Wetlands that connect to the river (category “1”) have higher oxygen, and lower ammonia than those that don’t get flushed as often

Two major changes: Seasonal and Daily flows
Not enough water in spring & summer Too much water in winter Mostly due to Gardiner Dam Hydropeaking creates havoc for wildlife and for transportation Due to EB Campbell Dam
- Mimic the natural pattern of water flow
- Flood the delta in the spring and summer
EB Campbell can only do so much
- In spring and summer, increase
minimum flow
- In late fall and winter, decrease
maximum flow
