Following the hot weather, canals in London are now covered with a thick green layer of weed.
Work is being carried out to stop it damaging the eco-system.
Our Environment Correspondent Tom Edwards reports.
Any showers will soon die out this evening so that many of us will see a muggy, but dry and mostly clear night, with the odd misty patch forming in prone areas such as the Lea Valley.

An unemployed man has admitted raping an elderly woman after barging into her south London home.
The woman, in her 70s, was making breakfast when Jason Batchelor of Maldon Road, Wallington, attacked her in her house in Purley on 11 May.
The 46-year-old told police he had "messed up" when he was arrested.
He was convicted at Croydon Crown Court of rape, attempted rape, sexual assault, actual bodily harm and intent to commit a sexual offence.
The child, known as Baby R, died from head injuries inflicted by his father in January 2015. He was convicted of murder in December.
After his death, it transpired that his mother was a convicted murderer.
She had served nine years of a 12-year jail sentence in her country but fled to the UK while on parole.
It was revealed she was subject of an European Arrest Warrant.
The baby, who cannot be named, died in Haringey - the same north London borough at the centre of the Baby P scandal where a mother and her boyfriend were jailed for causing or allowing his death.
Tim Minchin is worried.
He may be a successful comedian, actor and composer, but he says he "just feels sick all the time" ahead of the world premiere of his new musical Groundhog Day.
Croydon’s medical services were dealt a double whammy this morning, when it was announced that the two bodies which run the area’s hospitals and GP practices, Croydon Health Services NHS Trust and Croydon Clinical Commissioning Group, had both been placed in financial special measures.
It claims leaving the European Union (EU) poses a "serious risk" to its research funding.
The hospital said it could also lose EU staff and long-standing EU partnerships.
But a leading cancer specialist said the hospital was being "hysterical".
Angus Dalgleish, professor of oncology at St George's, University of London, who also represents Brexit movement Scientists for Britain, told the BBC the claims by Great Ormond Street were a "gross overreaction and rather hysterical".
A campaign to raise money to rebuild one of the capital's lost outdoor pools has reached its first fund-raising target.
The organisers have raised more than £60,000 to launch a feasibility study.
Eleven people, including a 14-year-old boy and a 15-year-old girl, have been arrested following a "disturbance" in Ladbroke Grove, west London, early this morning.
The nine males, aged between 20 and 14, and two females, aged 15 and 18,were arrested for suspicion of violent disorder charges and some for possession of an offensive weapon.
Detective Inspector Driss Hayoukane, from Kensington and Chelsea, said: "Local officers responded quickly to reports of a disturbance and this resulted in 11 people being arrested.
"It's our duty to ensure our streets are safe and we will not tolerate any form of disorder within the borough.
"Enquires are ongoing into the disturbance last night. We have extra officers on duty across the borough tonight and throughout the weekend to provide reassurance."
At this stage the Met says there is nothing to suggest this incident is linked to the disorder across London on 19 July, notably a water fight in Hyde Park which turned violent.

A family court judge's behind-closed-doors ruling which relates to the murder of six-year-old Ellie Butler should be made public, the Court of Appeal has decided.
A three strong panel - headed by Lord Dyson, the Master of the Rolls and the head of civil justice in England and Wales - analysed issues surrounding publication of the ruling at a hearing in London earlier.
The ruling was made by Mrs Justice Eleanor King following a behind-closed-doors hearing in the Family Division of the High Court in the summer of 2014 - after Ellie had died but before her father Ben had been convicted of her murder.
Another family court judge had decided Mrs Justice King's ruling should not be published in case reporting prejudices any re-trial.
Mrs Justice Pauffley, who is also based in the Family Division of the High Court, last month rejected an application from several media organisations who argued publication of Mrs Justice King's ruling would be in the public interest in the wake of Butler's conviction.
But appeal judges have now overruled Mrs Justice Pauffley and said Mrs Justice King's ruling should be published.
Ben Butler, 36, inflicted catastrophic head injuries upon Ellie while looking after her at their home in Sutton, south-west London, in October 2013.

Mr Khan admitted he could not play the guitar as he posed with the instrument and three of the four members of the band on the steps of the National Gallery in Trafalgar Square.
He was also joined by rapper Tinchy Stryder and singer Jessie Ware as he insisted the vote to leave the European Union will not mean London will be closed to talent and creativity.
He said: "London is open. We have to send a message that we are open to business and talent and investment and trade.
"I was concerned the impression was given post-Brexit that London is closed off, but London is open.

Mayor of London Sadiq Khan has told Newsbeat building the city's nightlife culture is a "core priority".
In response to claims regulation of UK clubs is "a problem" [link to main piece] he said: "Too often, these venues find themselves under threat from new development and red tape."

Losing EU funding for medical research could cost the lives of some vulnerable children, Great Ormond Street Hospital (GOSH) has said.
In a plea to the Government to secure a deal with Europe that protects research and enables the hospital to "retain its brightest minds", GOSH said there is a "serious risk" it could lose EU staff, funding and long-standing EU partnerships.
Since 2010, GOSH, in central London, has received £25 million from the EU - 10% of its funding - for research into new treatments and cures.
With its research partner, the UCL Institute of Child Health (ICH), GOSH is the UK's only academic biomedical research centre specialising in paediatrics.
GOSH said 44 EU-funded research projects are active, with six at clinical trial stage for new treatments.
Fourteen research projects are under review, with "uncertainty about current grants, or applications in the future", it said.
They include a man caught on CCTV who appears to be aiming a missile at police officers.
The images have been added to a gallery of suspects sought in connection with the disorder which saw a water fight descend into violence.
