Why Dam Removal?
• Improve the ecological status of rivers
• Many dams are old and obsolete
• Renew licence or major maintenance coming up
• Hazard (loss of life and significant economic loss downstream if they fail; recent flooding)
• Create new economic opportunities
• To enjoy rivers because they are great
