Separate from the Martian outflow channels, or the river valley networks, are large Martian lakes (600 km, or ~1000 miles across) which exhibit evidence of a periodic and catastrophic release of water in the form of floods. This evidence is found with an examination of the shorelines surrounding the lakes.
An analysis of the combined evidence from the Martian outflow channels, the river valley networks, and catastrophic flooding suggests two possibilities for the global Martian water cycle.
