New ponds with all dirt clay shorelines will always tend to stay turbid especially after rain events. Wind action against exposed shorelines continually resuspend settled clay particles. Frequent or constant aeration will also help to keep tiny particulates suspended in the water column. As these pond age they build up an organic bio-accumulation layer that over time tends to cover the exposed bottom soils. This bio-layer including algae and weeds separates the clay from the overlying water and aged ponds often become more clear. In ponds with more sandy soils this constant resuspension of colloidal clay particles does not happen as much due to lack of clay bottom sediments.

Lots of ponds in NW Ohio get the entire shoreline lined with gravel or large crushed limestone down to a depth of 2 to 4 ft. These ponds quickly become clear 4 to 8ft even in clay bottom soils providing no sediment disturbing fish are present. It is not uncommon for some of these ponds to have water clarity of 10ft to 18ft. This often occurs in ponds with only bass.
