8. Water Protection Fund Expand use of Water Protection Fund monies to include:Expand use of Water Protection Fund monies to include: –Grants for purchase or lease of any water (not just CAP or effluent) or water rights that will protect or restore riparian habitats –Grants to qualified entities for acquiring conservation easement Would require agreement by the Water Protection Fund BoardWould require agreement by the Water Protection Fund Board

9. Enforcing Surface Water Law Currently ADWR has very limited authority to bring an enforcement action against an entity that makes an illegal diversion or impoundment of surface water.Currently ADWR has very limited authority to bring an enforcement action against an entity that makes an illegal diversion or impoundment of surface water. ADWR would ask for the authority to seek civil penalties in Superior Court of up to $10,000 per violation per day for such offenses.ADWR would ask for the authority to seek civil penalties in Superior Court of up to $10,000 per violation per day for such offenses.

11. Rivers and Riparian Areas Establishing river and riparian protection zones that would limit or prohibit well drilling would be a proactive approach to avoid enforcement actions brought about by the Endangered Species Act, senior appropriators or the Gila and Little Colorado River Adjudication Court.Establishing river and riparian protection zones that would limit or prohibit well drilling would be a proactive approach to avoid enforcement actions brought about by the Endangered Species Act, senior appropriators or the Gila and Little Colorado River Adjudication Court. This would not affect existing wells.This would not affect existing wells. The zones could involve a specific distance from a flowing river and riparian area or a zone determined by hydrologic and physical characteristics.The zones could involve a specific distance from a flowing river and riparian area or a zone determined by hydrologic and physical characteristics.
