¹See Section 2.10 (Table 2-13) for a more detailed description of how projected demands were calculated. ²The supply from Canyon Reservoir to CRWA of 2,780 acft/yr represents a portion of the 50,000 acft/yr current supply from Canyon Reservoir ³The total projected supply does not include the entity’s contract with GBRA. For purposes of this planning effort, those contracts were considered to be a part of GBRA’s projected demand.
