• Many of lakes and rivers in our country as well as in the world were polluted by means of several factors degrading the water quality and eventually became impotable.

• Current understanding of water resources management can only be realized by the contribution of

Experts (scientists and engineers)

Stake Holders , and Peoples • These three groups have very

important roles in taking the right decisions about water resources management.

Lakes can form by means of accumulation of waters in depression zones of earth.

Input to Lakes; Precipitation, Surface Runoff, and Groundwater Output from Lakes; Evaporation from lake surface, Streams leaving from lakes, and Seepage to groundwater, etc.

• Lakes have important roles effecting on hydrology, ecology, environment, and socio-economical aspects of their surrounding region.

• Lakes are also important refuges for immigrating birds to rest and nest as well as for aquatic bio-life, flora and fauna to suspend their life.

• Lakes are dynamic regions exposed to all kinds of natural and anthropogenic impacts.

• It is very vital to have consensus among the water managers, land owners, and other related groups with lakes to maintain the biologic diversity and productivity while utilizing the water resources rationally

How Could Be More Successful in Application of the Management Plan?

• A SYSTEMATIC APPROACH SHOULD BE IMPLEMENTED in application of techniques to solve the lake-problems or to rehabilitate the lakes efficiently in problematic areas.

• During application of a surface water resources (such as lakes) management plan, it is very important to have A CERTAIN AUTHORITY that is ACCESIBLE TO ALL INTERESTED GROUPS to get the highest possible efficiency in implementation of project activities.

• A proper lake management plan should:– Require expression of accepted visions,– Have common decisions about the targets and

corresponding activities to reach them, and – Require the partners to know what actions to

implement clearly to rehabilitate the lake. Development of Management Plans are a complex process

that requires; Information-knowledge, Conversation-communication, Participation, Budget, and Support.

• Management plans should be multisectoral and their applications require contribution of people and organizations (World Wildlife Fund, Nature Association, etc).

• Applications of management plans should comprise;

Local governments, National governments, Private businesses and nongovernmental

organizations, and Boundaring countries of a lake.

• Lake should be managed as a whole including its drainage area. Management Plan should clearly present;

The procedures to be followed during the application of management;

Priorities should be defined clearly; Necessary sources should be defined to apply the

plan.

• Lake Eğirdir, one of the most important water resource of Turkey, is located in south-west of Turkey known as “Lakes Region”. The lake is contained in the boundaries of Isparta Province and it has important contributions to the regional economy.

• Lake Eğirdir has a volume of about 4 billion m3 fresh water in the class of oligotrophic waters by having less nutrient and rich oxygen.

• Average depth is about 10-12 meter.

• Lake doesn’t have any thermal stratification due to wind effect.

DESCRIPTION OF THE STUDY AREA: DESCRIPTION OF THE STUDY AREA: LAKE EĞİRDİRLAKE EĞİRDİR

• Maximum water level is 918,96 m and surface area is 487 km2.

• Drainage area is about 3309 km2. • Eğirdir Basin is at the transition zone

between Mediterranean and Central Anatolian dry climate.

• Northern and southern winds are dominant along the year which take important roles in mixing of the lake.

• Average Precipitation; • 748 mm South region • 512 mm Northern region

• There are totally 81 settlements on the basin. 27 municipal district including 5 larger towns in the lake’s basin of which only two of the have wastewater treatment facility. Those lucky ones are Eğirdir and Yalvaç municipalities.

• Luckily there are no major industrial activity around Lake.

• Up to now, because of its good quality water, Lake Eğirdir has been used for;

drinking and irrigation water supply,

fishing, tourism and hydro-electric energy

production.

• In recent years, some signs of water quality degradation in the lake have come up indicating that the water quality of the lake has already started to decline. These emergency signals have forced us to develop this LAKE EĞİRDİR MANAGEMENT PLAN.LAKE EĞİRDİR MANAGEMENT PLAN.

IMPORTANT DATES OF THE MANAGEMENT PLAN

Starting date: 09 November, 2006Ending Date: 03 January 2008Approval Date: 27 March 2008by National Wetlands Commission

• Under the coordination of Environment and Forestry Directorate of City the following groups took part in preparation of the MANAGEMENT PLAN:

Agricultural Directorate of City, 18th Regional Directorate of General Directorate of State Hydraulic Works (DSİ), Cultural and Tourism Directorate of City, Eğirdir Municipality and Head official of Eğirdir town, Eğirdir Aquacultural Research Institute and Süleyman Demirel University (Agricultural Faculty, Dept. of Environmental Eng., Forestry Faculty, Eğirdir Aquacultural Faculty, Dept. of Biological Science).

• Firstly, local people and governmental agencies were informed about Lake and Lake Management Plan.

• Target groups are selected as people living around the lake, leaders of villages, fisherman and irrigation cooperations in this educational reach out studies.

• Experts in the study group performed, Survey (questinaires) Studies, Zoning studies, Water sampling and analysis studies.

And finally the ideal objectives of the management plan are determined in six main title;

1. to decrease the pollution in the lake, 2. to sustain fishing, 3. to sustain tourism as eco-tourism, 4. to sustain agriculture and livestock production

around the lake in an optimum level, 5. to sustain wild life and forest eco-system around the

lake, and 6. to share the information about lake basin

APPLICATION OF THE MANAGEMENT PLANAPPLICATION OF THE MANAGEMENT PLAN• After preparing the management plan, Local

Wetland Commission were met on 01 May, 2008. • In that meeting the following decisions were taken:Establishment of a legal entity, A budget

To found EKOBİR EKOBİR (Eğirdir-Kovada Lakes (Eğirdir-Kovada Lakes Environmental Protection Alliance) Environmental Protection Alliance) to enable contribution to the Lake Management Plan

• Some of the activities determined to reach the ideal targets were set to hold for the timebeing because of the following reasons:

Insufficient funding of EKOBİR which is the Insufficient funding of EKOBİR which is the

coordination agency in Lake Management.coordination agency in Lake Management.Lack of coordination, and ”Special Ruling DeterminationSpecial Ruling Determination”” study study which

was originally intended a parallel study to the management plan could not completed yet.

• When evaluated “Lake Eğirdir Management Plan” as of today; 42 out of 49 actions to achieve 6 ideal targets determined in the plan have been implemented successfully. This means completion ratio is 86% which shows how realistic the management plan was.

Conclusion:• If “THIS MANAGEMENT PLAN”

had been started to be developed today, establishment of Lake Management Authority “EKOBİR” would have been speeded up so that some of the planned activities that was delayed due to lack of funding and coordination would not be happened.
