Winter pool cover for heavy snow?

I've been using a layer of ice (thick enough to walk on) as a pool cover successfully for years now. The downside is a more difficult spring opening. Leaf soup, pine needles, turkey feathers and turkey poop (86 of them use my trees as a winter roost) and to top it off, someone in my area uses rodent poison and a bunch of them find their way to my pool looking for water before they die in it (yay!). I clean and sanitize it to crystal clear every spring (thanks, TFP!) but the dead rodents put my wife over the edge and she wants a pool cover.

The problem is that I can't see any cover surviving my winters. I get an average of 103" of snow each winter. I typically don't see the ground from November to April. I have to assume there will be 4+ feet of dense compressed snow on top of the cover at some point. I also have to drain the pool by at least 2 feet in the fall or snowmelt will fill it back up before the last freeze. Come spring I've never had to fill the pool more than 6". One year I had to cut a hole in the ice to drain it before it reached my skimmer. So any sort of float will have to handle a significant water level change.

With this amount of snow, checking on the pool and addressing things throughout the winter is very difficult. I pretty much have to take every winterization precaution I can in the fall and say "Good luck! See you in spring" (Like, literally. It's buried in snow all winter). So far that approach has worked well for everything, but I can't see a pool cover surviving this winter gauntlet.

Does anyone have any winter cover ideas or suggestions that might work here?

For context, two pics. A typical summer and a typical winter.
You can't see it in the pic, but there are stairs down from the deck to the concrete two feet below. They're buried every winter.

My Meyco solid cover has held over 3 feet of snow some winters. Going on 25 years of service.

Well, your wife wants a cover, so a cover it will be.
My Meyco cover is now going on 15 yrs. I do as you - lower the pool to below the returns, and blow out everything. I put a couple of gallons of RV/Pool antifreeze in each line. All returns plugged on the pool side. The deep drain is airlocked. "Gizmos" (compressible plugs) in the skimmers to prevent water getting in the lines. 103" of snow is somewhere between 3" and 10" of melt water (very temp dependent when it does snow). I can get about the same amount as you. So extremely rare you have to worry about overflowing the banks. If the skimmer pipes are plugged, not much risk there either even if the skimmer pots do fill up - although some advise packing them with even more compressible things to give ice something to squeeze without damaging the expensive parts).
Now that the kids are gone, I may not need the cover for safety - but before the ice is thick enough, and there is snow on it, the dogs might be able to break through - so the cover still goes on. Dog claws have no impact on it, although I avoid tossing a ball in that direction.
It will sag some due to snow weight, but the springs on it are pretty industrial, so no issues there. Yes, the elephant pics on it are true - it can support a lot of weight. I am kind of a Clydesdale myself, and it supports me, although I avoid walking on it...
It is permeable, so melting snow/rain goes directly in the pool. And any fine junk that makes it through the fabric. So all the leaves/feathers/dead bodies stay out. The poop still likely will get through. As does dirt mixed in the snow. I can find worms in mine in the spring - I assume they crawl under the edges during rainstorms before freezing.
Heavy, and is a two person job to put on. Now that I am pretty old, I hurt a lot after with all the bending/stooping/etc. needed to raise the anchors and attach the springs.
The only thing that has ever hurt it has been some red squirrels that chewed on in when in storage in nicer weather. Cost me $250 just this year to repair the holes, and have all the padded parts restitched. With now better storage, I expect another couple of decades out of it.
 
That same ice rink you get now will support the snow on top of the cover. It will then insulate the ice below so it's the last part to melt in the spring.
 
I uncover at the same time as the ice goes out on the local lakes. Usually still a big ice cube floating in the pool, but haven't been so early that the cover is still frozen to it. Equipment startup is a few weeks later, after it is more comfortable out, and I am past freezing weather risk. A gallon or two of liquid Cl into the water every week or two, until it warms into the low 50's, then I get more serious about maintaining FC.

Ah, you're the person I'm looking for! You described my closing procedure exactly. From the Gizmos, plugs, airlocks, antifreeze, everything.

Yes, having to drain mid-winter is rare. The same year I had to do that the mountains in the background got 903" of snow. Yes, just over 75 feet. It was crazy. I'm not so concerned about the turkey poop getting through. My wife just sees it as "dirt" and it's very fibrous and easily filters out. It's just the animal carcasses for her and I'd be happy to keep the 4-5" ponderosa pine needles out which are just a PIA to deal with.

So the Meyco cover will survive it, huh? I assume you're talking about the RuggedMesh version, right? Seems like letting snowmelt drain through will be critical.
 
Back when, there was only one choice, but yes, mine seems to be what they call "Rugged Mesh". Before I cut them down, it did just fine keeping out the White Pine needles that dropped every fall (25 55 gal garbage bags hauled out of the yard every year!). About the same as your ponderosa pine needles.

The only maintenance, beyond the repair - pulling it off in the spring, and going over the surface with a scrub brush on a pole, and some lightly soaped warm water, and rinse with a hose, to get bird poop off. Flip and repeat. Dries pretty fast, so roll it up and put away until fall.
The screw type anchors can get grit in them over the years, so always good to unscrew all the way, and try to get any accumulation out of the threads before screwing them down for the summer. Too much, and they can bind and be a pain to unscrew. Getting a second long allen key, cutting off the short leg, and chucking into an impact driver (set on very mild) is a boon to quick unscrewing with less bending over or crawling around fooling with the anchors.

No need to cut down an Allen key. The stem of an impact gun bit, chucked into a regular drill backwards, fits the brass anchor.
