Water Law

While other states have been addressing issues of surface and subsurface water rights for many years, the area of water law has only recently begun to assume prominence in Louisiana, long considered to be a "water-rich" state. In the past few years, the "water law" domain in Louisiana has seen extensive activity, including the enactment of new statutes governing surface water use, new administrative regulations governing groundwater use, and new opinions of the state Attorney General on the subject of surface water use and the potential liability of persons or entities who utilize surface water without authority. With committees and entities like the Louisiana Groundwater Commission at work drafting additional statutes, there can be no doubt that water law in Louisiana will continue to develop in the immediate future.
