With the enactment of Indiana Code 14-25-5 (Emergency Regulation of Surface Water Rights) by the 1990 General Assembly, freshwater lake owners are protected against the impacts of high capacity pumping if it substantially lowers the level of the freshwater lake, resulting in significant environmental harm to the lake or adjacent property.

The temporary order may restrict the quantity of water extracted by the SWWF and also provide for the restoration of the normal water level of the lake.
