It's not often fishing is as easy as dropping a line into the water right outside your suburban home.

But when Stirling resident Jillian Intini spotted a school of fish swimming in a puddle, she and her husband Mino knew they had to grab their chance.

"We were just walking the dog as we do and we could see all these carp swimming by in the puddle, so we thought why not? and rushed home to get our fishing gear," she said.

The lake at Princeton Estate near where Mrs Intini lives is home to plenty of carp - an invasive species - and the high water level from the rains that lashed Perth overnight meant the fish were able to roam much wider, even splashing around under the play equipment.
