Plans are being put forward to pump more than 2,000 tonnes of silt from a North Tyneside lake in an effort to rid it of algae.
In the past Tynemouth boating lake has been cleared using an environmentally friendly chemical treatment.
A new report suggests there is 2,000 tonnes of silt in the lake, which has accumulated over the last 60 years.
It says the silt contains the nutrients that feed the algal growth and recommends its removal.
North Tyneside council proposes to remove the silt using specialist-pumping equipment.
This will mean the lake will not need to be drained, helping to protect its eco-system, officers say.
The council is to invite contractors to tender for the specialist work.
Cllr Ed Hodson, cabinet member for the environment, said: "The council recognise that this has been an ongoing problem for the users of this facility for some time.
"We are delighted that we now have a long-term solution in place that could resolve the problem once and for all."
