I suppose
the "rare," record-setting escalating water temperature tracked by the National Weather Service and
reported by the Journal Sentinel means more stinky algae growth along the shorelines, but can anglers tell me the impact on the fisheries?
Low Record Heat has Warmed Lake Michigan
The
unseasonably warm weather of the past week along with the warm spring
temperatures have contributed to Lake Michigan surface
temperatures warming into the upper 60s to upper 70s. The below image
was taken Friday morning, July 6th, by the MODIS instrument package
on polar-orbiting satellite Terra or Aqua. Most of southern Lake
Michigan had warmed into the 70s as indicated by the orange color.
In contrast, below is the MODIS image taken one year
ago, on July 6th, 2011. Surface temperatures were about 5 to 10 degrees
cooler, mostly in the low to mid 60s.
The graph below shows this year's average lake
temperature compared to the previous five years. As you can see, this
year is about four degrees warmer than the average lake temperature of
the past five years.
In fact, the south mid lake buoy reached 80 degrees on
Friday, July 6th. This is rather rare, as in the 31 years of data, a
temperature of 80 degrees has only been recorded during six prior
episodes. This is also the earliest 80 degrees has ever been recorded at
the south mid lake buoy.*
It is also worth noting that during the past warm period between, July 1st and July 6th, the water temperature rose 10 degrees!*
Furthermore, the average water temperature at that
particular buoy on July 6th is 63 degrees, while the average temperature
record on July 6, 2012 was a whopping 78 degrees.*
In inland lkes - fish go deeper and in the fall there is something called turnover when the cold water reverses with the warm water causing a complete shutdown of fishing. Not sure about LM. Usally, warmer weather causes less activity in fish. A strong pressure system coming in may result in increased activity in fish and more bites. The stagnant system we see here may be causing fish to shut down. It's hard to catch fish on really still and warm weather. But what do I know, this is the big pond.
ReplyDeleteUnseasonably warm weather????
ReplyDeletein the summer????
What season would you expect warm weather????
Do you understand the meaning of "unseasonable", Anon@4:44?
ReplyDeleteIf you do, why are you feigning incomprehension?
If you don't, well there's no cure for stupid.
