HB 599 Louisiana House · 2026 Regular Session

WATER/RESOURCES: Prohibits the sale of Louisiana running surface water outside of the state

HB 599 prohibits the sale of Louisiana's running surface water to entities outside the state. It directly affects businesses or entities seeking to purchase Louisiana water for use beyond Louisiana's borders. The bill enacts a new provision (R.S. 30:961(L)) banning such sales and repeals a prior section (R.S. 30:961(I)) that allowed the state secretary to approve cooperative agreements for out-of-state water withdrawals. This creates a clear policy change preventing the export of state-owned surface water for use outside Louisiana.
