- The reservoir has a surface area of 60 square km
- Normal high water level 108 m mean sea level and during dry season 106 m MSL
- EGAT build Pak Mun dam completed since 1994

Stakeholders
Interest in project (positive/negative)
Influence on the project
1. Farmers (fish, rice, vegetable)
(known as the assembly of the poor)
+ An increase in availability of Mekong fish in their fishing areas during the sluice closure
- The fluctuation of water level affects to the vegetable farming on the bank
- The bank protection makes their lives difficult to go fishing
+ The vote of community
+ Request for the compensation
-Less voice
2. Electricity Generating Authority of Thailand: EGAT
+ Electricity generation to meet the peak of power demand
+ Changing the livelihood standard of the effected villagers
+ Implement the project

12. The problems of people in downstream are:
Fisheries: can’t catch more fish because they close the gate so fish can’t migration.
Agriculture:
- people don’t have enough food and income for their life.
they decide to work in the town.
people can’t plant vegetable along the Mun River because bank protection method from EGAT
water quality (the first 3 years)
Social live: decrease of social unity (some of people in village went to controversial with GOV, the other didn’t go the complain people who went to controversial so people not unite like in the past)

13. Downstream Impact from Pak Mun Dam
Before
After
Water availability
-water level
-water quality
Fish
20 box/day
Ex: Pa e tou (fish’s name) there are a lot in the Mun river
0.5 box/day
Don’t have Pa e tou
Production
-Rice
- cassava -
Sifting cultivation or rice field
Can’t do because no labor
(their son/daughters go to work in the town)
Source of fish and period of time to catch fish
Can go any time and got many fish
When the gate opened they will go for catch fish

14. Downstream Impact from Pak Mun Dam
Before
After
Income
fish
Rice
Cassava
Max 100,000 bath/year
Min 30,000-40,000bath/y
Enough for eating in the household
3,000-4,000 bath/y
Max 10,000 bath/year
Min bath/y
They can catch a lot of fish that from Mekong river but just short time not enough.
Just buy
Households(HHs)
12 HHs
12+10= 22 HH
Move from other villages:34 HHs
Total: 56 HHs
Infrastructures
road
temple
public media
Road
1 temple
Don’t have
Road develop by Tourism Authority not develop by dam.
Improved but have only 2 monks
-Increase number of restaurants and shop.
-increase TV, mobile
-Change culture

15. Lesson Learn
People in that area experience on building dam. There are a lot affects on their life. They don’t want dam at all.
A lot of negative effect has been found e.g. fisheries
Unbalance between cost and benefit (cost high but benefit low)
stakeholder related resources must be concerns while planning.

16. Recommendations Dam must be open at least 6 months
Find new method for protect river bank
An anonymous source suggested that the dam should be named according to the name of Royal Family, e.g. Sirindhorn Dam
