Title: Freshwater Ecosystems
1Freshwater 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
3Cedar 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)

7Cedar 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)
8Sacramento 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

12Lessons 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
13Lessons 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
