Water conservation; requiring Oklahoma Water Resources Board promulgate rules for commercial water well spacing; effective date.

HB 1544 requires the Oklahoma Water Resources Board to create regional rules for spacing commercial water wells across Oklahoma's nine defined geographic regions. The rules must account for local groundwater availability, recharge rates, impacts on existing wells and aquifers, and regional water needs (including agriculture, industry, and municipalities). The Board must assign one staff member per region to oversee compliance with these regulations. The bill takes effect on November 1, 2025, directly affecting commercial well operators and groundwater management practices statewide.
