Lowes Lake carry to the oswegatchie

so im taking a group of 8 students on a 3 night backpacking/canoe trip the first week in june (yes i know its bug season!!) this year and we have our sights set on the ever elusive oswegatchie headwaters trail/carry that goes from lowes lake to the oswegatchie river.... we are putting in at lowes dam about 9:30 am and hope to travel all the way to campsite 34 which appears to be the closest campsite to the carry.... i cant find any information or pictures on this site and i am concerned about space for the group of 9 total.... anyone out there camped here or been here to scout it out? how about the virgin timber landing i see you can camp there with a special permit should we consider this.... anything you guys know would be very helpful!!!!!
