Yesterday’s -
- Fish or ducks?- To stock? Set bag limits?
River Management Questions
- Can we fix some pieces of the system without jeopardizing others? (fishes AND ducks AND mussels?)- How much restoration is enough?
Today’s -
System level
Project level
- Build project X?- Build project X before project Y?

Problem: Navigation Pool “aging”Symptoms: Altered hydrograph, loss of depth, sediment re-suspensionOne solution: DRAWDOWNSJustification: Good for aquatic vegetation, good for waterfowl
Our multi-objective dilemma
BUT …
Mussel mortality?

Good News: Managers are embracingthe concept of ecosystem services. System Goal 5: Viable populations of native species
Limiting Factor – Loss of historical forest plant community
Example Reach Objective – Adjust dam operations to emulate water table regimes
that historically supported floodplain forest native plant communities.
Ecosystem Functions –
Soils dry & oxidize, allowing root systems to expand
Species intolerant of saturated soils survive
and expand range
Exotic grasses and forbs less
competitive with diverse native
species present
Forest plant species
complexity increases;
habitat & food resources for
wildlife enriched
ECOSYSTEM SERVICEImproved wildlife viewing,food foraging,aesthetics
Impounded water tableLowered water table

Recap
1. Upper Mississippi River System management “keeping pace” with methodology and concepts
2. Management attraction to ecosystem services
3. Potential value of tool may be greater at larger scales
