Water and water rights; defining term. Effective date.

SB 1009 defines a "basin integrity study" in Oklahoma law as a scientific study to determine sustainable water flow levels in rivers and streams for specific basins and seasons. These studies must consider water needs for drinking, farming, tourism, environmental health, and economic development. The bill explicitly states such studies cannot be used to revoke private water rights or interfere with existing senior water permits. The definition becomes effective November 1, 2025.
