Nagyszéksós Lake, Csongrád county
Summary
The Nagyszéksós-tó project aimed safeguarding natural and recreational functions of the Nagyszéksós lake protected area through the improved retention of water from excess water periods 1.2 million m3 and the provision of surplus water from the nearby village's water treatment plan giving extra treatment through a newly developed wetland area. The other goals of the project are the improved infiltration to the groundwater and restored drainage capacity of the water system to prevent long lasting water logging periods on agricultural fields.The nearby village, Mórahalom also benefited from the development through improved recreation conditions and cultural, educational possibilities in the area.

1.2 million cubic m (m3)
Constraints
The size of the area is constrained, bigger volume retention would threaten agricultural lands
Favourable preconditions
The main drainage channel of the district's drainage network passes by the lake. (The lake itself the area that reamined an drained)

Key lessons
The project required the compromise of the water directorate and the national park how they manage their disparate interests of water levels in the lake facing the unpredictability of precipitation events. The further expansion of such a scheme in the area would have public, environmental and private gains as well, but the parties at the moment see no means how to harmonize conflicting interests if not only public, but privately owned lands would be involved as well.
Success factor(s)

Barrier
Barrier type Barrier role Comments
Other
main barrier
In this case there was no real barrier because the area is state property, the funds enabled the purchase of the wetland location. But a similar measure - according to the official at the directorate - cannot be accomplished if arrangements with private owners should be included. The duration of such reconciliation has a huge uncertainty and big probability of failure that it cannot be financed on a closed time frame project bases.
Driver
Driver type Driver role Comments
Balancing different objectives
main driver
The obligation of the water authority (to provide safety against flood or water logging threats are in contradiction with the environmental management objectives of the national park. Because the lake serve as a buffer for storage of the surplus water. The applied solution is a way forward from this situation, but without the financial sources of the operative program no sources would be attained.
Availability of subsidies

Direct benefits
1666,66662597656
Direct benefits information
There are avoided costs. According to the predictions the upgraded situation will decrease the total maintenace costs that emerged previously at the two organisations (water directorate, national park)
Ancillary benefits information
There is no economic assessment of the miscallenous benefits. These could come from recreational activities, nutrient load mitigation and habitat services.
Costs investment
747095,25
Costs investment information
New water supply chanel, creation of wetland, reconstruction work inside the lake, reconstruction of drainage channels.

Costs operation maintenance
1666,66662597656
Costs operation maintenance
This is the maintenance cost of the channels. Additonal cost will emerge in case of severe water shortage (reference to the water depth), the pumping of treated water to the constructed wetland to start supply the lake will start. It will have a cc 15€/day cost.

Information on Ecosystem improved biodiversity
The eutrophication process that threatened the lake was changed, the water lily (Nympheaetum albae) appeared again in the lake.

Information on Ecosystem provisioning services
The biomass of the lake now serves as feedstock for the buffalos. A recently finished, paralel ecology pilot-project applied water buffalos (Bubalus bubalus) to repel invasive species from the area. The first results of the program are positive.
