The most effective ameliorative action was the hydrological intervention of opening the new lake mouth and channel to the sea through the barrier beach at Satapura. This improved the spatial and temporal salinity gradients of the lake to maintain the unique characteristics of an estuarine eco-system. This intervention was undertaken after detailed scientific studies, including 3-dimensional mathematical modeling and hydraulics studies on a model prototype, were carried out by the Central Water and Power Research Station, Pune and National Institute of Oceanography, Goa. In September 2000, the desiltation of the channel connecting the lake to the sea and opening of a new mouth to restore the natural flows of water and salinity levels was carried out. These actions resulted in a notable increase in the lake's fish yield and a reduction of freshwater weeds. The new mouth reduced the length of the outflow channel by . Opening of the new mouth provided a favorable increased salinity regime throughout the lake with less fluctuations and improved water clarity.
