Instream Habitat Assessment Summary Overall, the Luther Road habitat restoration project should be deemed a success. The condition of habitat in the reach prior to the project was poor, but it is now

  • n a trajectory toward very high quality.

The abundance and distribution of pool habitat in the reach is a major asset. Three backwater pools were mapped this year. These habitats are highly valuable year-round, as they provide low energy areas for fish to feed and rest. Greater quantities of wood within the pools will provide the needed cover habitat while creating the hydraulic energy necessary to moves sediment out of the pools and maintain pool depth.

Geomorphic Monitoring

Geomorphic Monitoring

Sediment Mass Balance The mass balance analysis produced a net fill in the project area of 1,135 cubic yards of sediment. This material, which represents approximately 20% of the total volume of aggraded material in the project area, must have come from upstream reaches. Key Adaptive Management Areas

  • 1. Protection of the sewer Interceptor crossing,
  • 2. Grade control at the upstream end of Reach C to protect

against the potential for headcut migration, and

  • 3. Right bank stabilization along the avulsed channel to

protect the overlook structure.
