Goal Definitions

Goal #1. Increase the Idagon Economic Product by 5%
The Idagon Economic Product (IEP) is the principal economic indicator. It counts net income from crop production and electric power production. In most simulations, the IEP will be around $1,000 million per year. It is nearly a "Billion Dollar" system. The goal is to boost the IEP to $1,050 million per year.

Goal #2. Maintain Land Use Patterns in Areas 1 & 2 at 95% of Historical Value
Historically, one million acres of land has been irrigated by diversions (Area 1) and by pumping (Area 2) in the eastern region. This activity has given rise to the development of support industries as well as to towns and villages. These activities are valued in their own right (ie, separate from the contribution of crop production to the IEP.) Consequently, an additional goal is established--to maintain at least 95% of the land in both areas under irrigation.

Goals #3. Achieve 68 MAF/Year Flow in April to Help Salmon
The third goal is to achieve a rate of flow of 68 MAF/year through the section of The Idagon after the Big Fish during April. This flow is considered important to aid the salmon smolts in their spring migration. This flow is highlighted within a box in the report entitled "Idagon Map with Flows."

Goal #4. Maintain Minimum Flow Below Canyon Lake to 4 MAF/Year
The fourth goal concerns the section of The Idagon immediately below Canyon Lake. It is considered important for water quality, for wildlife and for recreation to maintain at least 4 MAF/year of flow in this section during all months of the year.

Goal #5. Maintain Discharge Flow at Big Springs at 9 MAF/year
Historians tell us the discharge was around 6 MAF/year one hundred years ago. But the flow is now around 10 MAF/year, and this high flow is important for water quality, for wildlife and for industries that have developed below Big Springs. The fifth goal is to maintain the discharge flow at 9 MAF/year or greater.

Goal #6. Maintain Minimum Flow below American Lake at 3 MAF/year
The final goal concerns the section of The Idagon immediately below American Lake. It is considered important for water quality, for wildlife and for recreation to maintain at least 3 MAF/year of flow in this section during all months of the year.

The six goals (listed above) have been established for the Idagon. There is considerable disagreement about the relative importance of each of these goals. You are free to define your own priorities by the "weights" you attach to each of the six goals. The default "weights" are:

#1: 3
#2: 2
#3: 2
#4: 1
#5: 1
#6: 1

This arrangement implies that the first goal is 3 times more important than goals 4,5, and 6. You may set your own weights, buy you should check that the "weights" add up to 10. This will allow you to compare scores with others who are experimenting with the model.

The Score Keeper

To check whether you are meeting the goals during any month of a simulation, you may open the "Score Keeper Report." You will earn 1 point per month for each of the goals. The model uses your own weights to calculate a weighted score. Since the weights must add up to 10, the maximum score is 10 points per month or 120 points per year with one exception -- the salmon smolts.

The salmon smolts goal can only be measured in April, the month when the smolts need a high flow in The Idagon after its confluence with the Big Fish. If you meet the April flow target, the Score Keeper will assign all 12 points for this particular goal in the month of April.

To check how your points are accumulating over time, you may open the "Score_Keeper" graph at any time during the simulation. The graph will show this month's score along with the accumulated score for the entire simulation. "Spikes" will appear in this graph if you happen to meet the flow target for April for the salmon smolts.
