Two questions were asked: (1) Will septic tank diversion reduce symptoms of eutrophication in the Twin Lakes, two similar dimictic lakes, and (2) Will a maximum hypolimnetic dose (residual dissolved aluminum < 0.05 mg/l) of aluminum sulfate (alum) reduce sediment phosphorus (P) release and further improve them. After diversion, P in lakes and streams declined and plankton biomass declined, but during 5 years of monitoring after diversion, P and biomass remained those of moderately eutrophic lakes, and P income remained above 'permissible'. Non-point sources were important. In laboratory and field tests, maximum dose, which is related to alkalinity and determined by 'jar tests', was effective in retarding P release from sediments.
