This Baseline will bedetermined using the average water use for each field from a 10-yearrunning average (1997 through 2006 for the 2008-2009 Fallowing Program)with the maximum and minimum years eliminated fromthe average.•Ability to turn off water to fields with multiple tenants.•Multiple fields and/or tenants sharing a single headgate must haveverifiable water use records.Fallowing Program Eligibility Criteria(con’t)•Charges for delivered water and water availabilitysubject to IID’sRegulation # 11 must not be delinquent.•Field participation in IID Fallowing Programs is limited to twoof every fouryears and if a field is in the program for two continuous years,it is noteligible for the subsequent two years.•If a service pipe uses water from the headgate of aproposed field, theFallowing Party must submit a written plan outlining how the service pipeneeds will be accommodated and make arrangements toimplement thisaccommodation prior to the Program start date.•Each proposed field must remain zoned agriculture for the contractedfallowing period.•Any Fallowing Party who has been involved in the breach of a previousProgram may be deemed ineligible.Fallowing Program ContractProvisions•Tenants are responsible for obtaining all landownerapprovals for programparticipation.•Fallowing Party will consider the impact of fallowing lands subject to aWilliamson Act Contract.•Fallowing Party shall be responsible for weed control and expense asrequired by Imperial County’s Weed Abatement Ordinance.•Fallowing Party shall be responsible for dust control as described in theAgreement.

Those fields not offered contracts based on the random selectionprocess may be rolled over into the next FallowingProgram.Fallowing ProgramCompliance & Verification•July 1-SAP crop code revised to reflect FP participation,effectivelyeliminates ability to order water on FP fields•Delivery gates locked (where possible) or physicalblockinstalled/verified for all FP fields•Quarterly field inspections/photo verifications byIID staff•Semi-annual field and data validation (5% of FP acreage)by USBRIID FALLOWING PROGRAMS2003-2004 Emergency FP(12/1/03-12/31/04)•$1,774,782•69 fields•5,764 acres•38,641 acre-feet water yield (at farm)•6.7 af/ac (at-farm) average program yield2004-2005 FP(7/1/04-6/30/05)•$3,356,392•118 fields•12,126.5 acres•67,273 acre-feet (at farm) water yield•5.5 af/ac (at-farm) average program yield2005-2006 FP(7/1/05-6/30/06)•$3,180,992•105 fields•11,676.2 acres•69,764.1 acre-feet (at farm) water yield•6.0 af/ac (at-farm) average program yieldIID FALLOWING PROGRAMS(con’t)2006-2007 FP(7/1/06-6/30/07)•$5,326,065•169 fields•17,984.4 acres•96,394.8 acre-feet (at farm) water yield•5.4 af/ac (at-farm) average program yield2007-2008 FP(7/1/07-6/30/08)•$6,246,532•150 fields•16,172 acres•89,512 acre-feet (at farm) water yield*•5.5 af/ac (at-farm) average program yield*
