Learn about salmon 

What makes a healthy salmon?

Salmon are sensitive to water conditions, which makes them good indicators of water pollution. Salmon need certain conditions to be healthy:

  • Streamside vegetation and stable steam flows
  • Cool, clean water with enough oxygen
  • Clean, loose gravel to protect salmon eggs from predators and allow water to flow through the eggs for oxygen
