Oroklini lake, Larnaca
Oroklini lake is a waterbody located close to the south coast of Cyprus next to the city of Larnaca and within the boundaries of Oroklini village. The waterbody has been subject to modifications and degradation by implementing hydraulic measures in the mid 40’s, in order to desiccate the lake, due to health concerns. The purpose of NWRM implementation was to increase water retention and restore the wetland habitats in order to meet the needs of two important bird species, but also to increase biodiversity. The measures included among others, retention measures aiming at securing water availability in the upper basin of the lake and measures aiming at increasing the biodiversity of the ecosystem.

Performance impact estimation method
Performance impact estimation information
A monthly water operation study of the Oroklini Lake, under scenarios of drought, average and wet conditions was carried out on the basis of the hydro-climatological conditions of the years 1968 to 2011. This was used to evaluate impact on fauna.

Basis of design
Constraints are: urbanization of the area surrounding the lake and demand for new road crossings. Similarly, the urbanization and lack of sewage network causes deterioration of quality of surface water, and future changes of its quantity.
The lowland features of the area and its location favorable to certain bird species and the presence of surface runoff as well as the state ownership of the area are excellent preconditions.

Lessons, risks, implications...
Proper water management with small scale measures can restore wetlands within urban areas for furthering nature conservation objectives such as wet grassland conditions for breeding rare birds. This at the same time may offer minor flood protection.

Policy, general governance and design targets
The NWRM, a water retaining structure with sluice and other water management works, channels for ideal nesting habitat, new low bunds with overflow etc., all tending to prevent the drying out of the lake and fit the needs of the target species.

Policy requirement directive
Direct benefits information
Continuation of the wetland effectiveness within the encroaching urban development. Existence of wetland and nesting ground of two species of birds listed in Annex I of EU Directive. Availability of wet conditions for the period required
Ancillary benefits information
Leisure area within an urban environment. Tourist attraction. Educational area for young people.
Costs investment information
The measure exists only partly. On going studies aim to design in full the NWRM and management of the wetland. Full capital cost is still not known
Costs operational information
The costs will be known once the full management plan including necessary monitoring is established. These might involve analyses of water, fauna observations, assistant†™s visit to check water level recorder and other installations.
Costs maintenance information
Expenses will be identified after completion of NWRM design. Additional costs will involve protection of quality of water flowing to the wetland due to urbanization and encroachment of urban development.
Costs total information
The measure is under study. The full investment will be evaluated after the completion of all relevant studies
Economic costs additional
Ecosystem improved biodiversity
Information on Ecosystem improved biodiversity
The conditions in the area where two very important birds included in Annex I of EU Directive on Birds (Vanellus spinosus and Himantopus himantopus) nest, are greatly improved. The lake hosts some 186 kinds of which 69 are included in the Directive.
Ecosystem provisioning services
Information on Ecosystem provisioning services
The NWRM helps the development of mild tourism activity and leisure activities in agreement with the maintenance of the environmental values of the wetland and the protection of the bird species using it.
Ecosystem impact climate regulation
No specific impact
Information on Ecosystem impact climate regulation
Very minor impact might be expected on climate regulation.
Retained water unit
Information on retained water
In an average year the lake created by the dam is dry in June, July, August and September. The lake is full for the rest of the months except of May (nearly half full) and October (nearly full). Spills maintain wetlands downstream the dam
Increased water storage
Increased water storage unit
Information on increased water storage
The water stored in the lake created by the retention dam in an average year is 0,017 million m3 per month. The wetland collected certain, reduced, quantities of water for some periods of the year which soon evaporated
Runoff reduction unit
Information on runoff reduction
The average monthly water reduction by the NWRM is estimated to be of the order of 6600 m3. The control could be higher if the controlled releases to the downstream wetlands are considered.
Ecosystem erosion control
Information on Ecosystem erosion control
Although of minor impact. Sediments are deposited upstream the dam.
Water quality overall improvements
Positive impact-WQ improvement
Information on Water quality overall improvements
The presence of stored water reduces the salinity of the water
Soil quality overall soil improvements
Neutral impact-no change in SQ status
Information on Soil quality overall soil improvements
No impact on soil quality is observed or expected.
