I'll have a closer look in the next couple days and see if I can get some closer photos. I may have a chance to have a look microscopically before the project starts as well. Unfortunately that microscope doesn't have a camera hooked up to it yet though.

The water isn't turbid but has the appearance of dilute black coffee which is typical of this region.

Thanks for your feedback. I'll put up some more photos when I have them.
