Drainage Basin Protection Sought Water agencies in Washington and Clackamas counties say they want more protection for their drainage basins from deforestation, especially the areas alongside rivers and close to watersheds. The Bull Run drainage basin is completely protected from deforestation, but in other areas west of the Cascade Mountains, especially around the Clackamas river and its tributaries, many areas of forest have been cleared. This has devastated the natural environment and even residents of distant urban areas further downstream are facing increased problems as a result of deforestation.
