River Brenig

[citation needed] The Brenig meets the River Teifi just below Tregaron.

[1]: 21 Between 2008 and 2010, a £2.7m development project by Environment Agency Wales began in Tregaron to protect the town from the river flooding.

This involved lowering the riverbed and building floodgates, as well as implementing improvements to existing floodwalls.

Brown trout are prevalent in the river and larger specimens can be caught in the narrower parts where the water runs deeper.

[citation needed] Prior to 1840, sections of the river were canalised to safeguard a local turnpike road.
