Dawson will join fellow New Zealand Olympian Luuka Jones at the event in the US, with both paddlers bringing in rare form as they enter the final year before trying to qualify for the Rio de Janeiro 2016 Games.
While Jones finished the World Cup season ranked eighth - with a season-best result of 10th in Slovenia in June - Dawson switched between slalom and the more lucrative extreme paddling, a combination he's used to fund his Olympic dreams for the last 10 years.
Earlier this month he had another decent boost, to both his bank balance and confidence, at the European extreme race championships in Lipno, Czech Republic, winning for the third time.
It was especially satisfying after recovering from wrist surgery earlier in the year.
"Extreme racing will take a bit of a backseat while I build up to the slalom worlds, but it's nice to know that my wrist can stand up to the pressures of racing in big water," said the Tauranga-raised kayaker.
It was the 27-year-old's second extreme win of the year, following his victory in the Great Falls Race in the US in July. He also finished third in the Ekstremsportveko (Extreme Sports Week) in Norway in late June.
He's also made plenty of headway in the Olympic slalom discipline, picking up his best World Cup result, an eighth placing in Slovenia.
Following the Great Falls win, Dawson spent a month slalom training at the Deep Creek site and has been back there for the last fortnight in an effort to familiarise himself with the unique course, which recirculates 550m over a manmade series of boulders. "The course is built at the top of the ski resort here and made using real rocks, as opposed to plastic rocks, so it's quite a good feeling to be paddling on a course that almost feels like a natural river.
"I'm loving paddling here - we are surrounded by some of the most amazing whitewater in the US, living at the edge of a lake and paddling on a ski resort - it's almost like we're in New Zealand.
"I was even able to escape the slalom scene last week and head off to paddle on the famous whitewater of Gauley River, a nice change from the slalom scene."
