@John: Going against the current is certainly harder that going with the current, but your body is more than up to the task, although the water here has risen to just about knee depth on you, making walking a slog. Your check of the matrix yields the information that there are several hidden devices within 100m of your location. Most of them are up above you, but there are three below you and one on what is pretty much your level.

The water moving past you pretty much drowns out all other noises.
