It might settle out some, and another important point to remember is that all dams have some type of seepage issues. Since it has gotten a little warmer in August some of your loss is due to evaportation. Maybe not all of it but some of it is. That is the natural way of pond life, they draw down in summer and fill back up during fall and winter rains. If you think you have a problem with seepage you can estimate how much water you are losing due to evaporation and then compare that to how much water you have actually lost that will tell you how much water you are losing. It is not uncommon to lose 1 inch of water every 3-4 days during summer months, jsut due to evaporation.
