SB 1623 revises the approval process for dedicating water rights to the Texas Water Trust. It requires that the Texas Commission on Environmental Quality (TCEQ) review and approve all surface water rights placed in trust, in consultation with the Texas Water Development Board and the Parks and Wildlife Department. Additionally, groundwater rights placed in trust must be reviewed and acknowledged by local groundwater conservation districts. This measure aims to ensure proper oversight of water rights dedicated for conservation and environmental protection​.
