(Apply "Occam's Razor" to their problem nearby).

3) No recent breezes to dilute blooms, so hot surface waters are quietly "cooking the broth".

4) The lake's level has been kept artificially high, causing waves (but especially wakes) to reach deeper into the sub-soils which have sequestered tons of phosphorus and nitrogen.

5) Pine-tree pollen, which slows the normal mixing and dilution of Spring's lakefront waters is occurring presently--as normal.

6) A hot seasonal weather pattern which encourages biological growth is upon us and likely to put a synergistic action into this mess.

7) This is not to mention the sandbar problem.

Great post APS! I agree with this 100% except for #7. I don't think people swimming (or peeing!) at sandbars has anything to do with algae blooms. #1 through #6 are spot on in my humble opinion however...

I see a lot of people on facebook are mis-identifying cyanobacteria as pollen. Pollen is all over the top of the lake (all lakes) right now and is nothing to worry about as it happens every year at this time...
