A "significant number" of dead fish have been found in a waterway in Boston, the Environment Agency has said.

The agency found low oxygen levels and ammonia in the Maud Foster drain.

Several fish species including roach, common bream, pike, perch and tench were found dead or in distress.

Officers used chemical aeration to raise oxygen levels and took samples for testing.

Since the initial report on Wednesday, the agency said there had been no further deterioration to the water quality.

Ammonia occurs naturally in rivers but it is also discharged into waterways from a range of different sources. High levels can kill or harm fish and other aquatic life.

The Environment Agency said its officers were maintaining vigilance at the site and would monitor the water.

A spokesperson said: “We are very grateful to members of the public that reported this incident. If you spot any fish in distress please report it to us.”
