The former site is in the Klamath National Forest and has been a part of the National Grasslands Project since 1991. The property floods in the winter and is used for grazing cattle during the rest of the year. The property is fenced and not generally used by the public. Much of the nearby area is part of a wetlands reclamation project and has been flooded. Due to the historic nature of the site, there are currently no plans to make this site a part of the wetlands area. (Source: U.S. Army Corps of Engineers) « see less

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.

Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.

Data: All data comes from the Defense Environmental Restoration Program and the U.S. Army Corps of Engineers, and will be released soon at the ProPublica Data Store. Read our methodology »
