    Governor John Kitzhaber's Willamette River Basin Task Force reported in that non-point-source pollution entering the Willamette system during periods of high precipitation far exceeded point-source contamination in the waterway. They are used to regulate river flows so as to cut peaks off floods and increase low flows in late summer and autumn, and to divert water into deeper, narrower channels to prevent flooding. The natural resource inventory was supplemented by a detailed reconnaissance soil survey covering the subbasin. Cathedral Park and St.

    A boat of her size could load 1, to 1, bushels a trip. Ground-water in the permeable units in the lowland discharges to the major streams where there is a good hydraulic connection between aquifers and streams. Upper-river tribes caught steelhead and salmon, often by building weirs across tributary streams. Restoration on a landscape level has shown promising results Holling and many riparian and wetland restoration projects throughout the northwest have inadvertently improved habitats for non-targeted species.

    Willamette Falls was impassable. Long-term water-level declines are observed in wells open to the Columbia River basalt unit in areas with concentrated pumping. The report pointed out that urban areas contributed a higher pollutant load per acre than rural land, although the latter produced a larger overall quantity because of the infinitely greater area involved.
