A Teesside park closed because of fears about possible pollution has re-opened to the public.
Locke Park in Redcar was closed on 4 August as a precaution following the discovery of dead fish in the lake.
Redcar and Cleveland Council called in the Environment Agency, which carried out tests, and found no pollution.
It is thought that the recent hot weather caused oxygen levels to drop. A machine to re-oxygenate the water has now been installed at the lake.
The machine will remain in place until park staff are confident oxygen levels are back to normal, according to the council.
Notices advising visitors not to enter the water or to allow animals to drink from the lake have been removed and anglers have been allowed to return to the area.
