1. 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

2. The IDU layer and a Water Right’s POD and POU For each IDU within a POU 1.Crop selection 2.ET estimate (demand) 3.Irrigation decision 4.Potential Diversion from a stream reach

3. Envision Water Master Terminology Available Water (stream or well) IDU water demand (crop and/or municipal) Allocated Water Unappropriated Water Regulatory Demand

4. Envision Water Master Terminology Available Water (stream or well) IDU water demand (crop and/or municipal) Allocated Water Unappropriated Water Minimum flow Appropriated water (pod rate) Unexercised Water Right

5. Envision Water Master Terminology Available Water (stream or well) IDU water demand (crop and/or municipal) Allocated Water Unallocated Water Minimum flow OWRD POD rate Runtime (Assert)

6. Envision Water Master Terminology Available Water (stream or well) IDU water demand (crop and/or municipal) Allocated Water Minimum flow Unsatisfied demand

7. Summation of daily Irrigation rates for 2011

8. Daily irrigation rate (WW2100 study area m 3 /sec) Other variables for daily water use per IDU: - Number of IDUs -Area of IDUs -Use (irrigation, municipal) -Source of diversion (well or stream)

9. Envision Water Master Terminology IDU water demand (crop and/or municipal) Unavailable Water Minimum flow Water Right Shut Off (log conflict metrics)

10. Water right (WR) conflict and shut-offs (measured in number of WRs, areas, and diversion rates) Sunday Monday Tuesday Wednesday Thursday Friday Saturday X – is defined at run time to explore different scenarios X Level 1 Conflict Sunday Monday Tuesday Wednesday Thursday Friday Saturday X Level 2 Conflict (consecutive days) X Or (consecutive weeks) Sunday Monday Tuesday Wednesday Thursday Friday Saturday X X 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

13. 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)
