• CBFWA -- Research, Monitoring, and Evaluation
• Habitat-based program -- hyporheic zone is poorly
• understood component of 1) stream habitat, 2)
  connectivity,
• and 3) natural flow regime.
• Identify current condition and monitor trends in
  stream
• temperature and fine sediment in spawning
  gravels.
• Specific Needs
• Protect or restore hydrological connectivity
  between rivers and
• adjacent ecosystems
• Protect or restore functions of key alluvial
  river reaches
• Protect or restore natural seasonal
  fluctuations in discharge
• and water temperature
• Reduce accelerated rates of erosion to restore
  more natural
• stream sediment budgets.
