    This location shows yesterday's ice cover with '16 & '15. If you want to move around the site you can locate over years coverage. Currently the 5% is near historic lows for this date. Should look a lot different in 10 days or so.

    Very cool comparison. The lack of Saginaw bay ice is interesting.

    It's the new normal boys, we need to just get used to it. We can only hope for an 'old school' winter once or twice per decade anymore (like 12'/13 and 13'/14'), but most years, we're going to have open water and frequent winter thaws. The Grand Traverse Bay ice cover records are really telling, (that data set goes way back) and it what is used by U of M climate scientists.

    Why is the average so straight and the other line so jagged?

    The straight red dotted line is the Long-Term average of 55%, the maximum ice coverage over the past 40+ years. The black dots that are connected are the actual maximum coverage for individual years. This year is going to be 1 of the 5 lowest over the past 44 years.

    Thanks. It looks like ice coverage on the great lakes is quite variable, at least in the last 44 years. Maybe with less ice there will be more photosynthesis and better fishing for me and everyone else in the summer! That's my bright side point of view.

    I would think there would be more nitrogen in the water too, but I don't know if that's related to anything or even true for that matter.

    Less snow and lack of cold winters hurts the river systems that feed our lake nutrients and do not rehydrate the aquafers. So when it's late September and the river is at all time lows and too warm that's why. Gotta have snow pack..... long winters and ice cover to help our long term health of lakes. Warm winters are good once in a while to kick start the delicate fishery we have but long term the natural reproduction of cold water fish will struggle.
