Remedial Strategies in Regulated Rivers, Lycksele (Sweden), Regulated Rivers: Research & Management. This paper summarizes recent examples of measures to remediate the ecology of regulated and fragmented rivers in boreal and temperate regions. The catchment area is suggested as the most appropriate scale and framework for such measures. Suitable measures may include reinstatement of flooding and productivity levels, management of nuisance growth of aquatic macrophytes, rehabilitation of depauperate riparian zones, increased habitat diversity, stocking of fish and construction of bypass channels for fish migration. Finally, an overall approach to remedial measures is proposed in which they form part of an integrated catchment management for regulated rivers.
