Toxins have been ruled out as the death of seagulls discovered in a town centre lake.
As reported, people were shocked after discovering the dead seagulls on a algae-hit lake in Weymouth - prompting authorities to investigate.
The gulls were found in the Swannery area of Radipole Lake where a green film is covering the water near Westham Bridge.

During hot weather algae blooms form on top of the water - which can be toxic and harmful to animals.
It has now been revealed that the algae bloom on top of the lake is not toxic following an investigation from Dorset Council.
A spokesperson for Dorset Council said: “The UK Centre for Ecology and Hydrology has determined that the bloom isn’t harmful blue-green algae.
"The Environment Agency has also visited the site and taken samples – we are currently waiting to hear back on the results."
The council has also confirmed it will be working to clear the water surface 'soon' as in previous summers the Environment Agency has discovered blue-green algae at the lake.

The spokesperson added: “It should be noted that this bloom is a natural occurrence, and there has already been a significant reduction in algae levels in the area, most likely due to recent heavy rainfall.
"Our contractors have been instructed to clear the weed and detritus, and we should have a start date for the works soon.”
A wildlife rescuer has claimed that the deaths of these seagulls is likely from food poisoning or starvation.
Derek Davey, 65, has been rescuing gulls for more than 25 years, and he says that the hot weather means that the birds have to scavenge more for food.

He said: "When there is hot weather, the gulls have to scavenge more for their food, as we have over fished the seas.
"They scavenge for food left by people, like burgers, and basically they get food poisoning and it is lethal to them as not many can survive it.
"It is one of the reasons, but for younger gulls, it is starvation as there is not enough food for them.
Mr Davey added: "It's a real shame.
"The whole way gulls are treated is disgusting, like they are vermin, but we should be able to live with them.
"It happens every year with the hot weather and it will happen again."
