If you are talking about that big puddle just after the bridge when you leave the staging area with bathrooms then no, not really an easier way around.
There is a lot more accessible camping if you go down the mclean creek road towards millarville and pull off into one of those sites.
Otherwise, the only real easy way into the area you are talking about is if they open the gate on the gasplant road that leads to the gravel pit. Which I doubt they will do on the long weekend.
I dont know how to google those cordinates, but am guessing that is were you are talking about.
