Lower Albany - looking for more information, maps, shuttles, planes

I am looking for informatiuon re the Lower Albany.

the only  info i found sofar is a trip report from  1983

So far i learned to drive to Hearst, somehow do a shuttle/ bus ride to Cochrane.but don't feel comfortable leaving my gear just sitting around is not really an option in 2022
 

then over the kamikami river to Mammamattawa to the lower albany  to Fort albany

how is the lower Albany, flat, white water? 

i read that the airport in Fort Albany  is before you hit the delta of the Albany river - which could be confusiing

then I need info how to get from Fort Albany, to Moosomee, back to Cochrane or Hearst.
