Suoi Hai Lake

Suoi Hai Lake is a large artificial freshwater reservoir at the foot of the Ba Vi range, created primarily for irrigation, environmental regulation and downstream water management, with an important secondary landscape and tourism role.

Ba Vi foothills, western Ha Noi
Overview

Understand the place through its setting, meaning and everyday use.

Ha Noi sources describe Suoi Hai as a man-made reservoir fed principally by the Yen Cu and Cau Rong streams from the Ba Vi mountains. Official publications are inconsistent about some numerical attributes, including storage capacity and one article's apparent area typo; this profile therefore uses only the robust identity and function facts and treats mutable or conflicting measurements cautiously.

Key things to understand

  • See the broad water-and-mountain relationship.
  • Understand the lake first as working water infrastructure.
  • Use established roads and authorized recreation areas.
  • Treat island counts and capacity figures cautiously when sources conflict.
  • Check weather and local water-management restrictions before waterside activities.

Questions

Frequently asked questions

Is Suoi Hai a natural lake?

No. Ha Noi sources describe it as an artificial freshwater reservoir built for irrigation and environmental/water-management purposes.

What feeds the reservoir?

Official cultural information identifies Yen Cu and Cau Rong as the two principal streams associated with its formation.

How large is it?

A Ha Noi source gives about 10 km² of water surface, but other published numerical details conflict, so this profile avoids unnecessary false precision.
