The Lom Pangar Dam is a hydro‑electric and water‑storage infrastructure on the Lom River in the Adamawa Region of Cameroon. It creates the Lom Pangar Reservoir, which is among the largest artificial lakes in the country.
Location and geography
The dam is situated near the town of Garoua, approximately 300 km northeast of Cameroon’s capital, Yaoundé. The Lom River is a tributary of the Sanaga River, the largest river system in Cameroon, and the dam lies within the transitional zone between the Sahelian and forested regions of the country.
Design and construction
The structure is a rock‑fill dam with an auxiliary concrete face, designed to withstand the seasonal fluctuations of the Lom River. Construction of the dam was undertaken by a consortium of international and local engineering firms under the Lom Pangar Project. Financial support for the project was provided by the World Bank, the African Development Bank, and the Government of Cameroon. The dam’s construction commenced in the early 2010s and was completed in 2017, after which the reservoir began to fill.
Purpose and operation
The primary objectives of the Lom Pangar Dam are:
- Flow regulation – The reservoir moderates the discharge of the Lom River, ensuring a more consistent flow for downstream hydro‑electric facilities on the Sanaga River, notably the 138 MW Sanaga‑II project.
- Hydropower generation – The dam houses a small hydro‑electric plant with an installed capacity reported to be around 15 MW, providing electricity to the surrounding region.
- Water supply – The reservoir serves as a source of drinking water for the city of Garoua and supports irrigation for agricultural activities in the basin.
Environmental and social impact
The creation of the Lom Pangar Reservoir resulted in the inundation of approximately 300 km² of forest and savanna, leading to the displacement of several hundred residents and the relocation of local communities. Environmental impact assessments, conducted as part of the project’s development, identified concerns regarding biodiversity loss, alterations to fish migration patterns, and changes in downstream water quality. Mitigation measures—including resettlement programs, reforestation initiatives, and fish‑pass facilities—were incorporated into the project design, though evaluations of their effectiveness continue to be monitored.
Current status
Since its commissioning, the dam has been operational, contributing to Cameroon’s objectives for renewable energy expansion and improved water security. Ongoing monitoring focuses on reservoir water levels, power output, and the long‑term ecological effects within the basin.
