Many different river restoration techniques will be used in the Kootenai River Habitat Restoration Program. Examples of different techniques that could be used alone or in combination to address conditions in different project areas include:
- Excavation or dredging to create additional depth in specific areas, or to change the water velocity.
- Regrading of river banks to prevent erosion and encourage plant growth.
- Construction or enhancement of floodplain areas to store sediment and restore riparian vegetation, as well as revegetation of floodplains.
- Construction or enhancement of wetlands to help filter and store sediments, supply nutrients, and create habitat.
- Construction, enhancement or reconnection of side channels to provide habitat for fish, reduce sediment and reconnect floodplains.
- Installation of bank structures such as bioengineering, large woody debris, and sod and wood toe structures to prevent or reduce bank erosion, and to facilitate development of bank vegetation.
- Installation of instream structures such as boulders, logs or pilings to redirect flow to protect banks, create pools, and alter hydraulics. This flyer includes photos and descriptions of some of the most commonly used techniques.
