ANEP: Tillamook Bay Tillamook Bay is located on the north Oregon coast, about 80 miles west of Portland. The region is known for many things, including tourism, fishing, logging, its natural beauty and abundant rain. Europeans attracted to the fertile floodplain first settled the Tillamook Bay area in the 1800s. Today the area supports a significant farming population and is home to some of the nation's finest cheese and ice cream.

Facts About the Estuary

  • About 25,000 people live in the 597 square mile watershed.
  • The cooperatively owned creamery, in operation nearly 100 years, is the second largest marketer of natural cheddar cheese in the nation and a major local employer.
  • Dairy farming, logging, and sport and commercial fishing are the foundations of the local economy, although the fishing industry has declined in recent years.
  • Tillamook Bay has been rated as Oregon's premier recreational shellfishing area.
  • Up to 59 species of fish live in the bay at various times of the year, including chum salmon, listed as sensitive by the state, and federally listed threatened coho salmon.

Health of the Estuary

  • Since 1867, sedimentation has decreased Tillamook Bay water volume by 20 percent.
  • Seventy-two percent of the intertidal marsh has been lost due to dredging, diking, filling, ripraping and floodplain development.
  • Significant sections of all five major rivers in the Tillamook Bay Watershed are water quality limited.
  • Bacteria from dairy farms, failing septic systems and municipal sewage overflows during flood events play a large part in water quality problems. Commercial shellfish beds are often closed to harvest for up to 90 days per year due to excessive bacteria levels.
  • Summer stream temperatures in parts of all five major rivers exceed the maximum standard for spawning and rearing salmon.

Accomplishments of the Estuary Program

  • Planted 105,000 trees along riparian areas-a significant portion by watershed councils and school groups.
  • Installed over 54,000 feet of fencing along rivers that border dairy pasturelands, effectively keeping livestock out of waterways.
  • Improved 655 miles of forest roads to decrease sedimentation problems.
  • Secured $1.1 million in federal and state grants for wetlands restoration.
  • With several area schools, initiated development of an environmental education curriculum and outdoor learning labs.
  • Replaced outdated tidegates with "fish-friendly" ones that allow water flow in both directions.
