Cardiff Bay Barrage is a significant engineering project located in Cardiff, Wales. Completed in 1999, the barrage was built to create a freshwater lake in Cardiff Bay by damming the River Taff and the River Ely. This project transformed the bay area, which was previously a tidal estuary, into a more controlled water environment.

Key Features and Purpose:
Tidal Control: The barrage helps manage tidal flows, preventing flooding and allowing for the creation of a stable freshwater environment.

Recreation and Tourism: The area around the barrage has been developed for recreational use, including walking and cycling paths, boating, and various leisure activities. It has become a popular destination for both locals and tourists.

Environmental Impact: The construction of the barrage altered the local ecosystem. While it created new habitats in the freshwater lake, it also raised concerns about the impact on marine life in the estuary.

Hydropower Generation: The barrage includes a small power station that harnesses tidal energy, contributing to renewable energy production.

Economic Development: The project played a crucial role in the regeneration of Cardiff Bay, leading to significant investment and development in the area, including residential, commercial, and cultural projects.

The Cardiff Bay Barrage is often noted for its engineering complexity and its role in transforming the landscape and economy of Cardiff.

Good place for a stroll or poodle on the bike. Decent section of the Bay cycle path for younger riders.

The Barrage connects Penarth to the Cardiff peninsula. It offers stunning views across the sea to one side, and the freshwater bay on the other. One of the highlights of the Cardiff Bay tour
