The purpose of this activity is to provoke participants to discuss more adaptive Colorado River operations than existing operations that equalize reservoirs and expire in 2026. Participants use a Google Sheet to consume, save, and trade water in 6 basin accounts, protect Lake Powell and Lake Mead, sustain endangered, native fish of the Grand Canyon, and discuss. Follow the requirements and facilitation directions in the readme.md file.
1) readme.md - Requirements, facilitation directions, publications, file contents, and more.
2) Basin Accounts Tool - ColoradoRiverBasinAccounts.xlsx. Move into Google Sheets and follow Facilitation Directions (in readme.md). Or open ReadMe-Directions Worksheet.
3) Lets Start - ColoradoRiverBasinAccounts-LetsStart.pdf. Visual directions.
4) Model Guide - https://github.com/dzeke/ColoradoRiverCoding/blob/main/ModelMusings/Support/ModelGuide/ModelGuide-CombinedLakePowellLakeMead.md. Online.
5) Manuscript - 3-LessonsRealTimeOnlineModelingToDiscussMoreAdaptableReservoirOperations.docx. Write up for publication as a journal article. Earlier cite-able version at https://digitalcommons.usu.edu/cee_facpub/3778/.

The purpose of this activity is to discuss more adaptive Colorado River operations than existing operations that equalize reservoirs and expire in 2026. To provoke discussion, download the Excel Model File (ColoradoRiverBasinAccounts.xlsx), move to Google Sheets, and invite participants. There are accounts for the Upper Basin, Lower Basin, Mexico, Colorado River Delta, First Nations, and a shared reserve. Over one or more years, participants consume, save, and trade water in the accounts, protect reservoirs, and sustain endangered, native fish of the Grand Canyon. Read on for directions to use.
Facilitator: 1 person to setup in Google Sheets (see Setup below), invite participants, and organize play.
Number of People: 2 or more (facilitator may also participate).
Time: 1 to 3 hours.
Software: Facilitator has a Google Account.
Download the file ColoradoRiverBasinAccounts.xlsx to your computer.
Move the Excel file to your Google Drive. Open as a Google Sheet.
Open the Versions Worksheet to see updates.
Duplicate the Master Worksheet to save a blank version for later use.
Invite 1 or more other people to join the Google Sheet.
In the upper right of the Google Sheet, click the Share button.
Add emails, and set permissions so players can access the Google Sheet. Or copy and share the sheet's URL.
On the Master Worksheet, scroll down Column A. Participants enter values in rows with 🟦
For example, in Rows 4-10, particants select a Account and enter a Strategy. If fewer than 6 participants, participants select multiple parties.
Enter the Lake Powell natural flow for Year 1 in 🟩
Cell C28. Cells below will populate.
Participants continue to enter values in Year 1 (Column C) down to Row 142 in row blocks with 🟦
Move to Year 2 (Column D). Enter Lake Powell natural flow in 🟩
Find linked help for each row in 🟨
View the Master-Plots worksheet to compare entries to current operations (Law of River).
ReadMe-Directions Worksheet also has these directions and describes all worksheets in the Workbook.
