Indian-Moxlie Creek Drainage Basin Plan

Indian/Moxlie Creek Comprehensive Drainage Basin Plan, May 1993, adopted by the City of Olympia and Thurston County.

 

Note: The basin plan on this Web page has been divided into several PDFs to make it easier for viewers to find information.  Although the PDFs are generally about 25-35 pages long, they still take time to load because the PDFs were created by scanning a paper-version of the document (as opposed to simply converting a Word document to a PDF).


Instead of waiting to view the files through this web site, a better choice is to right-click the underlined hyperlink and then "save target" (ie., save the file) to your own computer and open it from there. Use the magnifying glass in Adobe to zoom in.
