A risk-based decision-making
game relevant to water
management.
Try it yourself!
2013. This game was prepared by Louise Crochemore (IRSTEA), Florian Pappenberger (ECMWF),
Schalk Jan van Andel (UNESCO-IHE), Maria-Helena Ramos (IRSTEA) and Andy Wood (NOAA).
If you use this game, the authors would be grateful for feedback on your usage and results so as to
help improve future versions of the game and justify further development efforts. Special thanks to

You are the newly appointed water manager for Lake Dual
It is a reservoir that serves two primary functions:
1. Water supply for Swof Town
2. Flood control for Safe Town

Water management game: instructions
1. Swof Town: would like to see the reservoir full on August 1st (500 Mm3)
so that its residents can count on water all summer.
2. Safe Town: residents are interested in keeping releases below 60 Mm3
each month (anything more causes flood damage to their homes)

Water management game: instructions
You are going to be the water manager for Lake Dual during the season
running from April to August:
- you will be presented with probabilistic forecasts of inflows, and
- at the beginning of each month you have to decide on the reservoir
releases for the remaining months.

Water management game: remember!
your aim is to have the reservoir level as close as possible to 500 Mm3 on
August 1st, but you can never exceed this level.
You have to maintain a minimum release of 15 Mm3 for environmental flow and
your maximum release cannot exceed 60 Mm3.
If you fail to meet these constraints, you will be fired! The WINNER of the game is
the manager that has the highest level on August 1st (but < 500 Mm3)

April has gone by.
April inflow was: 18 Mm3
You can update your reservoir volume:
The volume on May 1st is:

April has gone by.
April inflow was: 18 Mm3
Our volunteer’s April release was: 37 Mm3
The volume on May 1st is therefore:

June inflow was: 120 Mm3
You can update your reservoir volume:
The volume on July 1st is:

June has gone by.

April has gone by.
April inflow was: 18 Mm3
You can update your reservoir volume:
The volume on May 1st is:
April 1 volume + 18 Mm3 - April release = ?
Did you overtop your reservoir?
