WATER SUPPLY Friant Division Central Valley Project (CVP)

• The 2020 Water Year allocation increased as follows: o 65% Class 1 (26,000 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 902,000 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 202,197 AF of water supply

• During Dry year types, URF supplies are made available (approximately 38,000 AF with 1,900 AF District share; additional Priority URFs as a result of prior agreement are expected to generate approximately 5,300 AF)

• Recapture supplies are estimated at 31,700 AF (approximately 1,850 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 is 20% State Water Project (SWP)

• The 2020 SWP is 20% Kern River

• 2020 supplies are estimated at 55% of average Water Bank Facilities

• Given limited surface supply allocations, heavy reliance on wellfields (~74,000 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 has been requested

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

Page 2 of 10

• 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

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 between 8,000 and 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:

Buena Vista Water District Chowchilla Water District City of Lindsay County of Fresno Del Puerto Water District Garfield Water District Hills Valley Irrigation District Kern Delta Water District Kern Tulare Water District Lewis Creek Water District

Madera Irrigation District Metropolitan Water District Pixley Irrigation District Rosedale Rio Bravo WSD San Joaquin River Restoration Program Shafter-Wasco Irrigation District Tri-Valley Water District Tulare Irrigation District Westside Mutual Water Company

WATER SUPPLY WATER QUALITY SUMMARY

Calcium Magnesium Sodium Bicarbonate Chloride Nitrate

Water Supply Water Quality Note: 1

Positive flow rate is reverse flow into the District. Where the reported value is ND, the method detection limit is entered.

NONE DETECTED. A MEASURE OF ACIDITY. A pH < 7 IS ACIDIC, pH = 7 IS NEUTRAL,

pH > 7 IS BASIC. NORMAL RANGE IS 6.5 - 8.4. A pH > 8 MAY

NEED TO BE BUFFERED FOR PESTICIDE APPLICATION. AFFECTS

NUTRIENT AVAILABILITY.

NOT AVAILABLE OR NOT TESTED.

mg/l: MILLIGRAMS PER LITER; SAME AS PARTS PER MILLION (ppm).

Reverse flow into the District South Canal (Sycamore check gate was closed).


Constituent ran past sample hold time.

me/l: MILLEQUIVALENTS PER LITER; SAME AS EQUIVALENTS PER MILLION (epm).

ELECTRICAL CONDUCTIVITY. A MEASURE OF WATER SALINITY;

SOIL - IN MILLIMHOS PER CENTIMETER (mmho/cm); WATER -

MORE OFTEN, IN MICROMHOS PER CENTIMETER (umhos/cm). EC

< 700 (umhos/cm) HAS NO RESTRICTIONS FOR AGRICULTURAL

USE. EC < 200 (umhos/cm) CAN REDUCE INFILTRATION RATE.

INTAKE: SAMPLE TAKEN AT COTTONWOOD RD. SOUTH OF PANAMA LANE.

NORTH: SAMPLE TAKEN DOWNSTREAM OF SYCAMORE CHECK GATE.

SOUTH: SAMPLE TAKEN DOWNSTREAM OF TEJON CHECK GATE.

INTERTIE: TERMINUS OF SOUTH CANAL (S93 FOREBAY).

EVALUATE WITH EC.

SODIUM: FOR SURFACE IRRIGATION: SAR < 3 IS GOOD. FOR SPRINKLER IRRIGATION: SODIUM < 3 me/l IS

GOOD. HARDNESS: HARD WATER, INDICATING CALCIUM AND MAGNESIUM, IS

BENEFICIAL FOR AGRICULTURE.

NITRATE: NITRATE IN WATER SLIGHTLY REDUCES FERTILIZER REQUIREMENT.

BICARBONATE: BICARBONATE < 1.5 me/l IS SATISFACTORY FOR OVERHEAD SPRINKLERS.

SODIUM ADSORPTION RATIO. A RATIO OF SODIUM TO CALCIUM

AND MAGNESIUM. CHLORIDE: FOR SURFACE IRRIGATION CHLORIDE < 4 me/l IS GOOD.

TDS: TDS < 450 IS ACCEPTABLE FOR UNRESTRICTED USE.

SAR = 3 - 6 AND EC > 900 ACCEPTABLE

GYPSUM: AMOUNT OF CALCIUM SULFATE IN POUNDS PER ACRE-FOOT OF WATER APPLIED. INCREASES WATER

PERMEABILITY AND HELPS CORRECT EXCESS SODIUM. INCREASES CLAY FLOCCULATION FOR

INCREASING PERMEABILITY.BORON: BORON < 0.50 mg/l IS SATISFACTORY FOR ALL CROPS.

EXCESSIVE BORON IS PHYTOTOXIC (BURNS) TO PLANTS.
