  3. What Threatens These River Environments? • Agricultural & Residential Runoff • Industrial & Urban Centers • Multipurpose Dams: • Hydropower • Flood protection • Navigation • Reservoirs/Impoundment

  4. Case Study:The Kennebec Watershed

  5. The Edwards Dam Removal: • Why it was removed? • Cost • Benefits • (e.g. Anadromous fish) • Why is this event important?

  6. Case Study:The Connecticut River Watershed

  7. A Tradition of Abuse • Discovery & Settlement • Development & Industrialization • Emerging Problems • Industry and Power Facilities • Agricultural and Residential Runoff • Decaying Structures (e.g. mines) • Recreational Boating • (Marinas & Yacht Basins) • Dams & Canals • Disappearing Fish & Wildlife • (e.g. Atlantic Salmon, Osprey)

  8. Dams • 1000+ Dams (High Head and Run of River) • Construction: 1850s-Today Source: U.S. Fish and Wildlife Service
