Footnotes: 1. Due to rounding to the nearest acre-foot, totals may differ from the sum of the monthly values. 2. Diversion amounts include any deliveries to the Fort Mojave Tribe by the City of Needles. Diversion values listed as pumped from river and wells are provided by the Fort Mojave Tribe 3. All or a portion of this Colorado River use is offset by pumping from the LCWSP. Details shown in the LCWSP sect 4. Water conserved by IID and transferred to SDCWA, in accordance with the CRWDA, Exhibit B, Column 5, and the IID/SDCWA Water Transfer Agreement and water allocated to SDCWA as a result of the CCLP and AACLP pursuant to Article 10 of the October 10, 2003 Allocation Agreement. At SDCWA's election, the water was delivered by the Secretary to Lake Havasu u of the CRWDA and there made available by SDCWA to MWD under the terms of the SDCWA/MWD Exchange Agreement. 5. Reported as an annual total only then distributed monthly according to the monthly use patterns of nearby users. 6. These values represent an estimate of the amount of diversions required by the Tribe to provide domestic water service for users within the reservation. 7. Unassigned measured returns include drainage from the Indian Unit and the Bard Unit in the Reservation Division but excludes seepage from the AAC. 8. This entry represents water conserved by IID, transferred to SDCWA and delivered to the , in accordance with CRWDA, Exhibit B, Column 7, and the IID/SDCWA Water Transfer Agr 9.
