KalaWewa Dam Overflowing Part 1 - 28 Nov 2025 (Raw Footage) | Cyclone Ditwah/Rainy Season Sri Lanka

On 28 November 2025 — during the heavy rainfall and flooding brought by Cyclone Ditwah — I visited Kala Wewa to capture raw, unedited footage of the reservoir overflowing its spillway.

About Kala Wewa:
Kala Wewa is an ancient twin-reservoir system (Kala Wewa & Balalu Wewa), originally built by King Dhatusena in the 5th century CE, with a storage capacity of around 123 million m³ of water.A 40-feet-wide central sluice supplies water to thousands of acres of paddy fields, channeling water over 87 km via the historic canal Yoda Ela (also called “Jaya Ganga”).

What you’ll see in this video:

The enormous volume of water bursting through the spillway — a powerful reminder of the intensity of the rains and floodwaters.

The sheer scale and structure of the reservoir and dam — a living piece of Sri Lanka’s ancient hydraulic-engineering heritage.

Unfiltered, real-time visuals: no editing, no music — just raw nature and the reality of flood conditions during this storm season.

Why this matters:

Provides documentary-style evidence of how historic infrastructure behaves under extreme weather, in light of climate change and heavy monsoon / cyclone-induced rainfall.

Offers viewers (locals, Sri Lankans abroad, and global audience) a look at one of Sri Lanka’s ancient water reservoirs under stress — showing both beauty and power.

Serves as a visual archive: floods like these may become more frequent; documenting them helps raise awareness about water management, heritage preservation, and climate-resilience.

⚠️ Disclaimer / Note:
This is raw, unedited footage. Viewers may see turbulent floodwater, strong currents, and possibly unstable ground — please watch responsibly. The video is not meant to sensationalise danger but to document real conditions.
