This image shows a roundish crater with three channels breaching the rim and extending to the south. The crater has been filled by sediments and may have been an ancient lake.

When the water began to overtop the crater rim, it would rapidly erode a channel and, at least, partially drain the lake.

Be sure to look at the stereo anaglyph.
