No water at Tantalus Creek from Steamboat Geyser

This is the amount of water that reached Tantalus Creek after yesterday's eruption: 0.5 cubic feet per second.

Usually it's more than 2 cubic feet per second. Unless someone built a dam or something like that, what could explain this?

Judging from the notes of the people in the area, there seems to be no water shortage in the geyser system. Also, considering that it took Steamboat Geyser more than 26 days to erupt this time, the area doesn't appear to be hotter than usual. But then, what gives? If there is water and no excessive heat and the channel from Steamboat Geyser to Tantalus Creek is operational, why is there no water at Tantalus Creek?

I cannot be sure of those assumptions. But they seem to be correct. Well, presumably more water was vaporised before the eruption this time than usual. The frequency of eruptions is proportional to the excess heat, if a fixed amount of water has to reach a fixed temperature. Quite possibly the amount of water that is needed to reach a certain temperature before an eruption decreases with rising temperature, owing to the violence of the generated steam. In other words: the frequency of eruptions may rise overproportionally with the heat. But I doubt that it rises anywhere near quadratically with it, i.e. that twice the excess heat means half the water that needs to be heated. This time the amount of water on top of the steam fell to less than 25%, so I don't think that the aforementioned overproportionality can account for it. However, even of this I am not certain. More likely though to my mind is a change in the architecture of the geyser system, new tunnels formed or old ones collapsed.

If you want to prove yourself as a science journalist, try to find some qualified elaboration on these issues. Perhaps it was just the wind blowing in the wrong direction, but as a test of the functioning of the division of labour and the dissemination of knowledge in particular, try to find some qualified elaboration on the aforementioned questions. I would start with the physics department of the University of Cambridge, East Anglia. They have a decent applied physics section there. But if you would actually pick up this task, perhaps some propulsion engineer could also help you, you would hear almost as often as a job applicant hears that he hasn't quite the right set of skills, that these kind of questions aren't really studied here.
