Why do canals not flood?

Canals are a lower flood risk than rivers as the water flow to them is controlled via reservoirs rather than them being fed by rivers and streams.

Do canals flood in heavy rain?

Thanks to their proximity to rivers, our canals are prone to flooding in extreme weather conditions. In most cases when a canal floods we will close the stretch of waterway to the public and wait for the water to subside naturally.

Are canals dirty?

Is Canal Water Dirty And Dangerous? Although the water in canals may sometimes look muddy it is actually usually fairly unpolluted. Unlike rivers, canals do not carry industrial waste or drainage away from cities.

Leakage often starts on a small scale, but the moment that water has found a way through a canal embankment a hole will develop through which water will leak.
