblt.org) covers the region but requires login and does not specifically expose Cameroon reservoir storage. No registration-free structured data source found.

Capacity-weighted (v1.3.0): ~1,225/15,300 Mm³ ≈ 8% (Lagdo 7,600 + Mbakaou + cascade reservoirs; only fragmentary ENEO press releases tied to flood-season events — no structured data feed, and the Sanaga cascade plus Lom Pangar have no public reporting at all). Prior justification (preserved for context): Denominator (RTI methodology): reservoirs with capacity >10 hm³. Cameroon has approximately 15–20 reservoirs above this threshold, dominated by the Benue (Lagdo ~7,600 Mm³) and the Sanaga regulating reservoirs (Mbakaou ~2,600 Mm³, Mapé ~3,300 Mm³, Bamendjin ~1,800 Mm³), plus Lom Pangar (~6,000 Mm³, commissioned 2017), Memve'ele, Mekin and smaller impoundments. Only Lagdo receives event-driven press releases from ENEO during flood season (typically August–October); no other reservoir has any public reporting. Effective sustained coverage is 0/~17; episodic coverage limited to 1/~17 (~6%). Score reflects the absence of any standing public data feed across the entire qualifying reservoir set.

No machine-readable historical time series is publicly downloadable. Academic research cites hydrometric records going back to 1945 for the Sanaga and Benue basins, but these originate from MINEE/ENEO internal archives accessible only through formal research agreements, not open platforms. No multi-year reservoir storage dataset (even static) has been identified for public download.

Data reaches the public only through ad-hoc press releases tied to flood-season events (typically August–October) or power rationing crises. No regular publication schedule exists. In 2023 and 2024 ENEO issued seasonal communiqués about Lagdo releases, but these are reactive communications, not a systematic update cycle. Annual PDF reports aggregate generation statistics with a 6–12 month lag.

ENEO operates a network of 13 hydrometeorological and hydrometric stations around Lagdo (densified from 6 in recent years), including gauge stations at Poli and Madingring and rainfall stations at Tama, Gop, and Baikwa. The 2023 PMC research paper on Songloulou mentions piezometric and pendulum measurement instruments. However, no public methodology document, measurement protocol, sensor calibration standard, or data quality report is accessible on any official website. Information sharing with Nigeria was characterised by NIHSA as relying on 'informal interpersonal relationships' rather than documented protocols.

Cameroon is constitutionally bilingual (French and English). ENEO's website (eneocameroon.cm) is fully bilingual and press releases are published in both languages. MINEE also maintains an English version of its website. Where reservoir data does appear in public communications, it is accessible in English. This is a genuine structural advantage relative to most sub-Saharan African countries; the bilingualism bonus is tempered by the near-total absence of substantive data to make bilingual.
