Dozens of people have expressed an interest in helping to shape the future of a West Norfolk beauty spot, according to its owners.
But, on the eve of the school summer holidays, officials have renewed their appeals for people to stay out of the waters at the Bawsey pits site.
The new plea has been issued almost exactly a year on from the deaths of 41-year-old Ryan Pettingell and Umar Balogun, who was 16, who drowned in the lakes.
Gary Stringer, resources director of Sibelco, which owns the former sand extraction site, said: “Working quarries should be no-go areas for anyone not connected with the business and even those areas where work has stopped are potentially dangerous.
“The water can be much deeper and colder than people expect with sudden shelves and hidden weed.
“Please stay out of the water this summer. We really do not want anyone having to endure the heartache of losing someone they love.”
Last month, the company held a public meeting to unveil the results of its public consultation on the future of the site and set up a working group to draw up development ideas.
Mr Stringer said the firm had been amazed by the scale of interest, which saw around 600 people take part.
And around 70 people have so far indicated that they want to join the group.
Mr Stringer said: “We intend to invite them to a meeting after the school holidays and ask them to begin drawing up proposals.
“By the new year we hope to have a clear idea of how Bawsey can be taken forward and that vision will be presented to the public for further feedback.”
