Now, after decades of resistance, even dishwasher soap must meet higher biodegradable standards, so soap would be a very unlikely cause of foam in this lake.
The "test" is to scoop up the suds and smell them. I've never detected soap odor, even before any Phosphorus standards came into being.
Perhaps it was in the old forum, but I'd written of Langmuir Streaks before; however, Google doesn't return
Langmuir Streaks—but
Langmuir Circulation.
(News to me).

In especially strong winds, I've counted as many as 11 parallel streaks off our particular shoreline. By October, the foam can appear in long cylindrical clumps—much like beige-colored swim noodles.
