Reports identify problems in the Stockbridge Bowl called "eutrophication," a process where water bodies receive
excess nutrients that stimulate excessive plants growth
The Stockbridge Bowl has a serious weed problem and a number of measures are needed to correct the lake’s deterioration:
-Harvest weeds to remove excess nutrients
-Strictly manage septic systems
-Use non-phosphate detergents
-Lower the lake’s level in winter to kill weeds.
Phosphorous is the critical nutrient which is in oversupply. 75 % of current phosphorous supply comes from erosion of developed land, 11% comes from septic systems, 10% comes from the atmosphere.
