  1. How Idaho Is Bringing Water Rights Accounting Into the 21st Century Tony MorseIdaho Department of Water Resources Beck diagram of the Snake River model

  2. Surface Water Users SueManagement of Water in Idaho in Dispute By Michelle DunlopTimes-News writer BOISE - The floodgates have opened, and litigation - not water - will soon pour out…. --Twin Falls Times News, 8/28/2005

  3. Water Rights Accounting FORTRAN DEC platform Closed process Computer model ca. 1970 Five major river basins modeled Most of Idaho’s surface water irrigation. Don’t Laugh…

  4. Accounting Basins Payette Boise Big Lost Snake Bear

  5. Water Rights Accounting Computes natural flow and storage Daily basis For each POD (group of water rights) Used by Water Masters Used to determine reservoir releases Used to determine annual carry-over.

  6. Motivation for Change Personnel retirement Conjunctive management Transparency in processing Modeling needs modern IT tools GIS RDBMS Internet Access Software and data standards.

  7. Project Goal Make water rights accounting an open application.

  8. Project Objectives • Redesign and upgrade the current water rights accounting models into a modular and integrated GIS environment 2. Simplify the multiple-step modeling process, and integrate tools for data visualization and plotting 3. Make model data and results accessible over the Internet.

  9. Major Changes PC platform GIS and Remote Sensing Based on the NHD ArcHydro and custom tools Data handling with RDBMS (Access) The Internet ArcIMS Display input data and results Reports and custom maps (pdf).

  10. Five Phases • Port Model(s) to PC (don’t touch the FORTRAN) • Display input data and results on the Net • Implement GIS for a front and back end • Move some FORTRAN functions to GIS • Evaluate need for increased functionality In parallel, not series.

  11. The Original Model DEC Alpha Platform Data Manipulation with DCL ASCII Input and Output Files Non-Structured FORTRAN Code.

  12. Problems - Original Model Data Over-Writing Little Error Checking ( e.g. “.” is valid) Inappropriate Functionality in FORTRAN DEC is gone DEC Alpha Platform Data Manipulation with DCL ASCII Input and Output Files Non-Structured FORTRAN Code.

  17. Advantages of New Approach Supported hardware, OS, software Public access to input and results Integration of GIS Spatial tools for spatial data RDBMS for error checking, preprocessing Software and data standards Basically, integration of modern IT tools.

  18. Challenges New personnel Change on the fly Convincing the reluctant Overcoming the step function.

  19. New Personnel Good news and bad news Bad news: steep learning curve Good news: open to new things have good IT skills enthusiasm.

  20. Change on the Fly Modify the model while it is in use Run models in parallel for a full season.

  21. Convincing the Reluctant Incremental change Emphasis on error-checking Change the non-essential first Get the reluctant to convince themselves.
