Weather weirding

My lake near Lake Minnetonka of about 140 acres in size and with 8 feet of average depth went ice out on March 7th. Wind speeds were at least 30 mph for a sustained time. My lake is now ice in. I do not recall this happening in the past 2 decades. I typically see 2 regime changes per year. Looks like will have double that amount for 2017. I’d say the high winds forced a regime swap removing lake insulation. The lake wanted its ice back and got it.

I’ve also seen another rare occurrence. Typically the creek/ditch outletting to Lake Minnetonka stops doing that before and during Winter. The creek is dry. It will flow all Winter this year as it did a year ago. Back to back occurrences means what? There has not been unusually high levels of precipitation. Call our recent Winters milder. Cold decreases water flow. With global warming, farmland may drain more in Winter. The farmers can get into the fields earlier. They may need less tile. There may be less Spring Flooding in Fargo. Perhaps it’s the case that a sped up hydrological cycle is better.
