In the paper the author focuses attention on the problem of the influence of lateral density changes in topographical masses on gravity and geoidal height computation. In computing the geoidal heights, the density is usuall modelled by the mean crust density p0=2670kg.m-3. The density of water in lakes differs significantly from this value. To answer the question of how large an error can be caused by this onfluence we divide it into primary, secondary and idirest effects. An estimation has been made for an artificial lake near the pumped-storage power station in Zarnowiec, Gdansk district.
