When lands that had a history of irrigation are repurposed, these rights remain intact, enabling former agricultural users to retain access to their water allocations. This helps to mitigate the potential impacts on water availability resulting from changes in land use, maintaining a historical continuity of water access.

The other options do not accurately reflect the nature of rights associated with converted lands. Type 1 and Type 2 rights pertain to different classifications of water rights that do not specifically address the historical context of previously irrigated lands. Effluent rights are related to the reclaimed wastewater for specific uses and do not pertain to the conversion of irrigation land. Thus, "grandfather
