Sitkoh River Existing Conditions The following images represent the existing conditions for the upper Sitkoh River crossing and the work area along the current diverted river channel. The lower work sites are normal forest conditions and pose no unique difficulties to the job. All references to right and left banks are as water flows facing downstream.

Access Road Photos Access road photos illustrate road condition in 2010. A portion of the Sitkoh River currently runs down the access roadway. The successful Contractor will need to move an excavator up the road / channel in the wet and flowing conditions. The road / stream will improve the road surface to the minimum necessary to get a dozer and a 6 wheel drive articulated rock truck to the old channel access point. The dry aggraded channel will be used to develop gravel for further improvement of the road surface to haul / drag logs and rootwad trees into the project area. Additional stream materials will be stockpiled for channel closure along this roadway and to construct logjam with gravel backing plug the diversion inlet. All work in this section is done under Equipment Rental pay items.
