KLAMATH RIVER DAM REMOVAL

INFORMATION CLEARINGHOUSE

This webpage is a resource where you can find and download studies relevant to dam removal on the Klamath River. Most of these studies are from outside sources and are provided here for infomational purposes.  To view a study, click on the title, you can then use "Save As.." to save the file.  Alternatively (Windows), you can right click, select "Save Target As.." and save the file directly to your own computer.   

This page is still under construction, and more studies are being added, so check back frequently. 

If you have a study that would be appropriate for this page, or if there are any broken links, etc. please contact Michael Belchik, Senior Fisheries Biologist, Yurok Tribal Fisheries Program (530)625-4130 x1617. 

The studies are organized by informational categories, and some studies may be found in more than one category: 

Sediment

Fisheries

Engineering (including cost of removal)

Economics

Water Quality (including Toxic Algae Studies)
