What organization was this? Because I was in the US army in the 80s and by then we had maps that were created and marked as red light readable. I've never heard of the blue light filters so I'm curious.

Canadian Army, we were always short of funds and Canadian topo maps then and even today are generally 20 years out of date. In my civy job I tried to push for us to improve them to no avail. US mapping products are much better than ours. Up here most of the good mapping is under private copyright.

How did the blue light impact the water features on the map?
It helps to have a large budget. I'm surprised there isn't a relationship with Canada and the US that allows you to just buy maps from the US.
