This was discussed in your previous thread. Did you forget it? There are both pressure and temperature issues. At that pressure, there is a very narrow temperature range where liquid water can exist: Too high and there is vapor, too low and there is ice. During summer the maximum recorded atmospheric temperature during the day was too high, and it dropped well below freezing every night. There would only be a brief period with a "just right" temperature. That would not be conducive to bodies of liquid surface water existing for extended periods.

Ultimately, as previously noted, there could be rare eruptions of liquid underground water. Given the conditions, it is expected that most underground water would be extremely well frozen permafrost. All of this means that, if you're going to suggest an image shows flowing surface water, you are going to need very good evidence to support it. You haven't provided it.
