Stoddard was 12th, equal with Japan's Nozumi Komura, after two days of racing at the event.
It represents a solid improvement from last year, when she was 17th in Altenberg, Germany.
Stoddard placed eighth, 16th, 13th and 11th in the four individual heats in Lake Placid, and was one of 10 riders to break the track record.
Her push-start has been much stronger this season and she had the third fastest push of the whole competition, Stoddard told the Otago Daily Times in an email.
She said weather fluctuations had affected racing.
In training, it had been as cold as -15degC but the temperature was about zero on the first day of competition and got as warm as 7degC on the second run.
"The ice conditions were extremely variable and choice of equipment for the race was critical," she said.
"I got caught out since I had gone with runners which are better suited to much colder conditions. Overall, given the equipment disadvantage I feel satisfied that I performed well."
Stoddard said her main aim was to have four consistent runs, as that will be the format of skeleton racing at the Winter Olympics in Vancouver next year.
New Zealand men's skeleton racers Iain Roberts and Michael Coutts were placed 20th and 28th respectively before their event was postponed because of deteriorating track conditions.
The 2008-09 season has been Stoddard's most successful.
She achieved five top-12 finishes in nine races on the tough World Cup circuit and finished with rankings of 13th (World Cup) and 16th (overall).
Stoddard was 12th at the world championships and won an America's Cup event in Calgary.
Her season is effectively over apart from two final America's Cup races in April.
