earlier ice-outs
Earlier ice outs could also easily be attributed to more development around these lakes. More impermeable surfaces within a half-mile of the lakes results in warmer warm-water runoff into the lakes. Removal of shade trees surrounding the lakes, increased use of circulators for docks, solar reflectivity of surrounding structures, etc., all could be contributors. Yes, that's man-made impact, but does not support the governments money grab for pollution tax.
