Introduction

This guidelines focuses on the construction and operation of dams and reservoirs for

various purposes. They highlight major issues and potential impacts that should be

taken into account during the preparation and assessment phases. The appropriate

enhancement and mitigation measures should be integrated as early as possible,

preferably in the project design.

1. Major Types of Intervention in the Dams and Reservoirs Sub-
Sector

The construction and operation of dams and reservoirs include several activities or

components that can potentially induce significant environmental and social impacts:

 River diversion, including the construction of diversion canals.

 Land clearing and relocation/demolition of existing infrastructures in the future

reservoir.

 Construction of secondary dykes.

 Population resettlement.

 Construction of access roads.

 Construction, maintenance and closure of labour camps and other temporary in-

frastructures.

 Construction of the dam: digging, blasting, construction of foundations, transport-

ation and storage of material, operation of heavy machinery, etc.

 Exploitation of borrow pits (on-site and off-site).


2. Specific Characteristics of Dams and Reservoirs Projects

The description and justification of a hydropower project shall cover at least the fol-
lowing elements:

 Spatial requirements (reservoir and dam area as well as other sites required for
works).

 Project layout characteristics (including site location map).

 Land tenure and ownership.

 Affected groups (directly or indirectly).

 Resettlement requirements and proposed transition and compensation means.

dredging, filling, compacting, waterways crossing, use of heavy machinery, etc.).

 Anticipated liquid, solid (including waste) and gaseous emissions, and sources of
nuisances (at construction and operation stages).

 Construction schedules and costs.

 Management and operation of the dam and reservoir (water flow, minimum flow
requirements, anticipated sedimentation and proliferation of aquatic plants, etc.).

The potential impacts outlined below are presented by crosscutting theme (one table per theme) to clearly identify the potential in -

teractions between a dam and reservoir project and a specific transversal issue. The components considered under each crosscut -

ting theme were selected for their relevance to the particular issue.

4.1 Poverty

Component Potential Beneficial and Adverse Impacts Enhancement and Mitigation Measures

Economy  Increase in economic activity and employment.
 Induced development due to new opportunities

such as in fisheries and dam related projects (irrig-
ation, hydropower, etc.)

 Disruption of existing activities particularly flood-
plain agriculture and artisanal fisheries down-
stream.

cultivating the land in the flooded areas.

 Disruption of activities in catchment areas, partic-
ularly if they represent potential sources of pollu-
tion for the reservoir.

 Benefits not accessible to people adversely af-
fected by the project.

 Give preference to local employment (men and women) and local inputs (food, ba-
sic material) to the extent possible.

 Offer appropriate compensations or alternative income opportunities to men and
women having a reduced access to or loosing productive means.

 Ensure that the poor and other vulnerable groups can continue to safely satisfy
their basic needs.

4.2 Environment

Component Potential Beneficial and Adverse Impacts Enhancement and Mitigation Measures

Air  Degradation of air quality by dust, heavy ma-
chinery atmospheric emissions and waste dis-
posal.

 Increase in ambient noise during construction.

 Install and operate air pollution control equipment.
 Near the residential areas, avoid noisy works after regular working hours.

ridors in order to minimise noise and the aerial transport of dust.

Water  Flood control.
 Interruption of surface water flows during and

after construction.
 Changes in the level of groundwater table result-

ing from changes in the drainage and water flow.
 Contamination of surface and underground wa-

ters by wastewater and hazardous materials.

downstream impairing dam discharge, irrigation
schemes, navigation and fisheries.

 Degradation of the reservoir water quality.
 Salt-water intrusion in estuary and upstream.

 Do not hamper drainage of surface water and plan for restoration measures after
construction.

 Plan and set up on-site sanitary facilities for the disposal of wastewater.
 Maintain vehicles, machinery and equipment in good condition in order to avoid

leaks and spill of hazardous materials (hydrocarbons, chemical products, etc.).
 Ensure a safe management of hazardous materials (hydrocarbons, chemical

products, etc.).
 Take all precautions during the refuelling of vehicles and machinery, and forbid

the refuelling near water bodies.
 Avoid crossing permanent waterways; if necessary, locate the crossing where the

banks are stable and the waterway the most narrow.
 Conserve the vegetation along water bodies and near wetlands.
 Plan emergency response measures in case of accidental spill.
 Assess the relevance of clearing the vegetation before flooding the reservoir.
 Apply appropriate weed control measures.
 Control land uses, wastewater discharge and agricultural chemical inputs in wa-

tershed.
 Limit retention time of water in reservoir.

roads perpendicularly or diagonally to the slope.
 Use existing borrow pits rather than creating new ones; after the works, restore

borrow pits by stabilising slopes and facilitating vegetation regeneration.
 Stabilise the soils in order to reduce potential erosion.
 At the end of construction works, level off the soils and facilitate vegetation re-

generation.
 Implement integrated watershed management in order to control soil erosion.
 Prevent land clearing in watershed and facilitate the reforestation of cleared

areas.

lands and unique habitats sheltering endangered species.
 Minimise the length of work in ecologically sensitive areas.
 Avoid flooding wetlands and protected areas.

Flora  Destruction of vegetation.
 Loss of forest products (fuel wood, timber, non-

timber forest products, medicinal plants).
 Bio-accumulation of methyl mercury in the tis-

sues of fish-eating wildlife species, affecting their
vital organs and central nervous system, especially
in acid and anaerobic conditions.

 Minimise the land clearing areas around the reservoir.
 Recuperate the forest products extracted from land clearing and identify mechan-

isms to distribute the products to the local population.
 In regions where conditions can favour mercury methylation, remove as much as

possible the vegetation and organic matter on the ground before flooding, and
manage the reservoir to minimise methyl mercury production (e.g. gradual flooding,
reduced water retention time, etc.)

Dams and Reservoirs Guidelines, FEPA, 2004 14


5. External Factors

The following external factors may significantly reduce the benefits associated with a

dam and reservoir project, and even jeopardise its success:

 Poor land use practices

Poor land use practices in the watershed, such as deforestation, can result in in-

creased sedimentation in the reservoir and changes in water quality. Integrated wa-

tershed management, addressing all land uses in the watershed, can help to mitigate

such problems.

 Earthquake

Some evidence demonstrates a link between the creation of a reservoir and earth-

quakes in seismic areas. Indeed, a reservoir may advance in such areas the occur-

rence of an earthquake, possibly resulting in more frequent but less destructive

events (World Bank, 1991).

 Immigration

The venue of migrants attracted by new economic opportunities such as fisheries

can generate several problems like overexploitation of natural resources, social con-

flicts and increased health risks. The appropriate planning of human settlements and

social services to respond to additional needs can reduce problems associated with

immigration.

 Social Instability


6. Hazard Management

The main hazards associated with a dam and reservoir project are:

 Dam rupture, causing sudden flooding of the downstream area and resulting in

the loss of human lives and serious economic damages.

 Health hazard such as drowning and injury due to unpredictable draw down and

downstream flow rate fluctuation.

In order to prevent or minimise these hazards, appropriate risk management meas-

ures shall be designed and implemented.


7. Environmental and Social Monitoring
