The most typical factors causing the need for lake restoration include eutrophication, aggradation and paludification. These problems usually occur due to the shallowness of lakes and nutrient and solids loads from the catchment area. The reduction of external loads is a prerequisite for lasting lake restoration. Each lake restoration project requires volunteers regardless of its size.

The restoration actions are selected on a lake-specific basis according to, for example, the water quality, loads and fish stock, since the efficiency of the actions depends on the lake’s properties.

You can ask the City of Espoo Environment Department for advice. The Environment Department has provided financial assistance for local small-scale actions. Support has been granted on the basis of clear action plans submitted early enough.


Lake restoration efforts are usually organised late in the summer. However, the time may vary depending on the lake.

Various stages of lake restoration

  1. Assessing the need for restoration, general planning
  2. Basic survey of the lake’s situation (for example, loads, vegetation, fish stock and water quality)
  3. Preparing the project plan
  4. Applying for permissions
  5. Applying for any funding
  6. Restoration work
  7. Follow-up

Permissions required for the restoration effort

The restoration of lakes is governed by the Water Act. All restoration actions require the permission of the water area owner and often also the shore owner and landowner. As a rule, the party wanting to restore the lake should obtain the consent of the water area owner and the neighbours at an early stage.

You can apply for funding for lake restoration

Getting funding requires initiative from the people involved in the project, and establishing the situation and preparing the plans take up a lot of time. The project may be eligible for public funding if it is highly significant and actively supported by the local people. When planning the project, you must maintain contact with the funding provider from the very beginning.

Small restoration projects may be carried out as a community effort or at the expense of joint owners or residents. Support for various measures may be applied for at the City of Espoo Environment Department. Major projects usually require public (state, EU or city) funding in addition to private funding.

Partners in co-operation

Lake restoration is of interest to a wide variety of people. Partners in co-operation may include water area owners, joint owners, fishing areas, landowners, property owners, fishing clubs and conservation associations.
