Many prairie potholes in North Dakota are filled with emergent aquatic vegetation. The paper describes briefly how evapotranspiration losses were determined for such potholes using a mass‐transfer equation in which the coefficient was evaluated by means of a water budget. Vegetation, by its presence, reduces evaporation below the normal from a free water surface so much that the total seasonal (May ‐ October) evapotranspiration loss is less than the normal evaporation loss from a pothole clear of vegetation.
