Unused Rights
Unused rights are rights owned in the current AY but were not pumped and not carried over to the next AY. In general, unused rights are not effected by carryover conversion unless a large amount OYC is converted and the lower limits of a pumpers' one-year carryover limit are increased by the amount of the Annual Pumping Right (in the Central Basin, the minimum carryover limit is 20 acre-feet or 20% of APA+Leases with Flex, whichever is greater). Usually, Unused rights can only be reduced by pumping, sales or leasing.
Non-Consumptive Rights
Unused rights are rights owned in the current AY but were not pumped and not carried over to the next AY. In general, unused rights are not effected by carryover conversion unless a large amount OYC is converted and the lower limits of a pumpers' one-year carryover limit are increased by the amount of the Annual Pumping Right (in the Central Basin, the minimum carryover limit is 20 acre-feet or 20% of APA+Leases with Flex, whichever is greater). Usually, Unused rights can only be reduced by pumping, sales or leasing.

Converting Carryover to Storage
If a party has one-year carryover (OYC), they may choose to convert all or part of that carryover to storage. Parties who own water rights (an annual pumping allocation in the Central Basin or an annual right in the West Coast basin) can transfer one-year carryover into their individual storage account. If the individual storage account is full, they may use their community storage if space is available. Drought carryover (DCO) is not eligible for conversion. Please see the Storage section for more information.
