ALL Sharon and Ian McFarland could do was watch as floodwaters swallowed their backyard, pontoon and boat.
The Loganholme residents, whose property backs onto the Logan River, held their breath as water surpassed 2011 flood peaks.
"We don't know where our boat is," Mrs McFarland said last Tuesday.
"We're just hoping it's still attached to the pontoon."
The McFarland's, who have lived at Loganholme for seven years said they had survived four previous floods but nothing quite like the latest deluge.
"There was one in 2008, 2010, 2011 and 2012 but nothing as bad as this," Mrs McFarland said.
"Fortunately are boat is insured but our pontoon isn't and costs $40,000."
Next door, the McFarland's neighbour's pontoon was saved by a group of three men who dubbed themselves the River Rescue Team.
Mitchell Gardner, Brendon Huwes and Danny Cloughley used their tinny to reach pontoons and tie them to safety.
"We do it because we're nice people," Mr Cloughley said.
"We're getting a lot of gratitude."
Logan Mayor Pam Parker is calling on more good Samaritans to don gumboots and gloves and support each other in the clean-up of flood-affected properties throughout the city.
Cr Parker said the coordination of a "mud army" would go a long way to getting the lives of flood-affected residents back to normal as quickly as possible.
