Cummings lives on the dairy farm with her husband Jock, who has a full-time job in Gore.
She milks a herd of 235 predominately Holstein Friesian cows, under the stud name Mayalan Holsteins.
Helen praised the way neighbours and the Southland community worked together in the days following the disaster.
"We had 23 friends and family turn up on the Saturday following the flood to help with the clean-up and 26 people on the Sunday. It was truly humbling," she said.
"Plus, there were several members of the Farmy Army - a volunteer group organised by Federated Farmers - and a team from the Gore A&P Society, where Jock is president."
"Extra silage was also given to us to help us get through while we didn't have much grass for the cows to eat," she said.
It's likely the effects of the flood will be felt into next season.
The flood destroyed three hectares of crop, which would have been used to feed half the herd during Southland's icy winter.
"Bits of the crop have regrown. We've undersown it with rape, which is another brassica. So, we will have feed, but the tonnage per hectare will be down significantly."
"We've had to keep the in-calf heifers out at grazing longer instead of bringing them home."
