Green algae
« on: 07/18/11, 07:51 »
Huge pathces of green algae in Western Basin.  Seems like it's alot earlier than previous years.
Last year in September, it was horrible.  Seemed like 2-3 inches of the stuff, and definetly the blue-green species was present in large collections.  What's the plan from the scientific end??

With the huge inputs of water that we had this past March-May, it seemed inevitable that there would be an abundance of the freshwater algae limiting nutrient, phosphorus, which would trigger a huge algae bloom.

But turbulent spring weather has until recently kept the lake rather turbid, reducing sunlight penetration.
This delayed most early, widespread algae blooms. With the recent period of little rain or wind, the lake has cleared up dramatically and is now allowing light penetration to stimulate algae production.

I saw blooms of blue-green algae along the central basin coastline at Ashtubula (7/4) and Geneva (7/9), and by looking at the satellite images, it appears that Maumee Bay, Sandusky Bay, Catawba-Marblehead and places in-between are firing up algae blooms. This time of year, odds are that they are blue-green species, which do best in warmer water.

There was a report released in June from Lake Erie phosphorus researchers that listed their thoughts on some of the causes and solutions of phosphorus loading and can be viewed at  go.osu.edu/phosphorus

FYI, I had similar word of cyanobacteria/blue-green algae blooms regarding the far west waters of the lake, off the shore of Michigan, from the remote sensing programs of NOAA yesterday as well.

I observed B/G blooms offshore of Lorain on Sunday, July 17 while perch fishing about 2 miles offshore.  Started appearing around 10 AM and by noon the surface was a green sheen.  Warm, sunny and no wind made for perfect conditions.

I think Ohio's plan is to allow more water to be removed from Lake Erie, thus reducing the area that can produce algae. And, hope that someone else solves the problem.

PS fished in algae as thick as pea soup Friday WNW of West Sister. As a relic who remembers the horrible days of Erie algae I get sick to my stomach thinking that our pols are welling to gamble with one of our biggest assets yet again. Our short-sighted greed has to change some day, doesn't it?
