Most likely it is algae growth due to nutrients leached from freshly exposed soil plus nutrients from the rain water runoff from the water shed. See the problem of ignoring the watershed and not getting it vegetated promptly?. While it is wind pushed close to one shore, I would dip as much of it out as possible with a fine meshed net; mesh similar to window screen size. The pond is small enough that manually removing problem vegetation is not a big problem labor-wise. Killing it in the pond just recycles the nutrients for the next algae crop.

Note - I think ewest means to say hypereutrophic not hypertrophic. .
