Sometimes people fill in the drainages and sloughs in their neighborhood to get more buildable land and then wonder why they get flooded out now and then. Best work with nature rather than trying to conquer nature.
My neighbor hood is in a classic karst region. There are many sinkholes varying from medium to large. Development resulted in covering the bottoms of several. The result is always runoff filling and sometimes flooding. The dirt fill usually clay has to be removed before proper drainage is restored. The drainage is underground to the river half mile away.
