Snodgrass also put forward a phenomenal ride to not only claim an outright podium with second, but also comfortably score the 251cc-450cc 4-Stroke class win over eight minutes clear of his closest rival.
"Today was a crazy one with all that rain coming down, making it a really tough mud race in the desert, so to finish second outright and first in class was definitely awesome," Snodgrass said.
"The Prologue was important and we did well in that, so today I tried to have the cleanest race possible all the way through to the end - it was a matter of survival in those conditions by the time we got to the last lap and especially towards the end. The KTM 450 EXC-F was faultless all weekend and we managed to get one position better than last year, so I'm rapt with that result."
Yamaha's Josh Green rounded out the podium ahead of Lachlan Terry and Mason Semmens.
After e blistering start, 2018 winner Daniel Sanders was on his way to what looked like a repeat win until prevalent water caused a suspected problem with the electrics, forcing him to stop and fix the issue. Despite losing around 20 minutes, he went on to claim 14th position outright and seventh in the Over 450cc 4-Stroke category.
"It's very disappointing because the team and I put a lot of effort into this one event each year," Sanders said. "Obviously the weather today played a part and we started strongly, but unfortunately, the issue meant we gave away the win because I felt as though the race was mine at that point. The track was full of puddles because of the rain falling and we were hitting them at high-speed, so that could have led to the problem. We ended up getting going again and I brought it home to the finish, but it wasn't to be today."
