The Entiat Water Resource Inventory Area 46, or WRIA 46, Management Plan was completed in 2004. Over the course of eleven years numerous individuals spent countless hours working toward the watershed vision that is captured in the content of the plan. A major goal of the Entiat Watershed Planning Unit was to produce a living watershed management plan – one that will grow, be added to, and improved over time.  In keeping with that spirit, the group views this document as a “working” final version of the WRIA 46 Management Plan envisioned under the Watershed Planning Act.

The EWPU fully anticipates revisiting and updating the plan in the years to come, and hopes that the WRIA 46 Plan will contribute valuable information and local input to other ongoing local and regional processes such as salmon recovery planning.    

Both the plan and appendices are accessible for viewing and downloading via the links below.  Blue text hyperlinks to technical reports, specific sections, and additional information have been embedded in each chapter to aid in navigation. 

If you note any errors or omissions while reviewing the document, please notify us of the error, on what page it lies, and the appropriate correction.

We will use the information you provide to generate an electronic summary of errata that will be posted on this site, and used for future updates to the plan. Adobe Acrobat Reader software is required to view the files. To download a free copy visit the Adobe website.
