Action has been taken to increase the oxygen levels in a Swindon lake after large numbers of fish died.

Oxygen levels crashed in Queen's Park Lake in August because of the "unprecedented hot and dry weather".

A new aerator has been installed in the lake thanks to- officers from South Swindon Parish Council and an aquatic management specialist.

The aerator turns over 165,000 litres of water every hour to oxygenate the lake. 

Further plans for the lake are scheduled including the removal of duckweed and vegetation.

The parish council say silt reduction treatment has also been planned.

Some residents had thought that the rise in duckweed on the lake was linked to the deaths.

But the parish council has confirmed this is not the case, saying: "Although this problem is unsightly and not the ideal environment for wildlife it is not the reason for the sudden deaths of large numbers of fish stock within the lake."

The low oxygen problems occurred because of the minimal rainfall over the last few months.

Queen’s Park Lake is spring fed from Old Town and, when the water levels decreased, more silt and organic matter was dragged up.

This increased the nutrients in the water which led to the oxygen crash.
