Her 128.35 time included a penalty touch and pushed her back to 26th overall.
Spain's Maialen Chourraut took out the final, ahead of local paddler Carole Bouzidi and Great Britain's Elizabeth Neave, but Jones was delighted with her consistency this season with her second Olympic campaign just over a month away.
"I've made both semifinals this season quite easily and I also know now that with a good semifinal run, I can definitely make the finals, which was less of a possibility in the past couple of years. It is great to be putting down fast times and making big improvements in the Olympic year and so far, it's been a good build-up toward the Games. It would be nice to lay down a good semifinal run and make the final at the next world cup in Spain next week."
Fellow Olympic-bound Kiwi Mike Dawson also made the semifinals with a slick 92.40sec second run putting him 19th but hit trouble in his semifinal and eventually finished 39th.
Frenchman Etienne Daille won the men's K1 final in 100.17secs, ahead of Jan Vondra (Czech Republic) and Austrian Lucien Delfour.
