Efficiency and targeted measures for catchment area work in the Eurajoki river basin (TäsmäTeho)

The project implements practical measures for water management and nutrient retention in the catchment areas of the Eurajoki, Köyliönjärvi, Pyhäjärvi, Pyhäjoki, and Ylänejoki watercourses.

Project measures:

  • Implementation of practical water management and nutrient retention measures (e.g., wetland restoration, piloting of adjustable weir solutions). The project also involves planning catchment-level solutions and surveying restoration needs.
  • Monitoring the effectiveness of previously implemented stream restoration projects using electric fishing, and conducting water quality monitoring associated with the implemented measures to assess their impact.
  • Supporting biodiversity measures that are crucial for achieving good ecological status—such as strengthening local trout populations—through targeted biodiversity actions.

The project has three main objectives:

  • To reduce nutrient and suspended solid loads entering Lake Pyhäjärvi and Lake Köyliönjärvi.
  • To maintain the effectiveness of water protection measures and increase understanding of methods to improve the performance of previously implemented measures.
  • To generate local biodiversity benefits in areas dominated by agriculture and forestry through water protection measures.
