AKHORI DAM PROJECT
JULY 2023

2. AKHORI DAM PROJECT
Dam site is located near Akhori village across Nandna-kas, a small
tributary of Haro River about 28 Km south east of Attock Town,
Punjab.
Objectives
 Water Storage (7.00 MAF) for supplementing Indus Basin
Irrigation System
 Hydropower Generation (600 MW)
 Flood Mitigation

3. Islamabad to Attock 85 km
Attock to Akhori Dam 28 km

4. WATER AVAILABILITY FOR AKHORI PROJECT
 Analysis for water availability for Akhori Project was carried out
during the study in year 2006 considering the surplus flows of
Indus River downstream Kotri (1976 to 2005)
 Three main storages on Indus River : DBD, Kalabagh and Akhori
were considered along with existing Tarbela
 Six scenarios with various project development sequence were
analyzed based on average year flows
 For all options of project development sequence, water is found
available for Akhori and downstream Kotri

Tasks to be Resolved
 Consensus Among Provinces
 Environmental issues for Reservoir and Conveyance system
 Seepage issues in Reservoir Area
Merits
 Storage available near Irrigation System
 No Sedimentation issue
 Ground water Recharge and surface water availability for nearby
population

12. AKHORI DAM PROJECT – STAKEHOLDERS’ CONSULTATION
STATUS
 Feasibility Study was shared with provinces, comments received in
December 2006 and responded in January 2007.
 Presentation to Punjab held on May 14, 2007. WAPDA requested
Govt. of Sindh on April 28 & June 30, 2007 and Govt. of KP on
May 17, May 27 & June 30, 2007 to allocate time slot for
presentation.
 Due to non allocation of time slot for presentation, a meeting was
held on Dec. 01, 2007 under the chairmanship of Secretary
MoW&P, it was decided that “The Ministry shall convene a meeting
in Islamabad to discuss the observations of provinces on
Feasibility Study of Akhori Dam Project as soon as possible”.
 MoW&P scheduled a meeting on April 30, 2009 to evolve
consensus for the project but the meeting was cancelled.

13.  WAPDA requested Govt. of Punjab on July 11, 2014 to evolve
consensus among provinces on Project Feasibility.
 MoW&P desired information on July 02, 2015 on Water Availability
and Environmental Impacts to satisfy provincial concerns. Report was
submitted on July 16, 2015.
 WAPDA presented Akhori Dam Project to Sec. Irrigation, Govt. of
Punjab on Sept. 16, 2015 and requested to develop consensus
among Provinces.
 WAPDA on January 30, 2018 requested MoWR to arrange a meeting
so that Provinces could be approached for their co-operation in the
national interest.

14. AKHORI DAM PROJECT – WAY FORWARD
MoWR under its mandate may convene a meeting to discuss the
observations of provinces on Feasibility Study of Akhori Dam Project
and evolve consensus among the provinces for taking up the
project.

15. AKHORI DAM PROJECT - STATUS
FEASIBILITY STUDY
 PC-II for Feasibility Study approved by CDWP on March 19, 2004.
 Feasibility Study Report completed in January 2006.
DETAILED ENGINEERING DESIGN
 PC-II for Detailed Engineering Design & Tender Documents
(Rs. 818.00 Million) submitted to MoW&P on June 23, 2006.
 PC-I for land acquisition and resettlement of affectees amounting to
Rs. 67,023 million submitted for approval of ECNEC in April 2006.
 PC-II & PC-I are pending due to non-consensus between the
stakeholders.

STAKEHOLDERS’ OBSERVATIONS & RESPONSE
PUNJAB
Punjab has no objection on the project execution.
BALOCHISTAN
Balochistan has no objection, however, demanded 12% of royalty on
hydropower generation from Akhori on the basis of 12% share in water.
Govt. of Balochistan was requested to approach Federal Government
being competent to decide the matter.

18. # KP OBSERVATIONS RESPONSE
1 Un-favorable geology. Geology is favorable however more
investigations will be carried out during
detailed engineering design stage.
2 Excessive seepage which will ruin their
agriculture fields.
Dam design take care of seepage issue.
Adequate investigations, lab testing and
analysis would ensure dam safety.
3 Location of powerhouse in Punjab due
to which royalty will be claimed by
Punjab whereas the people of KP will be
displaced and their lands will be
affected.
Adequate compensation will be paid to
the displaced persons and their
resettlement will be ensured.
4 Availability of water. Data shows that water is available for
Akhori Dam.
5 Design of the dam is faulty as appearing
in feasibility report.
Detailed engineering design will be taken
only after carrying out geological
investigations & hydrological studies.

STAKEHOLDERS’ OBSERVATIONS & RESPONSE

19. # SINDH OBSERVATIONS RESPONSE
1 Water availability. Ample water is available for the dam
according to data available.
2 Unfavourable geology at the
dam site.
Geology permits the construction of dam.
3 Non-assessment of flows
downstream Kotri in EIA
Studies.
Environmental Impact on downstream Kotri
has been assessed.
4 Deterioration of ground water
quality.
Instead of deteriorating the quality of
ground water; the construction of dam will
improve the ground water quality in Sindh
due to continuous releases from the dam.
5 Seismology of the project area
is not favorable.
Seismological studies show that dam is
feasible at the proposed site.
