A worried mother said that it was necessary to "do something" after his son was almost dead when he fell into a channel that he confused with grass – just a half an hour before a father and his son make the same mistake.
His teenage son was returning home after a meal at Nando's in Walsall, in the West Midlands, when he collapsed in the cold channel, currently plagued by grass.
The 19-year-old did not know how to swim and could only keep his head out of the water until he was pulled by a passer-by.
His mother, who lives in Darlaston and wishes to remain anonymous, said it was "horrible to think about what could have happened" and that her son was now traumatized.
She told Birmingham Live: "It could happen to everyone, something needs to be done – or are they waiting for someone to fall and die." I thank God that he came up with him. help from friends and a passerby.
"I thought he was joking when he told me that, it made him such a shock, it all left us shocked by what happened."
The mother of two said that her son was soaked when he returned home. He had visited the nearby Premier Inn, where the hotel staff kindly provided towels so that it could dry a little.
The same evening, Steve Worthington and his 11 year old son, Lewis, plunged straight into the water.
The 41-year-old had to fight to keep his boy's head above the water as he tried desperately to flee.
We just came in and went straight under the water, "he said.
"We have never been there and we have not seen any warning signs in place. The whole area is composed of green and thick weeds – it looks like grass.
"The water was freezing and me and we had to go several times, it was so scary. We had to fight for about five minutes. "
Mr. Worthington stated that he had since had nightmares since the dive and that his young boy was now mentally scared.
A spokesperson for Canal & River Trust, who oversees the waterway near the site, said: "We are aware that there is a problem of weed proliferation in the basin, which may give the impression that the area is covered with thick grass, hiding the water below.
"Safety signs have been installed on the pond to warn people of the danger. Weed control is a permanent battle and a team of Canal & River Trust will be deployed in the pond to eliminate sections of the weed in the next few days. "
But Rebecca Whitehouse of Charity warned that weeds would probably be back soon. She added, "This weed is a ferocious plant, and as soon as we clean it, it grows back in a few days, and it creates not only a danger, but people and pets get lost thinking that it is also very expensive. to remove ".
