tricky question.
no one can say its safe 100% anywhere. and everywere.
saw some place where they was like 24 inch off ice then goes to 3 inch ina few feet..cause off some high curent area or under water stream etc.
use to fish first ice years ago..at the cottage..and we just did some hole wit an axe to see,then we go fater down and do the same..and always 2 people and a rope then go farher abd farther then we were ok.
but we did no those waters.
its wen you go in a new area that could be tricky even worst wen you never been there even in soft water..becasue wen you been there in hot wetaer condition you have notice some streamsn going in or high curent or narrowing betwn two island where they could be more current and so on.
sometime goin in soft water in those area could help to find great spot for ice season..could find deaper hole wit the fish finder then puit them on your gps and go back there in winter.
the major pro on ice is snow...it covers the black sra where you could see better wehere it could be good or no good.
been in some place i taught it was great until i hit like 2 time wit an axe and went true..

..meening like 1.5 inch...and you are 250 pound plus the sled full at 75 pound let say you feel a lot smaller then..

.
but like said you never no.é..you see a lot off time big ice fishing derbies there is like few hundres car on the ice..but one guy did went true..in one area..why...currents///streams//deaper hole//tons off factors.
the worst enneymies on ice is snow...but it could become a good friend wen its melt and become more ice.
nitle anecdote in 1998..i was going for a derbies in hull on the ottawa river..a full weekend one...so we deside to go the night before to see where we could place are tent the next morning at 6am..it was like 8pm then..so we go down on ice wit my pick up drive around in bay(gatineau boom)..and so on found a place go back out.
the next morning we go back.....what we saw its like..

...
a guy wen on ice wit is pick up...and WENT TRUE THE ICE...BUT IN MY TRACK......

..my track i did like 9h before wit my truck..so that made me think wow..i could have went true that ice at 8pm pitch black outside what could have happen to us in the truck we dont no...all this to say..we never no what can happen.
did went true in a creek wit some cross country ons..that right cross country ski..imagine i was like 16 then..i was in a creek alone..lac des fees gatineau park area...man i did got so scre and the only reason i am here now..its because there was only 4 feet deap..beasue i could not go back on mu skie were hiting the ice under so it tookme like a good 10 min to go back on..soaking wet and have like a 2km walk to go back home...those moment make you think.
some dont think mutch and take chance ..sometime one to manny...and i am guilty off this to.....
those is it worth it..realy......... to take a chance in an area we dont no for some crappies or pike or walleye or wathever the species..its just a freaking little fish..and you are ready to die and let your famillly get all that trobe for freaking tiny fish... that are not even good to eat for are health.
ok i got my ideal out...hahaha
be safe and enjoy ice fishing.safely.
but again its personal...all ahve there choice mine now is do something helse until its safer...snowshoeing and crooscountry ski and so on.
and wen the time comes i will do my time on ice.
