We haven't found any yet although there are erosional features on Mars that suggest the passage of water. Large parts of Mars get covered in ice in it's winter but this is not frozen water, it's frozen carbon dioxide. Scientists are hoping that there may be subterranean water on Mars.

There was news about this just couple of weeks ago, that there is evidence for liquid water on Mars... but they don't last long because of low pressure. Water evaporates right away.
Any water that is there exists in ice cap or as underground ice. this underground ice could possibly melt and come up to the surface by geological forces.
Scientists studied photos taken short time apart (years?) and saw features that were not present in the earlier photo that was present in the recent photo. And these features could only be produced by liquid water (they see a newly formed gully and some precipitated minerals). Obviously, the water was no longer there, but it shows that it was there for a short period!

Not for sure. We have photographs that show what looks like erosion from running water on the side of a slope (in a crater wall). 5 years ago it wasnt there now it is. It looks like is was carved out by water running down the hill. Best guess is water, frozen underground spurted (or oozed) up out of the ground for a very short time and ran down the slope before it all evaporated.
So far nobody's come up with a better explanation for the pictures. So far. BUt no we're not saying there is water on the SURFACE of Mars, normally.

It's too cold for liquid water to exist on its surface and too cold to rain.& mar's atmosphere is also too thin to permit any significant amount of snowfall.
Even if some internal heat source warmed the planet up enough for ice to melt, it wouldn't yield liquid water. The Martian atmosphere is so thin that even if the temperature rose above freezing the ice would change directly to water vapor.
But there must have been running water, evident from the massive outflow channels that are found,

Pervifull Loll said there was canls but later prouved wrong and fantastik. Later he proveld that martians were not their and had oviosly left no evidence behind. More recenly orbiters show discrepncies between differn timed pictures. The planet is two dry to whole lickwid water on the surfice but maybe for 5 seconds.

There is no chanace for existing of running water on mars because the average temperature on mars is -128degrees.at this if water is present it would be in frozen state.

Sure there is, in fact, SETI has recorded radio signals from Martians griping about their water bills.
Seriously. The idea of liquid water on mars is not so farfetch.
Here is an article about some new discoveries from the rover.

Recent knowledge indicates that within the last few hundred years, water (or something like it) flowed on Mars!
Water? Maybe!
Only time will tell!

Yes,
In Mars there is a place that we call The Polar Ice Cap!

It is too cold and the air pressure is too low for liquid water to exist on the surface of Mars.
