Good news for Nooksack salmon

Maybe this ban will help us seek ways to restore floodplains in western Washington after the massive modification of them (from the salmons’ perspective) by large woody debris removal, dredging, diking, development, etc.

State bill would ban new urban growth in floodplains

Law could affect future city planning along Nooksack River
JARED PABEN

The bill, which has passed the House and Senate and is headed for Gov. Chris Gregoire’s desk, would prohibit designating new urban growth areas in floodplains, although there are several exceptions that would still allow it.
To read EHB 1967, the bill that would ban expansions of urban growth areas into floodplains, go to apps.leg.wa.gov/billinfo, and type in 1967 into “Search by Bill Number.”

Fish Response to Shoreline Habitats

Comparing along-shore snorkel surveys between cobble beach, sand beach, rip rap, deep rip rap, and overwater structure.

We see biggest difference when you have sub-tidal modifications.

Gastric lavage of juvenile Chinook: insects dominate in shallow habitats, plankton/benthic dominate when shoreline is steep.

At Olympic sculpture park, we looked at pocket beach and subtidal bench before and after construction.

Pocket beach example:

  • 94% juvenile salmon and few predators
  • lots of post-larval fish ~3cm

Duwamish turning basin example:

  • Chinook only use deeper portions; chum use both shallow and deep

Seahurst park (invertebrate example) where they took away a sea wall:

  • higher diversity in first year, though abundance is still lower than reference site
