Spawning gravel beds and juvenile fish habitats

Spawning gravel beds and juvenile fish stone habitats have been built and/or maintained in Tuusula, Hyvinkää, Nurmijärvi, Riihimäki and Hausjärvi.

Water Pockets Project

The project included a catchment area study to identify ways to slow down runoff water from peatlands, forests and agricultural areas within the watershed. Possible measures include bottom dams, irrigation ponds, improving the functioning of existing basins.

At the same time, the project explored whether it would be possible to improve irrigation opportunities during dry periods, reduce flooding, decrease the leaching of valuable soil and nutrients from fields into water bodies.

Along tributaries, 27 potential sites were identified, and landowner consent was obtained for 19 locations.
Participating Rotary clubs included: Hyvinkää, Järvenpää, Nurmijärvi, Nurmijärvi–Klaukkala, Tikkurila, Tuusula, Vantaa–Myyrmäki, Riihimäki and Helsinki Koillinen.

Measures in the Seurasaari Water Area

Project idea: Seurasaari water body

The Seurasaari water body (Laajalahti / Broad Bay) — the entire water area north of Lauttasaari — is the most degraded water body in the Helsinki metropolitan region. Cyanobacteria blooms occur in Laajalahti almost every summer shortly after Midsummer. In 2025, the bloom appeared in shoreline waters only in August, but it was particularly severe. The key question is: What can be done to improve the situation?

Water Protection Actions by Eastern Rotary Clubs

Water Protection Work by Espoo Rotary Clubs

Gumböle Fish Ladder

The Rotary Club of Espoo participated in the Gumböle River fish ladder project between 2013 and 2020.
Cooperation with the City of Espoo and the Uusimaa Centre for Economic Development, Transport and the Environment (ELY Centre) began in 2013 when the planning phase started. The river contains a four-metre-high mill dam from the 18th century, protected by the Finnish Heritage Agency, which prevents migratory fish from reaching upstream spawning areas.

Thanks to an initiative by Rotary representatives in 2015, the fish ladder was constructed on the eastern side of the river using a solution that saved hundreds of thousands of euros. The final cost was approximately €250,000.
The project required extensive planning and multiple permits, including building permits, operational permits,  landscape work permits, water construction permits, approval from the Finnish Heritage Agency.

All permits were obtained in early 2020, and construction began in summer 2020. The fish ladder was inaugurated on 21 October 2020. The Rotary club continues to act as guardian of the fish ladder, carrying out inspection visits a few times each year to remove debris blocking water flow and eliminate invasive plant species.
