Hola Lake is a transnational cooperation project between four research oriented organisations. Funding is from five Finnish LAGs and a Swedish LAG:

1. Project goals and beneficiaries of the cooperation

Lakes have great economical, recreational and ecological importance for the area and people therein. Several lakes suffer from eutrophication which threat the sources of livelihood as well as attractiveness of the area. This project aims at improving the ecological status of lake environment by developing lake restoration methods in a holistic way. The holistic approach takes into consideration both external and internal loading, which means actions both in the lake and in its catchment area.

The main focus of the project is on lake littoral area. Profound cooperation between organisations well-experienced in lake restoration will create a fruitful platform for sharing information and gathering best practises as well as developing new ideas for the most efficient measures for lake restoration. In successful lake restoration time scales needed are usually long and the involvement and commitment of local people in the management of their own environment is of crucial importance.

International cooperation provides unique possibilities to widen the area of project implementation and increases possibilities to find new ideas and know-how. Combining local networks of project partners will attract more people in local areas and solidify existing relationships between people who actively participate in lake management activities. This project is a fruitful example of continuation of the international cooperation, which was built between LAGs and project partners during the previous international Leader project, Hola Lake (Holistic approach in lake restoration).  

Main goals for the project are following:  

  1. Improve the knowledge and methods on the reduction of external loading
  2. Improve the efficiency of methods on the management of fish stocks
  3. Enhance the local and commercial use of fish management catch
  4. Improve the knowledge and methods of management of reed beds
  5. Enhance the use of harvested reed as raw material
  6. Increase the knowledge and involvement of local people in monitoring and control of harmful, invasive species
  7. Increase cooperation between local residents and surrounding organizations
  8. Increase international cooperation and create professional networks

2. Organisations which implement the project

Joint activities

Three joint workshops

Partners will organize workshops in turns: One workshop by Lake Vesijärvi Foundation, one workshop by LUVY, and one workshop by the Swedish partner. Detailed programme for the workshops will be planned during the project, but the workshops follow the four themes of the project:

  • Reduction of external loading, late summer 2022 (Regito AB/Osby)
    HOLA LAKE II 1st international workshop 13.-15.9.2022, Osby, Sweden. Programme and presentations
  • Fish management and commercial use of management fish catch, winter/spring 2023 (LUVY)

A manual of best practices

Common manual about Nature-based methods in water management has been made as joint output of Hola Lake II. Manual consists of good practises and experiences that project partners have met in working within lake management questions. Manual has been written in Finnish and in Swedish and published in electronic form in order to avoid any expenses and enable sharing the document with everybody having an internet connection.
