Pegasus Lake at Moto Quay

Pegasus Lake is a man-made lake located in the Pegasus Township in North Canterbury.

This lake is prone to blooms of potentially toxic cyanobacteria ('blue-green algae') in the summer months (November to April) in particular. 

While recreational water quality monitoring usually shows very low numbers of E.coli  in summer (i.e. 'excellent' long-term status), the presence of potentially toxic cyanobacteria ('blue-green algae') can make the lake unsuitable for swimming.

If warnings signs are present at the lake, a warning is indicated on LAWA, scums of algae are visible at the water surface, or the water is cloudy or discoloured, people and animals should avoid all contact with the water and algal material.
