that 224 may be the accumulation total year-to-date. as mentioned check with the Department of Transportation or forest service for the areas you're looking to go into they can give you better updated info about a week before you go. it doesn't take too many warm days to melt it off pretty quick. if you're fishing the only thing you really have to watch for is that water is going to be damn cold and if the levels are high don't fall in. be sure to take warm clothing jackets, goid shoes/boots etc... because the weather changes and you want to be prepared.
I always pack my Sorels even in the summer, I've been up fishing and got caught in freak snow and hail storms and temperature drops to less than 40 so always glad to have warm boots and a warm coat
