Narrative of
WaterMaster
steps for irrigation
Each OWRD POD for the WW2100 study area are listed in the
WaterMaster
POD input file
The POD input file is sorted from Senior to Junior. Diversion can be from a ground or surface source.
Each day of the year
WaterMaster
begins with the most senior POD input file.
This POD might be one of many PODs in an OWRD paper water right
Each POD is associated with a POU which is represented by a POUID in the POD input data file.
Each POU intersects one, or many IDUs.
Using the POU input data file and the POUID, a list of intersecting IDU_INDEXS are returned.
For each IDU_INDEX the POU must intersect the IDU by 60% or more.
If true in step 8 then this POD will satisfy the demand in the IDU.
The water diverted is equal to, Demand * OWRD POD rate / sum of all OWRD POD rates for this IDU
Consider next IDU in
from the list returned in step 7.
considered t
he next junior POD in the POD input data file. This POD may or may not be part of the
s
ame 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.Slide2
IDU_INDEX 95934. Maximum daily applied irrigation for 2010 is 29.3 acre-ft.
Area
of IDU = 1012937 m2 = 250 acres.29.3 acre-ft / 250 acres = 0.12 acre-ft per acre
This IDU has two separate irrigation water rights that have separate POUs that intersects this IDU by more than 60%.
One WR has a ground water POD, the other a surface water POD. Both water rights have appropriation dates of 1978 (as mental exercise consider the appropriation dates as different) . See the Excel file “snips_from_WaterMaster_inputFiles_IDUINDEX_95934.xlsx” for the input data files that WaterMaster uses.Slide3

POD
is surface water.Slide4
POUID 103265 solid yellow. Fragmented, not all the POU intersects with IDU 95934.
Slightly different POU than 103269.
POD is ground water.
