Freshwater Ecosystems
Two Case Studies
1) Cedar River Basin Management Priority 1
Protect, restore, and reconnect stream, riparian,
and floodplain ecosystems, and include buffers 2)
Sacramento RiverManagement Priority 2 Restore
longitudinal connectivity. 3) Connecticut River

Cedar River Basin Assumptions
  • More frequent and intense floods
  • 10 year planning horizon
  • Assume collaboration between feds, state, and
    local agencies
  • Land use remains constant (90 row crop
    agriculture worst-case scenario)
  • Will mitigate risk through natural infrastructure
  • Farmers, wildlife and communities will be
    impacted by floods. Policies must benefit all
    three groups.
  • (cost of doing nothing 5-7 Billion)

Cedar River Basin Actions and Costs
  • Other considerations
  • Regulation
  • Outreach and communication
  • Incentives
  • Compliance
  • New PolicyFor example 10M Require mandatory
    conservation practices for ALL Farm Bill
    participation (payments and subsidies)

Sacramento River Basin Assumptions
  • 50 year planning horizon
  • Snowpack down 60-80
  • Human population increase
  • Earlier snowmelt/drier summer
  • Growing conflict of less water from
    ag./cities/wildlife
  • Some fisheries restoration incompatible with
    water availability
  • Massive dams/levees
  • Subsidence

Lessons Learned
  • Cedar Rapids
  • Problem is too much water
  • Only 300,000 people
  • Cost of inaction major impacts on people
  • Sacramento much harder to assess
  • Problem is too little water
  • Millions of people
  • Cost of inaction loss of fish and wildlife

13
Lessons Learned
  • This is HARD!
  • Keeping in mind that were talking about climate
    change adaptation, not all the great conservation
    things we want to do already
  • Lots of examples of past studies that we could
    draw upon
  • Basins with water shortages are even harder
