Blue Green Algal Bloom

Whilst traversing the Leeds Liverpool canal we began to notice a green scum forming on the water surface. It started just above Langber Bridge and stretched almost all the way to Niffany Swing Bridge. Thats a distance of about seven miles. Said to be caused by a combination of the recent warm temperatures with intermittent bursts of heavy rain that is washing fertiliser into the canal.

We have reported this to the Environment Agency hotline on 0800 807060

The Environment Agency website reports that the Blue-green algae produces toxins which can harm, or even kill, farm animals, pets and wild animals, and cause skin-rashes, eye irritation, vomiting, diarrhoea, fever and muscle and joint pain in people. The Environment Agency reports a significant rise in the number of incidents that have been reported compared to recent years. Blue-green algae, or cyanobacteria, starves fresh water of oxygen. It is a significant risk to human and animal health. Ingestion can lead to symptoms including convulsions and liver failure.

There is a need to take more stringent precautions such as keeping ropes clear of the water. Plus making sure that pets don't enter or drink the water if passing through this area. We did notice warning signs in the Foulridge Tunnel to Bank Newton Locks area. But there is no notices on display here.
