Reply to comment by JoshSidekick in TIL eels swim from a lake in Australia through stormwater drains and across the ocean to lay eggs in New Caledonia where they die. Their eggs hatch and make the return journey back to the lake they came from. by Aussiewhiskeydiver
There were probably just nice little rivers, streams and small tributaries previously. When we pave over areas to build up, we cap all of the streams in pipes and bury them, routing all of the runoff into them. I expect it was something like this.
