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

i. Point of Diversion (POD) GIS layer

ii. Place of Use (POU) GIS Layer

iii. 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

i. For diversions from streams, and wells*

ii. 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 POU1. Crop selection2. ET estimate (demand)3. Irrigation decision4. Potential Diversion from a stream reach

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)

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)
