TES staff prepared an Environmental Assessment (EA) for the Bureau of Land Management and the Western Shasta Resource Conservation District in compliance with the National Environmental Policy Act (NEPA) for the Olney Creek Fish Barrier Removal Project. The project involved the modification of an obsolete diversion dam on Olney Creek, a tributary to the Sacramento River, near Redding, California. The dam was acting as a migration barrier to adult and juvenile salmon, steelhead and resident rainbow trout. Funding was provided by the Cantara Trustee Council to mitigate for resource damages caused by the 1991 chemical spill at the Cantara Loop over the upper Sacramento River. TES staff coordinated the completion of historical and engineering evaluations by other consulting firms to support the EA. Based on the EA, the Bureau of Land Management approved a Finding of No Significant Impact (FONSI) and the project was successfully implemented in the fall of 2003.
