Nutrient Load,Trophic Conditions and Restoration Prospects of Lake Maggiore

The trophic status of Lake Maggiore is revised following the OECD (1982) approach to eutrophication, using detailed, long-term data on nutrient sources and loads, and in-lake nutrient, chlorophyll and phytoplankton conditions as a factual basis. Alternative hypotheses of phosphorus load reduction are considered in the light of partial measures already under way. The need for an integrated, whole-basin restoration strategy is emphasized.
