Kis-Balaton Water Protection System

Phase I: 1981-1985, 1800 hectares, 21 million m3, average depth – 1,16 m

Phase II: 1984-1993-

2014,

5100 hectares, 64 million m3, average depth – 1,25 m

Embankment: 124 km,

Water retention time: 60 days

Water quality:Phase I. = algic lakeRhapsodic nutrient circulation

Vegetation changing, lack of macrophytes.Lack of water facilities (for example fish ladders)

Decay of the reedbed in the Ingó-grave:- Too high water-level- Flow conditions- Lack of opportunities for flexible operation

- Lack of the spawning areas- Lack of natural zonation

What can we do…?

Possible sources of conflict: contradiction betweenperceived and real professional interests

for example. inland water, vegetation in the creek bed, hunting activity.

Habitat – restorationrehabilitation

modification…

Conservation requirements for utilization of wetlands

Ensure the survival of the species to be protected

Do not hauled into alien species

Do not be harmful to the environment

Adhere to the ethical standards

Interventions aimed at protecting native fish species in protected areas

Water movement for the vegetation growthFish laddersestablish temporary water covered areasinvasive, non-native species displacement

Creating opportunities for flexible operation

Realized version of Lake Kis-Balaton Water Management system

Continuous control during implementation

and after…

Target or source of danger? Circular dam ripping

New wetlands

Temporary water covered areas.

Same aims?

Creation of temporal water body

Complex wetland

Ingó water level decreasing.

Unexpected situations, operational solutions.
