Ugh. That's a tough one. Sometimes, if you can get a live person at the west gate, you can get some intel on where the crews are working. Of course, it can depend on the nature/scale of the work that needs to be done. I see Cedar is similarly delayed but a date has been suggested for re-opening. We are going into the NW corner of the Park May 1 and there are no issues. There does not appear to be any rhyme or reason to the lead time around when access may be permitted or announced beyond checking the Alerts page every morning. At this stage, and I'm sure you are, I would be looking at Plan B to make sure you'll get on the water May 1. I expect you will put in somewhere.. I hope you have a great trip, Joe.

Ya I'm going to the grand access and the road is also closed. I am not too optimistic that it will be open by this weekend with the monsoon we have coming. 

Rock Lake needing 4WD drive must be a seasonal thing. The road is a wide smooth (as can be for a dirt road) road. I have driven it in a Honda Fit many times. 

The Barron Canyon road, although the same type of road, can get nasty. There are some low parts (like just before the McManus road) that are at the same height as the surrounding swampy/ponds, and some big hills that get really chewed up this time of year. However, when its in good shape its fine. The drier the road is the better for sure, or when it is frozen. 

Scoutergriz, is that private road the one before you enter the park, where there is a cabin that appears to be on an island in the middle of a swamp on the north side of the road? Just before the "shooting range".

I see that, Fred!  Just getting some shuteye in Petawawa before heading in in the morning.  Gotta hand it to the park maintenance team - that’s a lot of roads and facilities to cover and they got a bunch of them clear.
