Can a river be put under enough pressure to jet straight up for a mile?

I've been mulling over an idea for my preferred RPG setting, and I wanted to check if anyone knows the following:

Is it possible for a river to flow underground for miles, and then suddenly be put under enough pressure to jet a mile or so into the air (as the focal point of a city) and then flow away as a normal river, out the other side of the city? I prefer natural solutions, but mechanical can be included if necessary. No magic or nonsense :D

The setting, if you have a mechanical solution, is Renaissance.

Geysers can get pretty big, but they're often the result of a sudden release of pressure, whereas this would need to be constant.
