Since 1992, the Onondaga Lake Partnership has supported the efforts of the United States Geological Survey (USGS) in the following remedial activities: the diversion of surface water away from the mudboils, the installation of a dam on the stream that flows from the mudboils area, and the drilling of wells to reduce the pressure around the mudboils (21). The installation of several depressurization wells has led to dramatic decreases in sediment loading; an average of 30 tons per day was reduced to 1 ton per day.
