About Represa Mari Marini

What is it?

• Type: Dam (🏗️)
• Location: La Paz, La Paz Department, Bolivia
• Coordinates: -16.418312, -67.897103
• Height: 4.0 m

The dam’s official designation appears in engineering records as MMAyA LP‑G‑027, a reference code used by the local water authority. While there isn’t a dedicated Wikipedia page, the structure is recognized on regional maps and by the Ministry of Public Works, signaling its functional role in irrigation and water storage for nearby agricultural plots.

A Brief History

Represa Mari Marini was constructed as part of a series of small‑scale water projects aimed at supporting the high‑altitude valleys surrounding La Paz. These dams were built in the latter half of the 20th century to capture seasonal runoff from the surrounding Andes, ensuring a reliable water supply for both farming families and livestock. Though the exact year of completion is not publicly documented, the dam’s design reflects the pragmatic, community‑focused engineering typical of Bolivian rural infrastructure.

Why It Matters

• Water Security: The dam helps regulate water flow during the dry season, safeguarding crops that feed local markets in La Paz.
• Ecological Balance: By slowing runoff, it reduces soil erosion and creates a micro‑habitat for native amphibians, birds, and aquatic plants.
• Cultural Landscape: The dam sits amid traditional Aymara farming terraces, offering travelers a living snapshot of Andean agrarian life.
