Multiple ponds and lakes have been around for 100s if not 1000s of years, sediment goes into them every rainfall, how can they stay there so long and not fill in?

Short answer, compaction. Long answer is, it’s complicated and every system has different variables as to how much sediment is depositing, fluid flow in/out of the lake or pond. But in general, as sediments get buried by new incoming sediments, it compacts due to the weight of the Warner and sediments above which leads to a reduction of pore space between individual grains, thereby reducing its volume.
