Envision’s Water Master Model

(water rights)

  • Based on Western Water Law, and a prior appropriation permit process

  • Uses Oregon Water Resources Department (OWRD) Water Rights data sets

    • Point of Diversion (POD) GIS layer

    • Place of Use (POU) GIS Layer

    • Individual Water Right’s Information Search (WRIS) in table format

  • Relates OWRD data to the WW2100 IDU, and stream layers

  • Satisfies daily demand in each IDU

    • For diversions from streams, and wells*

    • For in-stream, irrigation, and municipal demands

* - under construction


The IDU layer and a Water Right’s POD and POU

For each IDU within a POU

Crop selection

ET estimate (demand)

Irrigation decision

Potential Diversion

from a stream reach


Envision Water Master Terminology

Available Water (stream or well)

Unappropriated Water

IDU water demand (crop and/or municipal)

Allocated Water

Regulatory Demand

Summation of daily Irrigation rates for 2011


Daily irrigation rate

(WW2100 study area m3/sec)

  • Other variables for daily water use per IDU:

  • - Number of IDUs

  • Area of IDUs

  • Use (irrigation, municipal)

  • Source of diversion (well or stream)

IDU water demand (crop and/or municipal)

Water Right Shut Off

(log conflict metrics)

Minimum flow

Unavailable Water


Water right (WR) conflict and shut-offs

(measured in number of WRs, areas, and diversion rates)

Level 1 Conflict

Sunday Monday Tuesday Wednesday Thursday Friday Saturday

Level 2 Conflict (consecutive days)

Sunday Monday Tuesday Wednesday Thursday Friday Saturday

Water Right shut-off

If a WR experiences X consecutive days of shut-off, then the WR is shut-off for

remainder of the calendar year

X – is defined at run time to explore different scenarios


Envision’s Water Master To Do List

(water rights)

  • QA/QC the most recent runs

  • Water Master workshop to define post run outputs, and data sets

  • A closer look at in stream uses (power generation etc..)

  • Include diversions from wells (coupled with ground water modeling)
