Abstract: Long-term trends in phosphorus and phytoplankton concentrations were studied in Slapy Reserv.,as a representative of most reservoirs with medium flushing rate in the Czech Rep. Phosphorus and chlorophyll a concentrations increased from the 1950s to the middle 1990s as a consequence of an increase of phosphorus use and release into surface waters by human population. The decrease in phosphorus and chlorophyll a concentrations during the last decade can be interpreted as a beginning of a long-term recovery of Slapy Reservoir resulting from the decrease in P-loading into the surface waters by human population. Further possibility how to reduce phosphorus input to the surface waters is especially P removal from municipal waste waters. After higher reduction of phosphorus from waste waters, accomplishable especially by the entire elimination of P from detergents and by technologies of enhanced P removal in waste water treatment facilities,the trophic status of Slapy Reserv. lower than in the 1950s can be expected.
