Cooper Creek Reservoir and
the City of Sutherlin
| 11/15/02: | Logging began last month on schedule in spite of public concerns, and Phase 1 of the project is now almost complete. |
Instead, Lone Rock Timber has erected a business sign in the public park facing the hillside that will be almost entirely clearcut over the next 40 years and maintained as an industrial tree-farm. The sign says that clearcutting and spraying the watershed will be good for Sutherlin, including a good educational experience.
Lone Rock Timber's written plan, submitted with notification to start logging on October 14, says that a portion of slopes have a "potential for shallow slope failures". Plans to prevent landslides into the reservoir include retaining all ground vegetation to within 20 feet of draws. This would be the ground vegetation left after they spray it with herbicides in preparation for the logging. Additional precautionary measures include "stringing a cable across the draw... to increase the barrier potential to any material reaching the lake in case of a slope failure."
The Lone Rock Timber clearcut is in an area mapped by DEQ as "sensitive" for "High Soil Erosion Potential". The clearcut will be just above the Dam holding back the Cooper Creek Reservoir. Below the older earthen dam is a relatively new trailer park with hundreds or thousands of people living there. Sutherlin's evacuation plan for the dam states that "should [the dam] fail without warning, extensive loss of life and property damage would likely occur." The evacuation plan also says, "any landslide that could move into the reservoir rapidly displacing large volumes of water, would be especially dangerous."
The Oregon Water Resources Department, Safety of Dams assessed the situation last spring. They concluded that "Floating materials accompanying a debris flow landslide into the reservoir" could "obstruct the entrance to the emergency spillway" and "cause complete failure of the dam". They recommended three precautionary measures: 1) install a backup system during harvesting activities capable of pumping water from the reservoir; 2) update an Emergency Action Plan referencing the timber harvesting, with instructions for evacuation of downstream residents; and 3) all slash be removed during logging.
None of these recommendations are in place.

Most of this watershed is industrial private land and scheduled to be clearcut and sprayed with herbicides and fertilizers within the next 20 years. A decision by BLM to facilitate this was recently made. Umpqua Watershedsprotests this decision. What do you think? Would you permit your water source to be degraded? Even though the official comment period is over, you can still voice your opinion by emailing BLM.

Cooper Creek Reservoir
and the City of Sutherlin
The City of Sutherlin does not own the watershed that feeds their water supply. Lone Rock Timber owns it and they intend on logging most of it in the next 20 (or so) years. Lone Rock wants to clearcut and spray herbicides on the Cooper Creek watershed on the south side of the Reservoir, 1300 acres known at the "Wahl Tract Tree Farm." In the next 10 years Lone Rock plans to clearcut and spray about 500 acres, and the rest could be clearcut and sprayed throughout the following decade.
Forest cover is critical for the watershed to supply as much clean water as possible to Sutherlin. Once the forest cover is logged, it will take at least 30 years to provide the same amount of clean water that it provides now. Unfortunately Lone Rock Timber intends to take it all within 20 years. Will the fastest growing city in Douglas County still have enough clean water in 20 years?
BLM is now accepting your comments on the question: Shall we give Lone Rock Timber our public forests to facilitate the logging of the municipal watershed? By coincidence, the few acres of public land in the area contain some of the highest peaks. Lone Rock wants to road and clearcut the BLM forests (described as "mature and old-growth) to put up their yarding towers so they can extract their trees with less expense than helicopter yarding. One parcel of public land adjoins the City of Sutherlin and one is above Cooper Creek Reservoir. The BLM has said the public forests Lone Rock wants to clearcut are "Mature and Old Growth" forests.
The two areas that involve public land are:
