2. About Barrage de Bani Walki

A Brief Overview

Name: Barrage de Bani Walki
Type: Dam (earth‑fill/rock‑fill) 🏗️
Location: Tanout, Zinder, Niger (NE)
Coordinates: 14.746295 N, 9.054233 E
Height & Altitude: Not publicly documented

The dam is listed on the German‑language Wikipedia page for the Bani‑Walki‑Talsperre (see the source for more technical details). While the exact dimensions remain undisclosed, the reservoir created by the dam is a crucial water source for the surrounding agricultural lands.

Historical Context

Construction of the Barrage de Bani Walki dates back to a period when Niger’s government, together with international development partners, prioritized water security for the Sahelian region. The dam was built to capture seasonal rainfall, mitigate the effects of drought, and provide a reliable water supply for irrigation in the Tanout area. Over the years, the reservoir has become a lifeline for local farmers, supporting crops such as millet, sorghum, and beans—staples of Nigerien cuisine.

Why It Matters

Water Management: In a country where annual rainfall averages less than 600 mm, every drop counts. The dam helps regulate water flow, reducing the risk of flash floods during the short rainy season.
Agricultural Support: By storing water, the reservoir enables year‑round irrigation, improving food security for the region.
Community Hub: The dam’s surroundings have become a gathering spot for locals, especially during the early morning and late afternoon when families come to collect water or simply enjoy the cool breezes.
