ARVIN-EDISON WATER STORAGE DISTRICT

Emergency Well Replacement Construction In Progress

of 9

WATER SUPPLY Friant Division Central Valley Project (CVP)

• The 2020 Water Year allocation increased as follows: o 55% Class 1 (22,000 AF) o 0% Class 2

• Exhibit “A” provides additional supply information for 2020 Water Year San Joaquin River Restoration Program (SJRRP)

• The 2020 Runoff Year is currently estimated at 920,000 AF of natural river runoff in the SJR watershed, which is a “Dry” year type pursuant to SJR settlement and accordingly, the SJRRP would receive 211,123 AF of water supply

• During Dry year types, URF supplies are made available (approximately 65,000 AF with 3,250 AF District share)

• Recapture supplies are estimated at 36,000 AF (approximately 2,500 AF District share at this time and subject to change)

• SJRRP initially requested 3,800 AF from District from the 2016 Exchange (up to 7,000 AF is available); however, with the improved hydrology the exchange is deferred

• District’s RWA credit beginning balance is approximately 90,630 AF (subject to reconciliation and staff review). RWA credits allow the District to purchase water for $10/AF during wet periods when RWA water is declared.

Shasta System CVP

• The 2020 allocation for south of Delta Ag remains at 15%

State Water Project (SWP)

• The 2020 SWP remains at 15% Kern River

• 2020 supplies are estimated at 55% of average

Water Bank Facilities

• Given limited surface supply allocations, heavy reliance on wellfields (~73,000 AF) is anticipated for the 2020 Water Year

Metropolitan Water District (MWD) Water Management Program

• MWD beginning balance is 142,257 AF in water bank reserves

• MWD has not requested return for the 2020 Water Year however District offered to deliver its carryover supplies through February

• The District obtained its tenth consecutive year approval from the State Water Resources Control Board regarding a Petition for a Consolidated Place-of-Use (CPOU), which now expires on July 15, 2020; however, a 2020 CPOU is currently being drafted

• The CPOU petition includes the ability to exchange all types of Arvin-Edison supplies with MWD including unbalanced exchanges

• The District’s 10-year NEPA documentation is complete and approved until March 21, 2024. Staff, along with MWD, DWR, and Reclamation continue pursuit of a long-term CPOU approval through November 2035

Wellfield Operations Continue Through April

of 9

Rosedale-Rio Bravo Water Management Program

• The District’s 2020 beginning account balance for water held in RRBWSD is 74,462 AF

• District anticipates receiving 10,000 AF from the program from May through September to supplement other surface water supplies

Kern Delta Water District:

• Staff continues meeting with KDWD staff to advance water management opportunities including joint partnership in groundwater recharge facilities and additional interconnection facilities

• Kern Delta is returning water to MWD under the KDWD/MWD program and an operational exchange is occurring with the AE/RRB program

District Partnerships: The District has participated in water management programs with the following districts/agencies in Water Year 2020:

County of Fresno Del Puerto Water District Kern Delta Water District Madera Irrigation District Metropolitan Water District Pixley Irrigation District

Rosedale Rio Bravo WSD San Joaquin River Restoration Program Shafter-Wasco Irrigation District Tulare Irrigation District Westside Mutual Water Company
