Hydro and Wetlands
• Restoring wetlands can improve the flow
regime for hydro production
• There are additional and multiple benefits
• It provides a framework for dealing with
possible issues
• There may be grants available

Hydro and Wetlands
Restoration measures can modify the
hydrograph by lowering the peak flow and
prolonging the duration of an event.
They can also help maintain basal flows during
low rainfall periods.
The result is more consistent generation of
energy plus management of sediments,
grasses and other debris.
Hydro and Wetlands
Benefits to our environment can include:
• Increase in wetland plants and animals
• Recharging of groundwater sources
• Increase in amenity
• Probable increase in carbon storage
• Potential flood management contribution
• Management of erosion and sediments
Hydro and Wetlands
Examples of possible difficulties:
• Multiple landowners, may be disinterested
• Time and cost implications
• Requires excellent project management
Hydro and Wetlands
If you can show that the project will raise Water
Framework Directive status or provide
community benefit through increased amenity
or lowering of flood risk
Then grants are possibly available from local
authorities and government agencies.
Hydro and Wetlands
So, if you are wanting to develop a site for hydro
or increase the efficiency of an existing
scheme, then:
Scope out the potential for restoration of
natural features and characteristics upstream.
This can bring you and other members of society
benefits.
It can also benefit our environment.
