Ali Long Rearing Channel Habitat Improvements-
Upper Methow River
2
Overall Goal For The Methow Subbasin
to restore and protect the abundance,
productivity, and diversity of biological
communities and habitats with the Subbasin.

3
Additional Goals To Guide Fish, Wildlife
Habitat Activities Are-

• use of strategies that rely on natural
  production and healthy habitat to achieve
  restoration and protection goals
• ...passing on to future generations a
  functioning ecosystem capable of supporting
  self-sustaining populations of anadromous and
  resident fish

4
Protect intact healthy habitat and restore
habitat connectivity and overall habitat quality
in degraded areas.
Yakama Nation Objective One

• improved instream base flows,
• restore cut off side channels...
• remove constrictions and constraints with the
  channel migration zone

Yakama Nation Strategy One

Methow Subbasin Habitat Goal
to restore and maintain normative biological
and physical processes such that healthy
indigenous populations of aquatic and terrestrial
species can sustain themselves over the
long-term.

Limiting Factors Addressed- Physical

• Increase floodplain conveyance.
• Increase channel complexity.
• Increase groundwater storage capacity.

Limiting Factors Addressed- Biological

• Increase off-channel rearing capacity for newly
  emergent fry and parr late March through August.

Project Objectives
Objective 1. Conduct a geomorphologic-hydrologica
l assessment of the side channel and adjacent
main channel.
Objective 2. Reconnect the side channel to the
main channel.
Objective 3. Increase side channel complexity .
Objective 4. Monitor and evaluate project the
project in terms of usage by fish and changes in
channel formation of the side channel.
