ABSTRACT-We have detected a slow degradation in the water quality of Twin Cities Metropolitan Area lakes du~ to phospho_rus enrichment. While the water quality of the lakes does not appear to limit most uses, nmsances do exist. We have further discovered that commonly-used watershed treatments such as wetland diversions and ponding, are ineffective ~t reversing or completely mitigating the degradati~n following land development. Th_erefore, we are su~gestmg that lake managers reduce the external loading of phosphorus to the greatest ~oss_1ble extent; then, 1f further water quality improvements are necessary, that measures which treat eutroph1cat1on-related symptoms be considered for the long-term management of the lakes.
