As previously reported, torrential rain over New Year caused the canal to burst for the first time in more than 50 years.
Bridgewater Canal, which runs through Lymm, completely gave way on one side a short distance away near to neighbouring Dunham Massey.
Canal water levels are reported to be dropping in Grappenhall due to the breach near Lymm, with the water looking more brown than usual.
Cllr Graham Gowland, Liberal Democrat councillor for Lymm South, was one of those to visit residents on Sunday, as well as Tatton Conservative MP Esther McVey and others.
Cllr Gowland said: “We took away an action plan for immediate support needs and will progress this over the next few days. Immediately, everyone is safe, which is great.
“In the meantime, please keep away from the boats by Ye Old No 3. If you plan on going to see the breach, the towpath runs on the north side of the canal, and you cannot see the breach from this side.
“I understand access is probably not safe on either side, but it impacts the boaters less if you go on the north bank. There are ‘footpath closed’ signs on both sides.”
Cllr Gowland added: “The canal breach is a ‘once in a lifetime’ incident, and it is quite understandable that people want to have a look at the devastation.
“I notice people have been walking down to the breach. Obviously, there can be danger from further collapses.
“The people who live on the boats at the moorings by Ye Old No 3 have had their lives turned upside down, and I would ask that you please respect their situation and do not take photos of their homes.
“For clarity, I am not saying do not go and see the breach – that is up to you.
“I am simply letting you know there are a number of people impacted who feel that taking pictures of their homes is distressing, and the breach is not visible from these boats.”
Local politicians including Cllr Graham Gowland and MP Esther McVey spoke to residents
Lymm Heritage Centre has also explained what the breach of the canal could mean for Lymm.
The canal last burst in 1971, when it was closed for two years for repairs which cost £250,000.
The heritage centre said: “The latest breach of the Bridgewater Canal is a tragedy for the canal, its users, and in many ways for the whole of Lymm itself.
“Lymm Historic Transport Day has annually highlighted its importance, and throughout the year it is a popular stopping point for boaters on the Cheshire Ring, or for shorter journeys to and from Manchester.
“The potential downside for Lymm is clear. Fewer boats mean fewer visitors.
“We can only hope that Peel, the ultimate owners via the Bridgewater Canal Company, working in conjunction with Bridgewater Canal Trust, can respond more positively and quickly than last time round in 1971.”
