Swimmer's Itch = Duck Mites?

In Winnipesaukee's shallower waters, I'd guess that a few could be out there—depending on the winds.

The "mites" (cercaria )are just large enough to see! From my aquarium experience with other tiny critters of about the same size, the cercaria could be visible using a strong light.

Try using a silk cloth as a seine, then release the filtered contents into a clear glass. In the right light—watching the sun refracting through their bodies—you may be able to see them swimming around as tiny "Crystalline Entities".

After local winds have driven them near shore, perhaps ask a town lifeguard about this test at a beach?
