L106 SP “ Water body code according to the Lielupe river basin management plan. Located in the territory of Kemeri national park, Dunduru meadows (Dzukste parish, Tukums county).
Summary
The river flow regime was restored by re-meandering the river thus restoring also the floodplain. In total 2,1 km long river stretch was restored by digging and damming channelled lower stretch of the river Slampe, Lielupe River Basin District, Latvia. In parallel, hydrological regime was created in floodplain meadows along river in 105 ha. The project was implemented in 2005 with financial support of the EC LIFE Environment programme.
