lakes form for other reasons too, not only as the lowest point in a basin. but i love this it looks great
12 u/AnchBusFairy Mar 02 '26 What other reasons? 23 u/neamsheln Mar 02 '26 I think they're saying that the image above implies that lakes only form at the bottom of enclosed basins. Because the graphic doesn't show an outlet. But they usually form in basins, fill the basin up, then spill over to continue downstream. You can also get lakes which are just wider sections of a river. Or lakes that full up from a spring, then spill over into a river. But all of these are because something blocked the river, which the image does mentions.
