Will the bucket sink? No. But, what happens when you try to pick that bucket up out the water? Huge amount of weight. So, if your waders fill up you need to strip down, then re-enter your yak. 56º water can get you hypothermia quicker than you think. That being said, waders with a dry top would be fine. I rarely wear my waders, but when i do it's mid-winter and night time. I layer for the cold, but should invest in a dry top.
