Stream Reach Discharge (SRD) m3/day IDU Water Demand (m 3/day) Calculate Available Reach Discharge (ARD) m3/day. ARD = SRD – ISU - OSU Is ARD ≥ IDU water demand noyes Consider next junior WR Is the Use an “In Stream” Use (ISU) Add Demand rate to “Out Stream” Use (OSU) Add Demand rate to ISU yes no Flow Model (daily time step loop) HRUs (comprised of stream reaches) Water Right loop ( begin with Senior WR ) Have all IDUs been considered? Consider next IDU Subtract Out Stream Use from Stream Reach Discharge SRD = SRD - OSU IDU loop ( A Point Of Use can have multiple IDUs) noyes Have all WR been considered Consider next WR no Aggregate SRD to HRU yes Log Conflict Metrics

Narrative of WaterMaster steps for irrigation 1.Each OWRD POD for the WW2100 study area are listed in the WaterMaster POD input file 2.The POD input file is sorted from Senior to Junior. Diversion can be from a ground or surface source. 3.Each day of the year WaterMaster begins with the most senior POD input file. 4.This POD might be one of many PODs in an OWRD paper water right 5.Each POD is associated with a POU which is represented by a POUID in the POD input data file. 6.Each POU intersects one, or many IDUs. 7.Using the POU input data file and the POUID, a list of intersecting IDU_INDEXS are returned. 8.For each IDU_INDEX the POU must intersect the IDU by 60% or more. 9.If true in step 8 then this POD will satisfy the demand in the IDU. 10.The water diverted is equal to, Demand * OWRD POD rate / sum of all OWRD POD rates for this IDU 11.Consider next IDU in from the list returned in step considered the next junior POD in the POD input data file. This POD may or may not be part of the same OWRD Water Right as the POD before. This POD, may or may not, contribute to satisfying the demand in any of the previously irrigated IDUs. This POD may have a different seasonal pumping schedule. This POD’s beneficial use could be municipal. This POD could be for ground water for surface water. Or, any combination of the aforementioned in this step. There are 23,751 unique irrigation PODs in the POD input data file.
