HOW TO SAVE LAKE URMIA IN HOW TO SAVE LAKE URMIA IN ISLAMIC REPUBLIC OF IRAN?ISLAMIC REPUBLIC OF IRAN?
Lake Urmia is endorheic salt lake in northwestern Iran. It is the largest lake in the Middle East and the sixth-largest salt lake in the world. Its surface area is about 5,200 km2, and its deepest part - 16 m.
The lake is divided into northern and southern parts by a causeway, having a weak water exchange between them.
Due to drought and increased demand for water for agriculture in the Lake basin, the lake water salinity in recent years has risen to over 400 g/L, and a large area of the lake dried out.
Since 1967 Lake Urmia has the status of a protected wetland.

Lake Urmia and its catchment area are located in the northwest of the Islamic Republic of Iran.
The total catchment area reaches 51,800 km2. Super-saturation has converted Lake Urmia
into the most saline lake in the world.The catchment area belongs to three
provinces: West Azerbaijan, East Azerbaijan and Kurdistan.
The catchment area of Lake Urmia can be divided into 14 sub-basins.
The smallest of them has an area of only 431 km2, and the largest – 11,759 km2.
The catchment area includes 14 river systems.
In East Azerbaijan watersheds located catchment areas of 5 rivers: the upper reaches before the dam and the lower reaches after the dam of river Aji Chai;the upper reaches before the dam and the lower reaches after the dam of river Sofi Chai.
Here there are catchment areas of more three rivers:Ghaleh Chai, Mardogh Chai, Leilan Chai.
In West Azerbaijan watersheds located catchment areas of 9 rivers: the lower reaches after the dam of the river Zarrineh Rood;the upper reaches before the dam and the lower reaches after the dam of river Mahabad.
Here there are 7 catchment areas of rivers: Shahr Chai, Simineh Rood, Gedar, Barandooz Chai, Rozeh Chai, Nazloo Chai, Zoola Chai.
In Kurdistan there is just upper reaches of river before the dam Zarrineh Rood.
It should be noted that there are only three large rivers:
1)Zarrineh Rood which in Persian means Golden River, is the main source of fresh water for Lake Urmia. It provides more than 50% of annual runoff. This river flows through the two provinces – Kurdistan and West Azerbaijan. Its length is 302 km, and it begins in the mountains of Kurdistan province. Zarrineh Rood flows to the north and is dammed on the frontier with the West Azerbaijan. This dam is hydroelectric and forms a reservoir on the river. After the dam the river continues to flow to the north, turning slightly to the west, and passes through the city of Shahin Dezh, Kashavar, Miandoab and flows into Lake Urmia.
2) Simineh Rood flows parallel to Zarrine Rood and Gadar. It provides about 15% of annual runoff. These two parallel rivers bring into Lake Urmia only 25% of river flow (Mohaggeg, 2002). There is no dam on Simineh Rood and its water flows directly to Lake Urmia.
3) Aji Chai is also relatively large river, it is a salty river and brings consideable amount of salt to Lake Urmia. It provides about 10% of the annual runoff.

In November 2008 – February 2009 from 25 points in the Urmia Lake wetlands a total of 32 taxa were collected, and the common taxa, including Chironomidae (midges), Corixidae (water boatmen), Erythemis (damselflies), Ephemerella (mayflies), Hyalella (amphipods), and snails. Samples at ponds with salinities greater than 10 ppt showed a shift in community composition to salt-tolerant taxa and a reduction in total diversity. The corixid Trichocorixa verticalis, the brine shrimp Artemia partenogenetica, and the dipteran Ephydra are salt-tolerant species that only occur at high salinity levels. Ponds relatively high in nutrients had fewer total taxa, reduced abundance and diversity of aquatic beetles, lower diversity index values, and a greater dominance by chironomids than ponds low in nutrients. It is suggested to allocate about 10 ×106 cubic meters freshwater of the represented rivers to these wetlands to improve their trophic condition and transfer their hypereutrophic waters into the Urmia Lake for more production of the macro invertebrates both in the wetlands and on the lake.

How the Lake Urmia dried so rapidly?
02.04.2013 22.09.2014
Rapid desiccation in less than 18 months
08.10.2014
How 3 days raining affected
the lake level
The surface area after 3 days
raining (80 mm) increased by
about 2.5 times
How this is possible?
22.09.2014
That is how the Lake Urmia is converted into a small shallow playa
In just 20 years
Lake Urmia is a shallow lake with huge surface area permitting evaporation of about 4 bm3 water annually
Lets have a look to some specific and very important characteristics of the Lake
Urmia:
Depth, Water volume, salt content and evaporation
Sharifi, 20023 dimensional view of the Lake Urmia in 2002 (6 years after commencement of the crisis) showing deep areas in North and South wingsWater level: 1273.27 masl
Deepest parts: 16 mAverage depth: 6 m
What has happened to the deep areas of the Lake?
Decrease in water level since 1995 (7.19 m)
Urmia Lake water level before crisis 1277.69 masl
Deepest part should be 16-7.19=8.81 m
Current water level 1270.50
Current maximum depth: 3 m
It seems we have not lost 7.19 m water but the depth has reduced by 13 m
Urmia Lake water level before crisis: 1277.69 masl
Annual evaporation and consequent salt/minerals sedimentation added layer on layer to fill the deep parts
causing significant changes in geomorphology of the lake
Current water level: 1270.50 masl
Lake salinity before crisis: 160 pptAmount of salt in Lake water: 33 bm3 * 160 kg = 5,280,000,000 tons Where the salt has
gone?
Minerals are sedimented mostly in deep zones
Changed geomorphlology is the reason for vast annual filling and rapid evaporation
Natural joining of Gadar, Mahabad and Simineh Rivers
This process is repeated every year
leaving behind another layer of salt/sand/clay
sediments on the lake bed
Simulations of the annual natural happenings

Changed geomorphology of the
lake will practically neutralize any
effort for its restoration; unless we
understand the real mechanism to
overcome this problem.
WHAT TO DO?
Urmia Lake water level before crisis
What will happen if we bring annually 3 bm3 of fresh water through rivers or brackish water from Caspian Sea?
but more than 2 bm3 will evaporate leaving behind another layer of salt on top of previous sedimented salts
4000 km2 area of the lake will be covered with average depth less than 1m
Knowing about the extremely flat bed of the Lake, it seems it would be a senseless practice to pour precious water in the lake to evaporate
Moreover we know that we will not have enough fresh water to maintain the level of the lake in future, due to population growth and further industrialization
So What to Do?
We believe that Phased Restoration is the only solution to overcome all problems preventing the restoration of the lake
Our plan is based on sustainable management and wise use of the lake both for its natural inhabitants and for the people living in its vicinity.
There are 2 options for reducing surface evaporation and restoration of Lake Urmia
1. Restoring the South Arm first (due to its ecological importance) and keeping the North wet.
OR
2. Restoring the North Arm and keeping the South wet, it is easier because there is about 1 km3 water in North.
We propose a simple and efficient solution for this problem which seems to be the most reliable method for saving Lake Urmia
By dividing the lake to north and south by a temporary easy removable metal or polyethylene dike
Option 1: Restoring South Arm First
1. Constructing a dike (Clay dike covered with geomembrane) cutting the South arm in 2 parts from under the large islands with 3 spillways.
2. Connecting the 3 islands with dikes.3. Filling the area between the islands to
restore a 8000 ha with controlled salinity for Artemia and birds.
4. Filling another 1900 km2 in South arm between south dike and the dike under the bridge and the (average depth 2.2 m).
5. Keeping the north arm wet (to control salt storm) until we have enough water to fill it.
This Phased Restoration at the level of 1272 masl will need in total less than 8 km3 water.
Option 2: Restoring North Arm First
• Separating North Arm from South by an easy removable dike under the bridge connecting 2 arms
• Water that runs up to the bridge (dike) naturally should be pumped to the North arm filling an area of 1500 km2 at an average depth of 2.2 m within maximum 3 years
• During this period we can keep the South arm wet with little water due to its vary flat surface (to control the salt storm)

Joining of Gadar, Mahabad and Simineh Rivers
What type of dikes are preferred?
• Polyethylene dikes• Geomembrane
dikes• Clay Dikes• Sand and stone
dikes• Concrete dikes• Metal dike
We should find out which one best fits for Lake Urmia
Restoration in Phases:
Phase 1: Restoration of a natural ecosystem between big islands in South wing (8000 h) for Artemia and Birds, water salinity will be adjusted at about 100 ppt
Phase 2: Restoring another 1900 km2, 2.2 m deep in South arm as main water body of the lake, salinity will depend on volume of water and dissolution of salts
Phase 3: Restoring North arm (1500 km2, 2.2 m deep) if there is enough excess water after restoration of the South arm, salinity will always remain supersaturated
This method will require a total of less than 8 bkm3 of water for restoring Lake Urmia
This project will ensure the earlier safe place for migrating and local birds
Safe living will be once again ensured for the mammals in Ashk and Kabudan islands
Artemia resources will be revived, that will create hundreds of job for young and will support the aquaculture industry to grow sharply
Six pillars of “ILBM Pavilion”
1. Institutions. A management system with an appropriate organizational setup helps ensure sustainable benefits to lake basin resource users. Such institutions are in Lake Urmia basin.
2. Policies. Policy tools must be better developed to facilitate concerted societal actions for sustainable lake basin management. Such policies are in Lake Urmia basin.
3. Participation. All lake basin stakeholders should participate in decision-making process for sustainable management. Such participation are in Lake Urmia basin.
4. Technology. Although their effect often tend to be limited by certain areas and short period of time, physical interventions can play a significant role in improving lake environment. Some of such technologies are available in Lake Urmia basin.
5. Information. Scientific and public perceptions on lake basin management can differ from case to case. Without knowledge generation and sharing, human and financial resources mobilized in lake basin management efforts may prove futile. Such information are available in Lake Urmia basin.
6. Finance. Financial resources should come from all basin stakeholders benefiting from both direct and indirect use of lake resources. Efforts must be made in order to develop innovative approaches for generating locally-usable funds. Such financing is possible in Lake Urmia basin.
Based on many years of successful work on the lakes and reservoirs in various countries ILEC (International Lake Environment Committee Foundation) formulated ILBM platform (integrated lake basins management). ILBM platform is based on the basic management principles:
1. Engaging in the conservation and rational use of resources of lakes and reservoirs:
a) politicians and political forces at all levels; b) scientists and scientific institutions at all levels;c) all social groups with their mandatory participation in the planned
environmental protection measures;d) the most modern information resources, ensuring timely exchange
of information, the maximum openness and transparency in the implementation of planned environmental protection measures, full transparency and punishment when it detects any errors;
e) required volume of finance, use of innovative financial mechanisms, establishment of public and private funds, control and maximum transparency in the use of funds, full transparency and punishment upon detection of any violations.
2. Using modern technologies and the best practices in the implementation of environmental measures for conservation and sustainable use of resources of lakes and reservoirs.
On the basis of these steps Lake Urmia can be at least partially revived and sustainable use of its resources ensured.
