| Notes | "This report describes a pilot effort at classifying PNW estuaries with regards to landscape attributes and their susceptibility to nutrient enrichment." Much data is presented. Although the report focuses on seven estuaries (Alsea, Coos Bay, Nestucca, Salmon River, Tillamook Bay, Umpqua and Yaquina), many other estuaries are mentioned, and basic statistical data is given for all PNW estuaries. The Yachats River is classified as a "tidal creek.""...an ongoing study of the Yachats River indicates that the formation of a sill near the mouth restricts exchange with the ocean to the spring high tides, essentially acting as a micro-fjord (C. Brown, unpublished data). This oceanic water advected during spring tides can form localized pockets of deeper, saline waters below a freshwater surface layer. With no or minimal exchange or turnover, the dissolved oxygen in these saline pockets declines until the next spring tide or storm." (p.44) |
