About Represa Tonkoli

What Is It?

• Type: Dam (🏗️)
• Location: Colomi, Cochabamba, Bolivia
• Coordinates: -17.336109, -65.911387
• Height: 3.5 m

The dam is officially catalogued as MMAyA CB‑P‑014, a reference used by local water management authorities. Though modest in size, Represa Tonkoli plays a functional role in the region’s irrigation network, helping small farms and livestock operations manage water flow during the dry season.

A Brief History

While there is no extensive historical record or Wikipedia page dedicated to Tonkoli, the dam’s construction aligns with Bolivia’s mid‑20th‑century push to improve rural water infrastructure. Small concrete dams like Tonkoli were built to harness seasonal streams, providing reliable water for agriculture in the high‑land valleys surrounding Cochabamba.

Why It Matters

• Community Lifeline: The dam supplies water to nearby villages, supporting crops such as potatoes, quinoa, and beans.
• Ecological Spot: The reservoir attracts local bird species and serves as a micro‑habitat for amphibians and insects.
• Cultural Landscape: The dam’s presence reflects the blend of traditional farming practices and modern engineering that characterizes much of rural Bolivia.

How to Get There

From Cochabamba City

1. Start in Cochabamba: Head north on Ruta 7 (Carretera a Colomi). The drive to the town of Colomi takes roughly 45–60 minutes (≈ 60 km) depending on traffic.
2. Turn onto the Local Road: After passing the main square of Colomi, look for a small, unpaved road signposted “Represa Tonkoli.” The turn is about 5 km after the town center.
3. Final Stretch: The last 2 km are a gravel lane that winds through farmland and pine‑grove patches. Keep an eye out for a modest concrete wall and a small parking area on the right—this is the dam.
