The poor ducks had gotten lost on an estate in the village of Allerton Bywater.
Six out of the seven ducklings had fallen down a grate and become stuck in the drains.
Officers were quick to act and pried the grate open.
They then put them in a box and took them to St Aidans Nature Reserve.
A spokesman for the West Yorkshire Police Leeds East team said: " Whilst out and about this morning local officers noticed a duck and it's duckling next to a grate in an estate in Allerton Bywater
"On closer inspection 6 out of the 7 ducklings had fallen down the grate into the drains.
"After 10 mins of getting the grate open and fishing them out we managed to get them in a box and to the nature reserve
"I can't remember that being in the application form
"It's not all about catching criminals".
They were praised for their efforts on social media by local residents, who were so happy to hear that the ducklings had been saved.
One user said: "Glad you've got all your ducks in a row. Sometimes Nature needs a helping hand and it was lovely of you to help out", while another added: "Aw lovely - thank you West Yorkshire Police."
Local non-profit group Garforth Hedgehogs said: "Good you could save the ducklings.
"Nice to know we have caring police officers in our area. Keep an eye out for hedgehogs too, they get themselves stuck in all sorts."
