THE Environment Agency stepped in to halt fish deaths in a Spalding drain after salt levels rose to toxic levels.
Ongoing drought conditions caused salt levels to rise in South Holland Main Drain and this was lowered with fresh water pumped in from the River Welland.
The Environment Agency acted following reports of dead fish floating on the surface.
Environment management team leader Manfai Tang said: “We are continuing to monitor the situation and expect it to improve with fresh water entering the drain.
“It is important for people to tell us if they spot distressed fish so that we can take action quickly.
“The new fishing season is now under way and we are asking anglers and other river users to help us keep an eye on our waterways.”
Fresh water was pumped from the Welland by South Holland Internal Drainage Board.
Holbeach and District Angling Club has been kept updated and supported the action to save the fish.
* Anyone who sees distressed fish – gasping at the surface or trapped in shallow pools – is asked to contact the Environment Agency hotline on 0800 80 70 60.
