Relating to the liability of a landowner for the withdrawal and beneficial use of groundwater.

SB 59 amends Texas law to clarify landowners' liability when withdrawing and using large volumes of groundwater (25,000+ gallons per day) for beneficial purposes like irrigation. It states such landowners are generally not liable for interfering with neighbors' water use unless their withdrawal directly harms a neighbor by lowering water tables or unreasonably affects a watercourse or lake. The bill only applies to legal claims arising after its effective date, which is 91 days after the legislative session ends. This change modifies existing liability rules but does not alter landowners' fundamental rights to use groundwater.
