Evaporation lossA pool this size can lose approximately 70 gallons per day in summer (~0.25" per day evaporation rate). Using a pool cover can reduce evaporation by up to 95%, saving water and chemicals.

This is an estimate based on idealized pool shapes. Actual pool volumes may vary due to contours, benches, steps, and construction tolerances. For precise volume, consult your pool builder or use the bucket method for existing pools.
