Approach
Increase aquatic habitat resilience to low summer flows.
Tactics
- Increase off-channel habitat and protect refugia in side channels and channels fed by wetlands.
- Protect wetland-fed streams that maintain higher summer flows.
- Design channels at stream crossings to provide a deep thalweg for fish passage during low-flow periods.
- Increase deep water habitat and channel morphology.
- Reduce width to depth ratios to reduce solar radiation in stream.
- Maintain vegetation density and composition for optimal water balance and snow accumulation.
- Restore mid-and high-elevation wetlands that have been altered by land use.
