Relating to the permissible uses of the Texas water fund.

HB 3315 amends Texas Water Code Section 15.502(b) to clarify the specific state funds the Texas water fund can transfer money to, including existing programs like the water assistance fund and new water supply fund. The bill adds a new provision (subsection 4-a) specifically authorizing transfers to the flood infrastructure fund, while listing eight other designated accounts such as the state water implementation fund and rural water assistance fund. This procedural change does not create new programs but restricts fund usage to these nine explicitly named accounts. The bill takes effect September 1, 2025, and affects how state water funds are distributed to designated water infrastructure and assistance programs.
