(a) Until a water right is perfected to the full extent provided by § 11.026 of this code, the commission may issue permits for a term of years for use of state water to which a senior water right has not been perfected.
(b) The commission shall refuse to grant an application for a permit under this section if the commission finds that there is a substantial likelihood that the issuance of the permit will jeopardize financial commitments made for water projects that have been built or that are being built to optimally develop the water resources of the area.

(c) The commission shall refuse to grant an application for a term permit if the holder of the senior appropriative water right can demonstrate that the issuance of the term permit would prohibit the senior appropriative water right holder from beneficially using the senior rights during the term of the term permit. Such demonstration will be made using reasonable projections based on accepted methods.
(d) A permit issued under this section is subordinate to any senior appropriative water rights.
