Hundreds of fish have been killed in a park lake after a significant decline in oxygen levels due to an increase in water temperature.
Residents saw the fish floating on the surface of the lake in Locke Park, Redkar, Teside.
The Environment Agency (EA) investigated and determined that it was caused by “natural factors”.
Labor MP Anna Turley said it was “troubled to see such distressed scenes” in a popular green place.
EA said that it has not found any evidence of pollution in Jalkund.
“We have investigated a fish incident in Locke Park and determined that it was caused by natural factors,” said a spokesman.
“Long -term dry weather, low or stable water flow and increased oxygen levels with increased water temperature led to a significant decline, resulting in fish mortality.”
Council leader Alek Brown said that walking around the lake was “serious”, which had all the fish floating in the water.
The Labor Counselor said, “When I was eight years old, I caught my first fish in the park.”
“It was absolutely terrible to see 300 to 400 fish in the lake and it became very bad.”
Turley said she was “deeply worried” with the report of fish dying.
He said: “It is a very liked green place in the heart of Redkar, and it is upset to see such distressed scenes.
“I am grateful to the council for quick and immediately investigating the immediate reason.”
