Sierra Leone 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: No machine-readable or systematically published reservoir storage data found. The GVWC website (gumavalley.sl) exists but publishes no dam level bulletins or storage figures. The Bumbuna HPP (50 MW run-of-river) is operated by EDSA with no public hydrological reporting. Sporadic press releases from GVWC mention water shortages but do not provide storage percentages or volume 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: No API, bulk download, or structured data format available. GVWC and NWRMA (National Water Resources Management Agency) maintain rudimentary websites. NWRMA publishes maps of river basin gauging networks but no downloadable datasets. Data infrastructure is minimal.

Capacity-weighted (v1.3.0): 0/13 Mm³ = 0% (Guma Valley dam serving Freetown; GVWC publishes no operational storage data). Prior justification (preserved for context): Methodology denominator counts reservoirs with capacity >10 hm³. Sierra Leone has approximately 1 qualifying reservoir: Guma Valley Dam (~13 Mm³, just above the threshold), supplying Freetown. Bumbuna HPP is run-of-river with negligible storage; Babadorie is under rehabilitation and well below threshold. Guma Valley has no public storage data published by GVWC. 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: No historical reservoir storage time series identified. Civil war (1991–2002) destroyed institutional records and interrupted hydrological monitoring. Post-conflict reconstruction has focused on physical rehabilitation rather than data systems. No multi-year dataset for Guma Dam or Bumbuna is publicly accessible.

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: No regular data publication identified. GVWC does not publish weekly or monthly storage bulletins. The Ministry of Water Resources and Sanitation publishes policy documents but not operational hydrological data. Any reservoir information reaching the public is ad hoc via press releases.

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: No public methodology documentation for reservoir measurement. The National WASH Sector Development Plan 2025–2035 discusses building a web-based knowledge and sector data system, indicating awareness of the gap. The World Bank-funded Water Security and WASH Access Improvement Project (2025) includes capacity building for water data management, but these systems are not yet operational.

English is Sierra Leone's official and sole administrative language, which gives it full accessibility for international users without translation barriers. All government websites, GVWC publications, and World Bank project documents are in English. The language score is moderated because the underlying content is too sparse to fully benefit from the linguistic advantage.
