We can keep Lake Vesijärvi clean by working together
Management procedures:
• Management fishing
• Artificial oxygen supply
• Mowing of water plants in summer and in winter
• Improving of water flow rates via dredging
• Improvement of the methods used in cultivation of fields
• Establishment of new buffer zones
• Creation of wetlands and sedimentation ponds
• Containment of agricultural runoff in major drains
• Improved treatment of wastewater in sparsely populated areas
• Reduction in the stormwater load
The management programme also includes studies to provide guidelines for further actions; monitoring of the lake’s condition and nutrient loads; and extensive communication efforts such as exhibitions, newsletters, and extension of education and information efforts to children and teenagers.
